1 Introduction
1.1 About this Report Cassowary Coast Regional Council is a registered Water Service Provider (WSP) under the Water
Supply (Safety and Reliability) Act 2008 (the Act) and one of its legislative obligations is to provide an
annual performance report on prescribed indicators nominated by the Department of Regional
Development, Manufacturing and Water (DRDMW). The data required by the Regulator covers details
such as connected populations, asset information, water treatment and sewerage treatment volumes,
staff information, system performance, customer service and financials. The water and sewerage data
required by the Regulator was loaded into the Statewide Water Information Management (SWIM)
portal to meet the lodgement date.
In addition to the lodgement of data into the SWIM system, Council also is required to publicly publish
its performance with commentary on key indicators.
This report satisfies Council's requirements under Section 142A of the Water Supply (Safety and
Reliability) Act 2008 ("the act"), to prepare a performance report on water and sewerage services for
the 2020/21 financial year.
The report provides an overview of regions water and sewerage schemes followed by discussion on
results of some of the key performance indicators (KPI's) for water services and sewerage services
lodged in the SWIM system. The data lodged in the SWIM system is included in Appendix A.
This report also includes an overview of the Cassowary Coast Regional Council's adopted Customer
Service Standards and the performance against these standards. This year the Customer Charter was
reviewed and updated by Council. A discussion on these amendments is included.
A major component of this report documents the performance of Council's drinking water service with
respect to water quality and performance in implementing the actions detailed in the drinking water
quality management plan (DWQMP) as required under the Water Supply (Safety and Reliability) Act
2008.
The report assists the Regulator to determine whether the approved DWQMP and any approval
conditions have been complied with and provides a mechanism for providers to report publicly on
their performance in managing drinking water quality.

2 Background of Cassowary Coast Regional Council's Water and Sewerage Operations
2.1 What we do Cassowary Coast Regional Council is the water service provider responsible for delivering drinking
water to a connected population of over 25,231 water customers in a region between Cardwell and
Innisfail and sewerage services to a connected population of 14,974 in the towns of Tully, Mission
Beach and Innisfail.
Since August 2018 Cassowary Coast Regional Council has been responsible for the operation and
maintenance of the Port Hinchinbrook sewerage system, located south of Cardwell on behalf of the
Queensland Government. In August 2020 funding for this service ceased, however Council continued
to operate the facility in order to protect human health and the natural environment. On 13 May
2021 a resolution from Council was passed to cease maintenance. No maintenance has been
undertaken by Council staff, unless by the express direction of the CEO, since 30 June 2021.
To support these services Council undertakes the following functions:
2.1.1 Provision of water distribution, sewage transportation and treatment including:
Demand forecasting and management
Asset maintenance and renewal
Operational and maintenance activities associated with the running of 6 water supply intakes,
1 water treatment plant, 9 water supply chlorination stations, 31 water reservoirs, 14 water
pump stations, 814 km of water mains, 2 sewage treatment plants, 58 sewerage pumping
stations, 231km of gravity sewerage and 64 km of sewer rising mains (excludes Port
Hinchinbrook assets).
Capital works to replace aging assets or upgrades to suit system growth
Trade waste management
2.1.2 Customer interface and service provision relating to:
Water meter management and data
Leak notifications from smart meter data
Residential billing and customer management
Infrastructure search requests
Development assessment
Trade waste oversight
Development and maintenance of Backflow Prevention Device register
2.1.3 Enabling functions for business sustainability including:
Strategy development
Asset management
7
Financial and people management
Community and stakeholder engagement
Regulatory and legislative compliance
Information, communication and technology
Procurement and contract management
2.2 Our Operating Environment - Water Supply Cassowary Coast Regional Council is regulated to ensure that safe drinking water is provided to the
community through a number of Acts of legislation including:
Water Supply (Safety and Reliability) Act 2008
Water Act 2000
Public Health Act 2005
Local Government Act 2009
Environmental Protection Act 1994
The Department of Regional Development, Manufacturing and Water (DRDMW) is responsible for
managing water supply allocations that are available from the creek and river systems that Council
uses as source water for its water supply system.
DRDMW (through the Regulator) is responsible for managing compliance with the Water Supply
(Safety and Reliability) Act to ensure water service providers such as CCRC provide a water supply to
consumers that meets Australian Drinking Water Guidelines (ADWG) and is safe for consumers to
drink.
Queensland Health also have responsibilities under the Public Health Act to ensure water supplies are
safe for the community. The regulatory authority between DRDMW and Queensland Health is
particularly evident for CCRC when boil water events are declared as the notifications of water quality
incidents is provided to DRDMW but approval to lift a boil water alert is issued by Queensland Health.
CCRC water supply services are managed in accordance with the CCRC Drinking Water Quality
Management Plan (DWQMP) May 2021, to ensure water supply to customers meets Australian
Drinking Water Guidelines.
Key features of the DWQMP include descriptions of each treatment and distribution scheme; raw
water quality parameters, water testing history, risk assessments, improvement plans, sampling
procedural manuals and critical control procedures. The DWQMP must be able to satisfy the
requirements of section 95 of the Water Supply (Safety and Reliability) Act 2008. The objective of the
DWQMP is to establish a risk-based management system that the Service Provider follows to ensure
the provision of drinking water to a high quality that protects public health.
The current version of CCRC’s Drinking Water Quality Management Plan is May 2021, this version can
be found on Councils Web Page. Council's DWQMP was initially approved by DEWS in October 2013.
In May 2017, Council received DRDMW formal approval of a revised DWQMP. During 2020, Council
8
completed a review of its DWQMP to reflect changes to significant infrastructure completed since
2017. This update is the approved version (May 2021) as assessed by the Regulator.
2.3 Our Operating Environment - Sewerage Services The key regulatory framework for Council's sewerage services is provided by:
Water Supply (Safety and Reliability) Act 2008
Public Health Act 2005
Local Government Act 2009
Environmental Protection Act 1994
Council's sewage treatment facilities (Innisfail and Tully) are licenced under the Environmental
Protection Act (EPA). The regulatory authority for activities licenced under the EPA is the Department
of Environment and Science (DES). Key conditions of Council's licences relate to discharge limits,
testing requirements to ensure process control, receiving waters monitoring, reporting requirements
and approved discharge and overflow locations.
Pollution events such as exceedances of discharge limits or dry weather spills must be reported to DES
within prescribed time frames. Noncompliance with licence conditions can result in infringement
notices with fines or more serious legal action.
2.4 Key Achievements in 2020/21 Our key achievements for 2020/21 included the following:
2.4.1 Water
Supplied 5,437 million litres of drinking water to an estimated connected population of 25,231
In both Innisfail and Tully, Council continued with the water main asset renewal program. The
renewal program has been focusing on the replacement of the 1930’s and 1940’s unlined cast iron
water mains which suffer from extensive internal ferric corrosion and the replacement of aging
asbestos cement mains with a history of failures.
Approximately 5 km of aging cast iron (CI) water mains and asbestos cement (AC) mains were
replaced across the region.
Resource shortage and Covid 19 restrictions did limit Council’s work program. Due to these
restrictions some water main renewals programmed for 2020/21 have been carried over to
2021/22.
Completed the deployment of smart metering to Wangan (281), Mundoo (108) and Innisfail Estate
(535).
Completed the construction of the 4.5 ML Bulgun Creek intake reservoir and associated
infrastructure.
Commenced the repair of the concrete joints at the Stoters Hill Reservoir.
Adopted the competed revaluation of all water assets.
Backflow policy adopted November 2020.

2.5 Water Supply and Sewerage Services - Background Cassowary Coast Regional Council operates and maintains four water supply schemes and three
sewerage schemes, providing safe drinking water and sanitation services to the majority of the region.
2.5.1 Water Supply Scheme Overview
The four (4) water supply schemes include:
Innisfail
Nyleta
Tully
Cardwell
Innisfail scheme is supplied from the Johnston River and is the only tertiary water treatment plant
operated by CCRC.
The Nyleta, Tully and Cardwell schemes are supplied by run of creek offtakes. These offtakes gravity
feed into the reticulation network. The Nyleta Scheme is supplemented by a bore located at Jurs
Creek. The Cardwell Scheme is supplemented by a bore located at Kennedy.
Innisfail
The Innisfail Scheme is the largest water supply scheme and is the only scheme with a designated
tertiary water treatment plant. Water is extracted from the Johnstone River and is treated at the
Innisfail Water Treatment Plant before being distributed through a water reticulation network. The
water treatment plant (WTP) has a maximum capacity of 18.2 ML/day. Treated water is pumped from
the WTP to the Stoters Hill reservoir before gravity feeding to the customers via a series of reservoirs
and pump stations. The Innisfail reticulation network includes Innisfail, Daradgee, Wangan, Flying Fish
Point, Mourilyan, Mourilyan Harbour, South Johnstone, and Mena Creek. The Innisfail Scheme has a
water storage capacity of 27.1 ML spread across ten (10) reservoirs.
Nyleta
The Nyleta intake is located on Nyleta Creek (a tributary of Liverpool Creek). Water is screened,
disinfected and then distributed through the water reticulation network. The Nyleta Scheme supplies
the communities of Silkwood, El Arish, Kurrimine Beach, Bingil Bay, and Mission Beach. Reservoirs are
located near key communities and provide both daily but also emergency storage in the advent of a
pipeline failure or boil water event. There are seven storages throughout this network, with a total
storage capacity of 9.5 ML.
The Jurs Ck bore is the other existing water source for the Nyleta Scheme. Jur’s Creek bore has been
non-functional for the majority of this period. The bore used to supply approximately 0.7 ML/day to
the Fenby's Gap reservoirs, which supplied part of Mission Beach. Clump Mt pump station was
upgraded and can now supplement Fenby’s Gap reservoir by utilizing off peak pumping (night time)
from Nyleta intake via Bingil Bay reservoir.
11
The South Liverpool intake and adjoining 3.3 ML Nyleta Hill reservoir are key initiatives to improve
water quality in the Nyleta scheme area. Automation and SCADA of turbidity sensing control valves
and pumps allow the intake on Nyleta Ck to be closed during periods of high turbidity within the creek
following heavy rainfall events. During extended periods of turbidity in Nyleta Ck, the pumps
connected to the new sub-bed filtered intake on South Liverpool Ck can be started and used to
recharge the reservoir. Typically for smaller periods of turbidity spikes in Nyleta Ck, the clear water
storage in the reservoir is ample but, during sustained periods of elevated turbidity it is also necessary
to utilise the new sub-bed intake to top up the reservoir. CCRC has observed that the new sub-bed
intake can draw water from the filters in South Liverpool Ck at below 5NTU (turbidity units) even
though South Liverpool Ck is flowing with very high turbidity (levels of 40NTU).
One of the other functions of the sub-bed intake is that it can draw sub-bed creek flows in periods of
dry weather when Nyleta Ck flows cannot meet demand. As the South Liverpool Ck intake system is
pumped, Council utilises the gravity Nyleta Ck intake as much as possible and currently runs the South
Liverpool system only when Nyleta Ck is very low, or impacted by turbidity.
Fifty micron in-line filters at Nyleta reservoir remove any of the material that passes the 200 micron
inlet screens before the water discharges into the reservoir.
Tully
The Tully Scheme is supplied by separate intakes at Boulder Creek and Bulgun Creek. These intakes
service the Tully, Mission Beach, Tully Heads, Hull Heads and rural areas surrounding Tully and Mission
Beach.
Major increases in available water storage have been completed for the Tully scheme to better
manage long term demand and to assist with clean water supply during periods of turbidity in either
Bulgun Creek or Boulder Ck. Construction was completed in December 2019 of a 4.6 ML reservoir at
Wheatleys Hill to supplement the existing 0.7ML storage. This new reservoir will supply the
communities of Wongaling, South Mission Beach, East Feluga and Carmoo. In November 2020, Council
completed the construction of a new 4.5ML reservoir near the Bulgun Creek intake and associated
control systems to address turbidity in the source water.
12
Figure 2. Bulgun Intake Turbidity Probe
Control of the Bulgun Intake reservoir will be via a system of turbidity analysers installed at both the
Boulder Creek and Bulgun Creek intakes. When the source water at either or both sources becomes
turbid and above 5NTU, a system of valves at the intakes will automatically close and water will be
supplied from the clean water stored within the reservoirs. The inlet valving will reopen automatically
when the turbidity drops below 5NTU. This system of controlling, has now been well proven at both
Nyleta intakes and at Cardwell.
Since the commissioning of the Bulgun Intake Reservoir in November 2020, along with the automated
turbidity analysis, no boil water notices have been issued to the community.
Planning is continuing for another reservoir off Hyatt St Tully that will be used to supply the Tully
township. Currently the existing Hyatt St reservoir is located at an elevation that is too low and cannot
maintain pressure to some of the higher parts of the town. The existing common main that feeds the
existing reservoir will be converted to a supply only main and a new trunk delivery main will be
constructed back into town. The first phase of funding for the new delivery main is in the 2020/21
year.
Cardwell
The Cardwell Scheme is supplied from an intake located on Meunga Creek. Water is gravity fed to the
Cardwell reservoirs for storage and distribution. A pump station and reservoir at Stony Creek supplies
the southern part of Cardwell. Total storage capacity in the Cardwell network is 2.8 ML. A bore on
13
Ellerbeck Rd near the Kennedy School also supplies water to the Cardwell Scheme. During periods of
high turbidity in Meunga Creek, the intake can be isolated and the Cardwell community can be
supplied by clear water stored within the reservoirs, supplemented by the bore. The closure of intake
valves and the start-up of the bore is a fully automated system. Major rainfall events that trigger high
turbidity in Meunga Creek are mitigated, by switching supply to the bore. Using the bore, Council has
avoided a number of potential boil water alerts. In 2019, this project was selected by the Institute of
Public Works Engineering Queensland as the best public works project under $1 million in Queensland.

2.5.2 Sewerage Schemes Overview
The three (3) sewerage schemes include:
Innisfail
Mission Beach
Tully
Sewage treatment plants (STP) are located at Innisfail and Tully. The Innisfail Sewage Treatment Plant
has capacity of 40 ML/day (Peak Wet Weather Flow). The Tully Sewage Treatment Plant has a capacity
of 12.5 ML/day (Peak Wet Weather Flow).
The Innisfail sewerage network is restricted to the Innisfail residential footprint and the Belvedere
subdivision. Thirty-one (31) pump stations collect and transfer sewage to the Innisfail STP. Treated
effluent from the Innisfail STP is discharged to Ninds Creek.
The sewerage network in Mission Beach collects sewerage from Mission Beach, Wongaling Beach and
South Mission Beach and pumps it to the Tully STP via the Mission Beach Main Transfer Station and
22 km of 300mm diameter sewer rising main. Replacement of the Mission Beach Main Transfer
Station was commenced in 2020/21 with the pumps due for installation in early 2022 as a result of
considerable long lead times and global restrictions due to the Covid 19 pandemic.
The Tully sewerage network collects sewage from the residential and industrial areas surrounding
Tully prior to pumping to the Tully STP. Treated effluent from the Tully STP is discharged to Banyan
Creek.

CCRC also operated and maintained the Port Hinchinbrook sewerage scheme on behalf of the
Queensland Government State Development Agency. This is being operated by staff from the Tully
treatment team. The Port Hinchinbrook system consists of 10 sewage pump stations and a treatment
plant. The pumping and treatment infrastructure at Port Hinchinbrook was in a poor condition when
Council commenced the operation of this facility.
In August 2020 funding for this service ceased, however Council continued to operate the facility in
order to protect human health and the natural environment. On 13 May 2021 a resolution from
Council was passed to cease maintenance. No maintenance has been undertaken by Council staff,
unless by the express direction of the CEO, since 30 June 2021.
Council has been assisting the State with design work on a replacement treatment facility for Port
Hinchinbrook but funding for this project is still to be finalised.

2.6 Our People Cassowary Coast Regional Council Water total workforce is 67 FTE (full time employees) not including
6 vacancies. The workforce is spread over a range of disciplines including treatment, reticulation, trade
waste, maintenance, supervision and management. Water also utilises up to 4 contract labourers and
up to 4 contract plumbers from time to time to assist with the roll-out of the smart metering program
and the valve and hydrant maintenance program. Discussions at the FNQROC water group have
identified that valve and hydrant maintenance is a problem throughout the region. A regional
program is being developed to assist all members with this issue.
Figure 7. Staff Composition by Gender.
The Council operates three (3) water depots, with the majority of the workforce based in Innisfail. The
gender profile of our workforce is majority male. A significant portion of the workforce is 50 years or
older. Council recognises this is an issue and is actively engaging in an apprentice employment and
skills training program. Council currently employs 8 apprentices spread across two disciplines;
plumbing and mechanical trades (fitters).

Council staff from the Innisfail, Tully and Cardwell areas have been utilised to maintain and operate
the Port Hinchinbrook sewer network and treatment facility. This puts an additional demand on staff
and resources as there has been no increase in staffing to maintain and operate this deteriorated
asset.
2.7 Our Catchments Rainfall across the Cassowary Coast catchments for 2020/21 was above the long-term averages across
the region. Significant rainfall events occurred in January 2021 for all schemes. These schemes
received twice the average monthly rainfall. April 2021 also saw higher than average rainfall across
the region. Tully received the most rainfall with 4,939 mm. Cardwell was again the driest area with
2,419 mm of rain for 2020/21.

Total stream flows of 1,954,217 ML were recorded in the North Johnstone River during 2020/21, with
342,774 ML recorded in January 2020. All other intakes are upstream of the gauging stations,
therefore it is difficult to get an accurate representation of the streamflow past the intake.
Figure 9. North Johnston River Flows
The dry conditions in the latter part of 2020 did not result in water restrictions. The decline of flows
in the creek systems in later part year associated with the dry season can rapidly change the flows and
emphasises the fragile nature of our supply sources.
The development of water security strategies to ensure options for continued water supply in
extended dry periods is still a key initiative in Council’s Drinking Water Quality Management Plan –
Improvement Plan. A consultancy brief for the investigation of options to improve water security was
developed in 2019 but was not funded in the 2020/21 budget process.

2.8 Our Emissions In 2020/21Council produced 4,236 tonnes of CO2 (up from 3,826 t recorded in 19/20) in the provision
of water and sewage services to the community. This is equivalent to 924 passenger vehicles driven
for one year1.
Of the 4,236 tonnes produced, over 2,878 tonnes were produced through the consumption of
electricity for the collection and treatment of sewage. The reasons for the increase in power usage
largely relate to the increased volumes of sewage pumped and treated in 2020/21. Sewage volumes
in 2020/21 were 30% higher than in 2019/20.
Solar systems were installed at the Innisfail WTP (100KW), Innisfail STP (100kW) in September 2020
and a smaller system at the Tully STP (27kW) in 2019.

3.3 Capital Works Projects 2020/21
3.3.1 Water Pipeline Upgrades
During 2020/21 Council continued with its renewal programme of water mains. The value of water
main renewal works undertaken was approximately $1.9M down from $2.1M in 2019/20. Output
from the construction crews was impacted significantly for the year as two plumber positions
remained unfilled reducing the capital crews from four to two.
The listing of projects below includes some projects that were commenced in 2019/20 but completed
and capitalised in 2020/21.
Typically, the major focus of the renewal programs in Innisfail and Tully has been the replacement of
unlined cast iron mains with severe internal ferric corrosion. In the CBD areas of Tully and Innisfail
existing 100mm are being upgraded with 150mm diameter to allow for long term growth and to
improve fire-fighting provision.
The replacement of asbestos cement mains in all regions is based on age, service priority and
particularly failure history. In rural areas, small scale renewals are also being undertaken of AC mains
with failure history by inserting a smaller polyethylene main inside the original 100m host pipe.
Typically the polyethylene insertion main is either a 63mm or 80mm outside diameter. This is
significantly less expensive than new construction. Fire hydrants cannot be provided on these mains
so there is some reduction in fire-fighting standard of service where Council is undertaking this form
of renewal.

3.3.2 Bulgun Intake Reservoir
During the 2020/21 financial year, Council completed the construction of the Bulgun Intake Reservoir.
This new 4.5ML reservoir was brought into service in November 2020.
The project was a key initiative in Council’s ongoing program to eliminate boil water alerts across the
region. During periods of turbidity in either the Boulder or Bulgun Creek, the intakes can be isolated
automatically and clear water will be supplied to the greater Tully community from the storage in this
reservoir. Once the creek flows are clear, flow is automatically restored back into the Bulgun Intake
Reservoir.
Figure 10. Bulgun Intake Reservoir
3.3.3 Smart Metering
During 2020/21 Council continued the replacement of water meters and the deployment of meter
transmitters (smart metering) in Innisfail and the surrounding areas of Wangan and South Johnston.
The consumption data from the smart metering is nearly real time and is now being used by Council
to identify and notify residents of water leaks. Council also uses the data for billing purposes.
As 30 June 2021, Council had approximately 5,873 smart metering devices deployed. Council has
committed to continue the installation of smart metering across all parts of the region. Approximately
1200 smart meters have been installed in the 12 month period.
26
Council’s IT Section completed work with Water and Rates Sections to fully deploy Aqualus as the
software tool which will be used for meter reads, smart meter data analysis and meter installs. The
roll-out of this software is only partially successful due to compatibility issues with Council’s Tech 1
software. The manual entry of data from Aqualus to TechOne is still required.
Figure 11. V200HT smart meter typical installation
3.3.4 Pressure Control Valve-Pingin Hill (Innisfail)
The reduction of pressure in the reticulation network has a direct effect on the amount of leakage that
occurs, in particular at night time and in periods of low demand. As part of the leakage management
strategy the pressure control valve at Spannagle Road Pin Gin Hill was upgraded with a new 100mm
above ground assembly. The project included the installation of a 180 HDPE water main under the
Palmerston Highway, replacing the existing AC and reducing the possibility of a water main break
under the highway.
3.3.5 DMA Flow Meter Mundoo (Innisfail)
A District Metered Area (DMA) flow meter was installed at the Mundoo Water Pump Station. This
flow meter is part of the leak management strategy to identify high flows as low demand periods. The
flow meter meters all water south of the Mundoo airport to Wangan and South Johnston.
3.3.6 Clump Mountain Booster Pumps (Nyleta)
The Clump Mt booster pump station was re-established to provide an additional source of water to
Mission Beach. Traditionally Mission Beach is supplied from Jurs Creek Bore and Fenbys reservoir on
the El-Arish Mission Beach Road. This pump station will now supplement the reservoirs at Fenbys Gap
by supplying water from Nyleta Reservoir via Bingil Bay. Water will be pump up to the reservoir during
the night and released from the reservoir during the day.
3.3.7 Bulgun Chlorinator Activate Pressure Control (Tully)
Active pressure control was implemented at Bulgun Chlorinator as part of the Leak Management
Strategy. The existing pressure reducing valve on Old Tully Road, Bulgun was fitting with an actuated
pilot valve to allow the SCADA system to vary the pressure in the network. The pressure reducing
27
valve is now operating at a reduced pressure during the night at low demand periods. This will help
reduce minimum nigh time flow and the volume of leakage in the Tully Water Supply Scheme.
3.3.8 Replace roof on clear water tank (Innisfail)
Security of water storages from rainwater ingress, foreign substances and vermin is an important
element in the supply of potable water. The roof of the 24 metre diameter reservoir was replaced
with new sheeting as the sheets were showing deterioration due to corrosion.
3.3.9 Innisfail Water Treatment Plant - Backwash No2 Drive
A replacement was required for a failed variable frequency drive for the WTP Backwash Pump No2
3.3.10 Innisfail River Pump and Drive Overhaul
The Johnstone River intake pumps were installed in 2000. One of the Variable frequency drive
controllers failed requiring replacement with a new drive. While shut down the pump was also
reconditioned.
3.3.11 Planning and Design Activities
During 2020/21 forward survey and design activities was undertaken to ensure that capital renewals
of water mains can be continuously implemented.
The following forward survey and design project was undertaken in 2020/21:
Water FS&D - Margaret-Victoria St Silkwood
Water FS&D - Blackman-Cook-Henry-Bryant
Water FS&D - Fitzgerald/Bunda St Innisfail
Water FS&D - Martin/Ryan St Innisfail
Water FS&D - Royston St El Arish

Water FS&D - Mars St Tully
Water FS&D - Mcquillen St (Mars-Watkins)
Water FS&D - Cook St Tully
Water FS&D - Webb St Tully
Water FS&D - Jubliee Bridge mains relocation
3.3.12 Asset Management Plan
The Water Asset Management Plan is planned for review in 2021/22. The current asset management
plan has identified a shortfall of renewals expenditure of $53.3M over 10 years (based on current
renewals budgets). Future renewal budgets will need to increase to better balance this shortfall but
planning work also needs to be done to optimise the renewals program.
Water mains failure are becoming more frequent in AC mains in the Innisfail Estate and Pigin Hill areas.
These assets are seeing a reduction in useful life of 10 years or greater. Consideration should be given
to prioritising a renewal program in these areas.
28
It is recognised that much of the rural network is not economically viable in that the income stream
from water charges does not offset depreciation and operational costs for the asset. Further work
needs to be undertaken to rationalise these uneconomical assets. This may include options to
downsize mains or to decommission mains. It will take considerably more investigation to develop
policy documents to support the decommissioning of mains. Where mains are requiring urgent
renewal and downsizing is practical, Water Section is using polyethylene pipe pulled through the
existing host pipe to achieve a more economical renewal. This methodology was adopted in the 2020
revaluation of water reticulation mains in rural areas. A significant number of 100mm pipes in rural
areas with minimal connections have been identified as being suitable to be downsized and the
replacement cost in the revaluation process of these assets reflects a 63mm polyethylene pipe pulled
through the original host pipe rather than a 100mm conventionally constructed water main.
3.4 Our Customers There has been a slight increase in the population receiving water supply services since 2019/20. It is
estimated that Cassowary Coast Regional Council supplies 25,231 people with safe drinking water
distributed as shown below. The prediction of population figures contains a number of assumptions
which can impact the accuracy. For example, the numbers of people in each household (connected
residential properties) are based on Bureau of Statistics Information. Vacant residential connections
are excluded from the results in Table 2. The methodology adopted by Council in these predictions
has been fixed for some years now.

3.5 Our Supplies Of the 5,434 ML of potable water supplied during 2020/21, 40% was used for residential purposes,
20% was used by commercial purposes (including businesses such as backpacker accommodation,
sugar mills, hotels/motels, laundries and cafes), 40% was unbilled (non-revenue).
Water referred as “other” includes non-revenue water such as losses from leaks/mains bursts and
metered water used for mains flushing and auto-scours, and water from overflowing reservoirs.
Figure 12. Break down of drinking water supplied to customers
The breakdown of non-revenue water for each scheme is shown in the Table below. The largest
component of non-revenue water is “unaccounted for”, being losses from a combination of leaks,
faulty meters, illegal connections, illegal standpipe use, or overflowing reservoirs.

The implementation of these strategies has been slow during to insufficient resources and the
constant pressures to deliver services. Strategies that have been implemented to date include the
replacement of the aging meter fleet, smart metering, and bulk flow metering to the reticulation
network. These works will continue over the next few years plus other strategies including increased
levels of pressure zone management additional and leak detection surveys will be employed.
An internal audit report into Water Loss management and Water Revenue Assurance in June 2021
highlighted the need to maintain the rollout of the smart meter program to reduce the amount of
non-revenue water attributed to faulty meters.
In addition to the smart meter program Council continues to invest in network reticulation metering
and pressure reduction zones. By the end of 21/22, it is expected that Council should be starting to
see greater evidence of the value of its investment in these water loss strategies.
Realistically the identification and rectification of leaks in the reticulation network will continue to be
an ongoing challenge. Council has a vast network of aging water mains and physically locating minor
leaks that do not exhibit surface water flow is difficult, time consuming and problematic.
The volume of water supplied per residential connection utilises metered consumption data and
highlights the residential consumption trends in each of the supply areas. Tully Scheme residents
consume the most water with an average of 289 kL per connection, an increase of approximately 20%
from 2018/19. Innisfail Scheme residents consume the least at an average of 187 kL per connection,
down 10% from 2018/19.

3.6 Our Demand The maximum daily demand for potable water in 2020/21 year was 8.8 ML in Innisfail, 7.4 ML in Tully,

The maximum daily demands as indicated above represent:

68% of the Tully maximum daily allocation limit from Boulder Creek and Bulgun Creek;
38% of the Cardwell (Meunga Creek) maximum daily allocation limit; and
23% of the combined Nyleta Creek, South Liverpool Creek maximum daily allocation limit plus the
capacity of the Jurs Creek bore.
3.7 Our Allocation Cassowary Coast Regional Council is authorised to take water and/or impound water at the various
sources. The table below list all of Councils current allocations.
Innisfail has the largest allocation with 3410 ML per annum and a maximum day demand of 20.4 ML.
In the Tully Scheme (Bulgun and Boulder) the total annual allocations for both creeks combined is
2764ML with a maximum of maximum day demand of 10.95ML/day combined for both creeks.
The Nyleta scheme is supplied from 3 sources, Nyleta Creek, South Liverpool Creek and Jurs Creek
Bore. The total allocation from all sources is 2596 ML and a maximum day demand of 15.1 ML.
Cardwell is CCRC’s smallest scheme with 1400 ML per annum and a maximum day demand of 5.6 ML.
The available spare maximum daily allocation for the Tully Schemes is a long term issue that needs
further investigation. To some extent, the spare capacity in the Nyleta scheme can supplement the
overall Mission Beach regional demand by drawing water from Nyleta into the Tully Scheme through
the 250mm diameter inter-connection of the Tully and Nyleta scheme near Mission Circle off Tully-
Mission Beach Rd.

The maximum daily allocation limit granted by DRDMW for South Liverpool Creek is 10ML/day. This
allocation significantly improves the water security for both the Nyleta and Tully Schemes. The inter-
connection of the Nyleta and Tully Schemes along Tully-Mission Beach Rd, between Mission Circle and
Stephens St and was completed in 2015-16. This allows flow to be directed from the Nyleta Scheme
(including South Liverpool Creek) into the Tully Scheme and vice versa.
A larger issue across the region is the lack of water security during periods of sustained drought. The
flow in all of Council’s creek and river supplies are highly susceptible to sustained dry weather. Water
restrictions are required in all schemes in the months prior to the commencement of the monsoonal
system. It is not uncommon for level 3 restrictions to be required.

3.8 Asset Performance - Water
3.8.1 Length of Mains
Of the 814 km of water mains in the Cassowary Coast Regional Council area, the Tully Scheme has the
highest representation followed closely by the Innisfail Scheme. The Cardwell Scheme has the smallest
length of water main.
Figure 15. Length of Water Mains
3.8.2 Network Density
Proportionally the density of population supported by the water reticulation network is quite sparse.
As can be seen from the water reticulation network maps, all schemes have extensive networks
servicing rural areas with very low levels of population. By contrast, most other large water authorities
in Queensland have network densities of over 100 people per km of water main.

3.8.3 Water Main Breaks
Water main breaks per 100 km of water main are an indication of how reliable a water service is.
Details of water main breaks are collated each year and are used in the development of the water
mains renewal program.
Figure 17. Breaks per 100km of Water Main
This information is particularly vital for AC and polyethylene mains which have highly variable failure
histories depending on factors such as installation practices, operating pressures and ground water
levels.

Class 12 white pvc had been used quite extensively in the region between 1990 and 2000. System
pressures in the southern region can exceed 100m without pressure regulation and it is believed that
many of the failures of the "white" pvc pipe result from accelerated fatigue of the pipe material due
to high pressures. Pressure regulating valves are now installed in most high-pressure zones but most
of the damage is believed to have accumulated prior to the installation of the pressure regulation.
Other problems that are causing problems with the network are the standard of bedding and backfill
that was used in many installations. During repair activities, it is commonly noted that the existing

pipes were not bedded in sand and hence are susceptible to damage and failure from external
abrasion damage or point loadings.
High water tables have also been observed to be impacting the condition of asbestos cement pipes.
The ground water in much of the region is very soft and continued exposure weakens the cement
matrix of the pipes. This softening of the pipe combined with high pressures has been observed to be
a cause for a number of failures of asbestos cement pipes.
The Tully Scheme had the highest with 30.85 breaks per 100 km of water mains followed by Cardwell,
15.91, and Nyleta, 13.58. These schemes have a large amount of pipeline installed in rural areas where
there is greater evidence of poor installation practices and where the pipes were operating for many
years under high pressures. In the Tully Scheme, of the 300 km of pipe, approximately 50% is class 12
pvc and approximately 20% is asbestos cement. The former pipe material has issues with fatigue
failures and the latter has issues with softening due to high ground water levels.
There were 92 mains breaks in the Tully Scheme area and our records show that 50% of all breaks
occurred on rural mains with low numbers of serviced properties and with very poor rates of return.
In the last 3 years there has been a surge in breaks in Tully, representing an accelerating in the
deterioration of the already fatigued and ageing assets.
In the Innisfail Scheme with 18.28 breaks per 100km of pipe, with a significant increase of breaks on
the 300 AC supply main in Belvedere.
Data on water main breaks and leaks that occurred in 2020/21 are detailed in Appendix D.
Factors of particular concern are:
The continuing failure of the rubber rings in the 300mm supply main from Stoters Hill
Reservoir into Innisfail is a significant challenge. Aside from the jointing rings the condition of
the pipe is sound. To date all failures have been in the section from the reservoir to the Bruce
Highway but this circa 1968 main extends from Stoters Reservoir through to the Jubilee Bridge
in Innisfail. Investigations are continuing on the future installation of an internal thin walled
polyethylene liner.
Council is observing a high proportion of failures of polyethylene pipe in the reticulation
network and in service lines. Recently the polyethylene pipe manufacturers association
provided literature that recommended against the use of polyethylene pipe where its life
expectancy could be reduced by a combination of high chlorine levels, high ground
temperatures and moderate to high working pressures. These factors are prevalent in many
parts of Council’s network. The introduction of additional pressure control devices in the
network is crucial if Council is to be successful in limiting the extent of failures of its
polyethylene pipe assets.
Significant numbers of failures of rural mains with limited connections. Many of these mains
have been gifted to Council as assets from farmers. In most situations poor installation
practices are the direct cause of many of the failures.

3.8.4 Water Losses
Real water loss is the difference between the water supplied and water accounted for. Water lost
includes leakage from mains and burst mains, water used in fire fighting, illegal use of non Council
standpipes and errors with water meters (reading low). Water used in flushing programs is not
included as "lost water" as it is accounted for with metered standpipes.
In terms of losses, the Innisfail Scheme is subject to the highest water loss per km of water main per
day. The rollout of the smart meter program in Wangan, Mundoo, Innisfail Estate and Cullinane during
the last year and a half is starting to have an effect on real losses. With real loses dropping from 12.0
to 8.4 kL/km.
Cardwell, traditionally the best performing scheme, is starting to trend upwards with real losses
increasing by 30% in the last two years. Consideration should be given to implementing the smart
meter rollout program in Cardwell to reduce the loss of water from unreading or faulty meters.
Figure 18.Real Water Losses kL/km off Water Main
The volumes of unaccounted water are a significant concern and substantial effort and funding should
be directed to improving this outcome.
The loss in the Innisfail Scheme is a particular concern as all reticulated water in this scheme is fully
treated and pumped on multiple occasions.
3.9 Water Loss Management Strategy
3.9.1 Water Loss Management Plan
In 2019 a water loss management plan was prepared to formalise a strategic response to the reduce
water losses from the reticulated network. This plan outlines a number of capital and operational
programs that should be implemented over the coming years to provide significant and permanent
reductions in the proportion of calculated annual real losses and unavoidable annual real losses of
water.

Strategies for improvements in demand management and reduction in system losses are funded in
the 10-year plan including:
Leakage detection program;
Continued deployment of smart metering and more in system metering to be able to locate
leaks in the system faster;
Accelerated replacement of aging meter fleet;
Replacement of commercial meters with combined fire/domestic uses;
Pressure management of high-pressure zones;
Increased funding for replacement program of aging or problem mains;
SCADA communications and data management systems which enable real time monitoring of
flow rates and pressures in the network.
During 2020/2021 several key programs have been implemented, these include:
Construction of the pressure reducing valve at Spannagle Rd, Pingin Hill
Installation of the active pressure control at Clump Mt Booster Pumps and Bulgun Chlorinator
In the coming year/s further programs will be implemented to reduce leakage and continuously
improve the asset base. These programs include the maintenance of calibration of bulk meters,
identify and replace suspect customer meters, active leak detection by field investigation and
continued development of district metered areas and pressure zones.

3.10 Financial Performance - Water
3.10.1 Operating Costs
Operating costs for water have increased in comparison to 2019/20 across all water schemes. The
largest increase has been in the Tully water scheme. Depreciation costs have increased since 2019/20
due to the completion of major capital items of Wheatley’s Hill reservoir and with the completion of
Bulgun reservoir. The operating costs figures below are inclusive of operational and maintenance
expenses, rates, insurance and internal charges for support to the Water business unit.

3.10.2 Capital Works
Capital expenditure in 2020/21 was $4.57M, down from $9.97M in the previous year. This significant
drop in expenditure comes from the completion of the Wheatleys Reservoir and Bulgun Reservoir.
Significant elements in the 2020/21 capital funding program included:
Funding of $1.9M for replacement of aging mains in each of the schemes
Funding of $1.0M for construction of the new reservoir at Bulgun Creek and associated assets.
Funding of $0.55M for Water Meter & Service renewal

Total revenue has increased compared to 2019/20. The largest percentage increases are in the
Cardwell (7.0%) and Innisfail (6.6%) schemes. The overall increase is approximately 5.2%. The
increase in revenue has helped offset the increase on the expenditure side.
3.10.5 Financial Sustainability
The overall financial performance of each water supply scheme is represented by the calculation of
the economic rate of return (ERR) for each scheme as summarised below (FN17):
Water
Scheme
Overall Cardwell

Table 9 Economic Rate of Return by Scheme (Water)
Note: Where ERR = Revenue from water business operations less operating expenses (operation,
maintenance and administration expenses (OMA) + current cost depreciation) for the water business
divided by written down replacement cost (WDRC) of operational assets for the water business.
The overall rate of return has increase slightly across all schemes, but there has been significant
individual increases in Cardwell and Innisfail offsetting decreases in Tully and Nyleta.
The Tully and Nyleta schemes have been impacted by an increase in operational and depreciation
expenditure greater than the corresponding increase in revenue. The rate of return for Tully will
continue to reduce in future years now that the reservoirs at Wheatleys Hill and Bulgun Ck intake are
capitalised and being depreciated.
In 2020/21 water consumption charges across the shire were normalised. This has resulted in an
increase in revenue in Cardwell and Tully. This was necessary given the forecast for declining rates of
return.
Council should also give consideration to the options to improve the rate of return from parts of the
rural networks. In many instances Council is paying substantial depreciation and maintenance costs
for water main assets with few connected properties. Records are being gathered of uneconomical
service areas and it is anticipated this issue will be elevated to Council for further consideration.
Options could include higher charges regimes in some areas, changes to renewal strategies (insertion
of polyethylene mains inside the host pipe) or possibly changing the water serviced area (no provision
of water to some customers in uneconomic areas). For this latter option, some compensation would
43
be payable to allow the consumers to install alternative supply systems such as rainwater tanks.
Potentially this compensation could be $10,000 to $15,000 per connection. Budgets would need to
be developed for this strategy.
3.10.6 Funding for Water Assets
In June 2019, Council adopted the Water Asset Management Plan (AMP) which outlined the funding
requirements of the next ten years to meet the pending renewal of water assets that are reaching
their theoretical asset life. The age profile of water assets is shown below. Aside from the Innisfail
treatment plant and network reservoirs, the major cost elements of these asset values are water
mains.
Figure 19. Value of water assets installed on date basis
The majority of water mains before mid 1950’s was predominantly cast iron (CI). Many of these CI
assets were unlined (without a cement lining). The CI mains in Innisfail were predominantly installed
in the 1930’s. The CI mains in Tully were mainly installed in the 1940’s. Unlined CI suffers from
extensive internal ferric corrosion which causes pitting to the iron and the ferric nodules can seriously
impact the flow capacity of the pipe. Council has adopted a useful life of 80 years for its cast iron
water mains so much of the CI network has already exceeded the theoretical useful life. A renewal
program is underway in Innisfail and Tully to replace these unlined CI mains.
From the mid 1950’s to the early 1980’s the predominant pipe material was asbestos cement. The life
expectancy of asbestos cement is highly variable and is dependent on the water table depth, water
alkalinity and pH, pressure conditions and installation practices. Council has adopted an asset life for
44
AC pipes of 60 years so the large sections of the AC network installed in the 1950’s and 60’s are now
nearing the end of their useful life. A portion of the current water mains renewal budget is being
allocated to replace aging AC mains but particularly the mains with a history of failures.
The majority of pipes installed in the 1990’s was class 12 “white” pvc. Unfortunately, this type of pipe
has shown to be particularly susceptible to fatigue failure from pressure pulses and these sections of
pipe must be carefully pressure regulated otherwise they fail well before the end of their useful life.
The white pvc Mission beach trunk supply main on Tully Mission Beach Rd was replaced in 2013
because of repeated occurrences of this failure mechanism. White pvc has been given a
recommended useful life of 50 years which should see the majority of these assets renewed in about
30 years.
Since about the year 2000, Council has been using either ductile iron cement lined pipes or class 16
modified PVC (Mpvc). These assets have a recommended useful life of 80 years.
The AMP contains an overview of renewal funding going forward until 2039. Refer graph below. The
renewal funding requirements in the next 20 years are largely related to water main renewals as these
assets reach the end of their nominal useful life. Separate work on water main renewals has identified
that theoretically Council has a water mains renewal funding requirement of $77 million between
2019 and 2032. This would require a smoothed renewal funding commitment of a minimum of $5.5
million per year. In 2020/21 Council committed $2.68M for water main renewals and in 2021/22, it is
anticipated Council will commit a similar amount. This relatively low level of renewal funding is being
constrained by the need to fund major capital works such as the new reservoirs at Wheatleys Hill,
Bulgun Intake, Cardwell Intake and Hyatt St over the next 5 years. New infrastructure is identified as
“Acquisition” in the graph below.
Figure 20. Water expenditure profile for 20 year horizon
45
The requirement for water mains renewal funding will be a challenge for budgets going forward and
Council will need to be innovative with renewal technology and construction methods to minimise the
renewal expense. Council will also need to increase its focus on measures such as pressure
management to extend the working life of its assets.
3.11 Customer Service Performance - Water
3.11.1 General
Council has a customer request (CR) system where customers notify Council of specific issues such as
faulty meters, leaking water services, leaking water mains, water quality issues (turbidity or taste),
lack of pressure, lack of flow and other miscellaneous matters. Upon notification of the issue, Council
staff respond to the issue and either rectify the problem immediately or in other cases, program for
planned work. Details of all responses to customer requests are compiled by the responding officer
within Council's Technology One Data base system.
A summary of complaints gathered in all scheme areas is provided in Appendix B. The type of
complaints and numbers of complainants is summarised below.

Table 10 Water Quality Complaints by Scheme
Many of the water quality complaints in Innisfail relate to loss of water pressure or dirty water
following mains breaks. Dirty water is usually the result of dislodgement of materials from cast iron
pipes or lack of flushing from end of mains.
A noticeable reduction in dirty water complaints in the Tully scheme, 16 down from 31 in 2019/20 is
a result of the Bulgun Intake Reservoir coming online in December 2020.

Table 11 Water Service Complaints by Scheme
The Nyleta and Tully Schemes are more highly represented in this data. A number of factors are
involved:
The system pressures in the Nyleta and Tully Schemes are typically higher than other schemes
resulting in more leakage at service connections.
There is more problem pipe material (class 12 pvc) in the Tully Scheme than other schemes.
The average age of meters in the Tully Scheme is higher than other schemes.
The meter replacement programme and associated renewal work on service connections being undertaken in Innisfail has resulted in a reduction of water service complaints, 25 down from 51 in 2019/20.

Table 12 Water Incidents Response Time by Scheme
For repair works, this response time reflects when staff arrive to the site to undertake the repair.
Typically, on initial receipt of the customer request there is an assessment by the Supervisor about
the criticality of the issue and the repair is prioritised according to the workload of the operational
teams. Details outlined in the response time commentary in Appendix C clearly indicate the majority
of delayed responses relate to low priority repairs where there has been either no loss of supply or a
minor loss of pressure that did not affect supply.
Taking into account these factors, the operational team are providing an acceptable level of service to
main break and leaks. Further discussion on this issue is in the data for Customer Service Standards.
Council is currently not processing average response times to service breaks or leaks. Until staff have
an automated data entry system that allows easy extraction of time statistics, the calculation of
response times is beyond current resources levels. However, notwithstanding that the customer
request data for service repairs times is not being assessed, the Supervisors prioritise service repairs
47
in the same manner as water mains and a loss of supply is always treated as an urgent response even
on weekends. It is quite reasonable to assume response times for service issues are better than the
data above for mains breaks/leaks.
Appendix C provided data on response time outliers which affected the response time calculations for
all schemes.
3.11.5 Staffing Levels per Scheme Area
Council’s ability to recruit and retain skilled plumbers in 2020/21 has been very low. For the majority
of the year both the North and South reticulation teams have been down one or two plumbers. This
has resulted in a reduced capacity to deliver services.
Water reticulation staff are allocated to teams being either capital or operational. Capital staff are
largely occupied with the water mains renewal program. Operational staff are responsible for mains
breaks, service breaks and general maintenance.
Operational reticulation staff are also responsible for the valve and the hydrant maintenance program
in each area and this is also a significant work load.
The deployment of smart metering is now largely being undertaken by contract plumbers under the
supervision of a Council plumber nominally based at Tully. Operational maintenance of existing smart
meters is undertaken by a Council plumber (higher duties). As the numbers of smart meters increases,
it is envisaged that an additional plumber will need to be engaged to assist with the smart meter
maintenance activities.

4.3 Capital Works Projects 2020/21
4.3.1 Sewer Rehabilitation Program
During 2020-21 Council continued the program to rehabilitate deteriorated gravity sewers using the
relining process in the Innisfail and Tully sewer schemes. The original, predominantly earthenware,
pipes are prone to cracking, root ingress, dislocation and failure of the rubber sealing rings allowing
ground water ingress into our sewer collection systems. The current relining process involves forming
a new PVC sewer pipe inside the original pipe. The as-new pipe is structurally rigid and involves
minimal disturbance to properties.
All water in the sewer network must be pumped (sometimes multiple times) and treated at high cost.
The Sewer Rehabilitation program aims to improve operational efficiency by reduction in pumping
and treatment costs, reduced blockages and extending the sewer usable asset life.

4.3.2 SPS 03 Valve Pit and Dry Well Rearrangement
One of the major projects finalised during 2020-21 was the construction of a new valve pit at sewerage
pump station #03 in Innisfail. The pump station had previously been identified as hazardous zone by
operators. The purpose of this project was to bring the valves into a pit external to the dry well,
making them more accessible for maintenance and allowing for the future conversion of the wet/dry
configuration into a solely wet well configuration.
As part of the design process a 3-dimensional scan was undertaken of the existing dry well pipework.
ARUP Consulting who was responsible for detailed design was able to produce a 3D model of the final
design that allowed maintenance personnel to review the proposed solution prior to construction.
The construction work was undertaken Celtic Construction & Utility Services.
A 3.3m by 2.9m reinforced concrete pit was constructed on the western side of the existing dry well
and new air, non-return and isolation valves fitted. Each pump was then rotated on its plinth 180
degrees and the pump discharge relocated to the outside edge of the dry well.
The relocation of the non-return valves from a vertical position to a horizontal installation has resulted
in marked improvement in the operation of the pump station and rising main. Other benefits also
include the reduction in rags blocking the non-return valves minimising the drainage of the rising main
back into the wet well.
Figure 22. SPS3 Dry Well Reconfiguration

4.3.3 NMB1 and WB3 Flow Meter Pits
As part of the general improvement works at sewage pump stations in the Tully Mission Beach
Sewerage scheme, flow meters were installed at both North Mission Beach #1 (NMB1) and Wongaling
Beach #3 (WB3) sewerage pump stations.
The flow meters improve data collection and operation of the Mission Beach sewerage scheme by
enabling real time flow data to be collected and monitored. Both NMB1 and WB3 pump directly to
the Mission Beach Main Transfer Station and the measurement of flow enables improved
understanding of the sewage flows in the Mission Beach area.
By collecting flow data, diurnal flow curves can be developed enabling operators to identify blockages,
pump decline and also determine the impact of infiltration and inflow of the network.
Both flow meter pits at NMB1 and WB3 were designed in house by the Cassowary Coast Regional
Council design team. Construction was undertaken by Celtic Construction and Utility Services.

4.3.4 Geraldton Bridge Sewer Rising Main Renewal
The sewerage rising main from SPS25 connecting Innisfail Estate to Innisfail via Geraldton Bridge was
replaced following a condition assessment in which significant corrosion was identified.
Similar to the corrosion failure of the SPS3 rising main, the condition assessment identified an erosion
of the concrete lining of DICL pipe along invert of the pipe exposing the ductile iron to corrosion. The
resulting corrosion of the ductile iron led to failure of the integrity of the pipe. Fortunately, the
operating pressure of the rising main is very low allowing the use of “wang clamps” to provide
temporary repairs.
170 meters of polyurethane lined ductile iron pipe was installed over the course of three nights to
minimise the disruption of traffic on Geraldton Bridge. The polyurethane lining is design to give
greater resistance to Hydrogen Sulphide gasses found is sewerage.
4.3.5 Innisfail STP Ultra Violet Transmissivity
The Innisfail Waste Water Treatment Plant uses Ultra Violet light to deactivate potentially harmful
pathogens in effluent water before re-entering the environment. The UVT analyser measures
intensity of the UV light allowing for a reduction in power costs while maintaining effectiveness.
54
4.3.6 SPS14
Refurbishment of Innisfail Sewer Pump Station SPS13 and SPS14 has been undertaken to extend the
life of the existing assets and improve safety, access and efficiency. The stations had remained almost
unchanged since construction. Works undertaken at each pump station renewal included upgrading
the switchboard with enhanced SCADA, new pump, new pipework, relining of the well and new pump
station cover.
Figure 25. SPS14 Recoating of wet well
4.3.7 Planning and Design Activities
Design has continued with the replacement of the motor control centre (MCC) at the Tully STP.
Documentation has now been completed for a blockwork structure with elevated floor to replace the
existing prefabricated enclosure. Switchboard design work has also been completed. Construction of
the MCC building and electrical upgrades are scheduled for 2021.
Forward investigation and design activities concentrated on known problems areas within the sewer
reticulation network. Investigations into sewer overflows at Bliss St Innisfail, Paul St Cullinane and
Bon Villa Ave Belvedere have produced designs to be funded and constructed in the 2021/22 program.
Overflow issues at Bineham St and Thurles St Tully are ongoing and require elevation to reduce the risk of repeated overflows at these locations.

4.4 Our Customers The majority of customers are serviced by the Innisfail sewerage scheme followed by Mission Beach
and Tully. Overall Cassowary Coast Regional Council supplies 14,974 customers with sewerage
services. There is very little growth in sewerage services in any of the service areas.

4.5 Our Treatment Cassowary Coast Regional Council treats 100% of the sewage received at the Sewage Treatment Plants
(STP) to a tertiary level. All sewage treated is discharged to either Ninds Creek in Innisfail or Banyan
Creek in Tully.
The Innisfail STP treats significantly more sewage than the Tully STP. Not only is this due to the higher
population but Innisfail also suffers greater problems with ground water infiltration into its network.
For the year 2020/21 Innisfail STP treated over 2,862 ML of sewage, while Tully STP treated 1,111 ML
of sewage. In total 3,973 ML was treated for the financial year which is up from 2,486 ML treated in
2019/20.
Figure 28. ML of Sewerage Treated
There is still a direct correlation between extreme rainfall and the treated flows of the treatment
plants. Very high rainfall in the Tully and Innisfail systems causes significant surface water infiltration
through overflow relief gullies and manholes. Ground water infiltration is gradually being improved
through the relining programs in Tully and Innisfail. Ground water infiltration from private house
drainage lines will continue to be an ongoing issue. At some point in the future, Council may have to
dedicate special operational funding to repairing failing private sewers where the owners are not
taking action to repair known faults.
During 2020/21, the maximum inflow into the Innisfail STP was 24.72 ML on the 5 January 2021. The
minimum flow for the year was 2.389 ML on the 20 December 2020, just 17 prior to the peak event

on the 5 January. The other significant peaking event occurred on ANZAC day, 25 April 2021, with 246
mm of rainfall recorded and 22.319 ML inflow into the plant. The average for October and November
2020 was 3.045 ML and represents the typical average dry weather flows (ADWF) into the Innisfail
STP.
The maximum inflow into the Tully STP for 2020/21 was 6.527 ML on the 18 February 2021. The
minimum flow was 0.728 ML on 19 December 2020. This represents a wet weather peaking of up to
9.0. During 2019/20. The average for October and November 2020 was 0.881 ML and represents the
typical average dry weather flows (ADWF) into the Tully STP. The Mission Beach catchment represents
approximately 40% of total inflow into the Tully STP depending on rainfall.
The majority of sewage is residential and non trade waste. Trade waste, including septic, makes up a
small portion of sewage but is higher strength than residential sewage. This requires higher
operational monitoring to ensure that CCRC doesn’t breach its environmental licence conditions.

The Innisfail STP treated 820 kL per connection in the 2020/21 financial year compared to the Tully
STP of 814 kL per connection. This is the first time there is some parity between the two schemes for
the volume treated per connection and highlights that the sewer relining program is having an effect
on sewer infiltration.
4.6 Asset Performance - Sewerage
4.6.1 Length of Mains
Of the 229 km of sewerage main throughout the Cassowary Coast Regional Council, 107.4 km is in
Innisfail, 85.7 km is in Mission Beach and 37.8 km is in Tully2.
Figure 31. Length of Mains (km) by Scheme
4.6.2 Mains Breaks or Chokes
Sewer main breaks/chokes are caused by a number of things including poor maintenance, disposable
wipes, fat and grease build up, ageing sewer pipe and tree root penetration. Tully has the least number
of chokes per 100 km of sewer main followed by Innisfail and Mission Beach.
The increase in incidents in Mission beach is concerning as this is the newest sewer in the region and
to date has performed well. An increase in jump dislocation has contributed to this increase.

4.6.3 Biosolids
The current biosolids removal contractor for the Tully and Innisfail STP's is Arkwood. Approximately
930 and 1,512 of biosolids were exported from Tully STP and the Innisfail STP respectively at a total
cost of $185,500, up 3% on 2019/20 . Depending on weather conditions, biosolids are used on
agricultural properties for beneficial improvement of the soil.
4.7 Financial Performance - Sewerage
4.7.1 Operating Costs
Operating and depreciation costs for sewerage increased slightly from $8.33M in 2019/20 to $8.47M
in 2020/21. Overall, there is an increase in expenditure for the Sewerage Program of $140K. Innisfail
and Mission Beach schemes have increased offset by a small reduction in the Tully Scheme. Operating

costs are inclusive of operational and maintenance expenses, rates, insurance and internal charges for
IT and other section support to Sewerage business unit.
The overall increase in Water depreciation is due to the revaluation undertaken at the end of the
19/20 financial year with the largest increase in Tully Water Reticulation (water mains). Depreciation
has also increased for Reservoir assets due to completion of Wheatleys Hill (full year depreciation)
and Bulgun Reservoirs (part year depreciation).
There has been a reduction in Sewerage depreciation, mainly in Tully Sewer Mains as there was a
change in methodology of valuing the Tully MB Rising Main asset by splitting the asset into trench and
pipe assets, resulting in lower depreciation.

2020/21 capital funding program included:
$1M for relining of gravity sewers in Innisfail and Tully;
$270K for the SPS 3 Valve Pit;
$185K for Sewer Pump Stations;

Table 17 Revenue by Scheme (Sewerage)
4.7.5 Financial Sustainability
The overall financial performance of each sewerage scheme is represented by the calculation of the
economic rate of return for each scheme as summarised below:
Sewerage Scheme Overall Innisfail Mission Beach Tully
ERR 2020/21 (%) 1.08 0.94 1.30 1.05
ERR 2019/20 (%) 1.25 1.39 0.24 2.97
ERR 2018/19 (%) 1.45 2.06 -0.01 3.07
Table 18 Economic Rate of Return by Scheme (Sewerage)
Note: Where ERR= Revenue from water business operations less operating expenses (operation,
maintenance and administration expenses (OMA) + current cost depreciation) for the sewerage
business divided by written down replacement cost (WDRC) of operational assets for the sewerage
business.
In simple terms, the ERR is a percentage return on the written down replacement costs of the assets.
A zero ERR is break even.
These calculations show that the revenue stream from sewerage charges is just sufficient to ensure a
positive rate of return on the value of the assets.
An increase in operating costs ($770) combined with a reduction in revenue ($130K) has contributed
to the reduction in the ERR . An increase in chemical usage due to the extended wet season coupled
with increases across the board in chemical prices has resulted in higher operating costs. The Tully
STP (14 years) and the Innisfail STP (9 years) are aging plants. It is expected to see an increase in
62
operation and maintenance issues around electrical and mechanical items as they approach their end
of life.
Each of these treatment plants and the reticulation system at Mission Beach has capacity for
populations well in excess of current connections and the depreciation and borrowings costs of these
facilities is currently being borne by a comparatively small population. (It should be noted that interest
payments are excluded in the ERR calculation.)
Strategies (with associated capital funding) have been developed, which will have some moderate
impact on the operational cost of the sewerage schemes. Relevant strategies include the relining
program to reduce ground water infiltration and the improvement of overflow facilities at key pump
stations. These works will reduce pumping costs and treatment costs which will have some modest
impact on operational expenses for electricity and chemical consumption.
A review of benchmark data of the sewerage charges of other authorities indicates that CCRC
sewerage charges are some of the highest in the State. Sewerage charges are unlikely to fall in the
near future without significant increases in the population base.
4.7.6 Funding for Sewerage Assets
In June 2019, Council adopted the Sewerage Asset Management Plan (AMP) which outlined the
funding requirements of the next ten years to meet the pending renewal of sewerage assets that are
reaching their theoretical asset life. A revaluation of sewerage assets was completed in 2020 and the
updated data from this revaluation has since been reflected in minor modifications to the sewerage
AMP.
The anticipated accumulated renewal budget for the next 10 years is $19.2 (or smoothed, $1.9million
per year). Council is currently committing sufficient funds to meet this renewal cost requirement.
Significant capital upgrades and new works are in the process of being undertaken at the Tully
Sewerage Treatment Plant (2020-2025) including the construction of a new clarifier, the upgrade of
the motor control centre, a new control building and a major upgrade to the inlet works with new grit
removal facility.
The graph below shows the forecast funding requirements until 2039.

4.8 Customer Service Performance - Sewerage Council has a customer request (CR) system where customers notify Council of specific issues such as
odours, blockages, sewerage overflows. Upon notification of the issue, Council staff respond to the
issue and either rectify the problem immediately or in other cases, programme for planned work.
Details of all responses to customer requests are compiled by the responding officer on a water
activity form and details are input into Council's Technology One Data base system.

5 OUR CUSTOMER SERVICE STANDARDS
5.1 Changes to the Customer Service Standards Council reviewed the Customer Service Charter in 2020/21 as part of the overall review of the
DWQMP. The revised Customer Service Charter was endorsed by Council in February 2021.
The Customer Service Charter outlines Council's agreed obligations for water and sewerage services
to its customers. The Customer Charter documents customer service standards, the process for
service connections, billing, metering, accounting, customer consultation, complaints and dispute
resolution. The Charter also includes obligations of customers when they agree to take our services.
In addition to some minor wording amendments the significant changes to the CSS where the inclusion
of the Backflow Prevention and AMR Meters (smart meters).
The Backflow Prevention policy adopted by Council requires property owners with testable devices
to be tested and registered with Council in accordance with State Legislation. The CSS reminds
property owners of this obligation.
AMR Meters (smart meters) now account for almost 50% of the total water meter fleet. Council will
provide limited advice to a customer with a Smart Meter if a leak greater than 20L per hour is detected
by the AMR. Council accepts no responsibility for non-notification of leaks where data is inadequate.
The CSS reminds property owners that they are responsible for all water consumption read by the
water meter.
Commentary on the performance against the target CSS is included in the notes.

Notes:
1. As in previous years, the Tully Scheme suffers the largest numbers of mains breaks. The Tully area has high operating pressures, significant class 12 pvc
and evidence of historically poor installation practices.

2. This indicator is calculated by dividing the total number of mains breaks/leaks per 1000 connections.
3. Average response times for mains breaks is typically significantly less than 5 hours. As mains breaks are treated as a priority, the response times are
short.
4. The collection and recording of data for this indicator requires further investigation to reduce skewing of results by mis-recording of data. Restoration of
customer services is actioned as a priority.
5. The volume of water lost per connection per day is well outside the target range for all schemes and there has not been much improvement with this
indicator over the past couple of years. This report documents strategies underway to reduce the amount of unaccounted for water
6. Numbers of water quality complaints were within targets for all regions. The new Bulgun Ck intake reservoir has had a major impact to this indicator in
Tully.
7. Refer DWQMP Report Water Quality Incidents. High turbidity events triggered 8 boil water alerts in the Tully scheme area. Council’s water quality testing
program confirmed there were no ecoli detections in any scheme during the year.
8. Numbers of sewerage chokes or breaks were well within targets. An increase in blockages is noted in Tully.
9. A significant improvement in this indictor for the 20/21 period.

6 DWQMP Report - Review of Compliance with our DWQMP
6.1 DWQMP REPORT Pursuant to sections 141 and 142 of the Water Supply (Safety and Reliability), a DWQMP Report must
be prepared for each financial year and must be given to the Regulator within 120 days after the end
of the financial year to which it relates. The report assists the Regulator to determine whether the
approved DWQMP and any approval conditions have been complied with and provides a mechanism
for providers to report publicly on their performance in managing drinking water quality.
6.2 Background One of the major water quality challenges still facing Council is the management of turbidity with its
run of the creek systems following periods of heavy rainfall. Each of the run of the creek intakes for
the Nyleta, Tully and Cardwell Schemes are susceptible to these turbidity events. The DWQMP
Improvement Plan includes a number of strategies to better manage the impact of turbidity. A copy
of the DWQMP Improvement Plan with comments on the status of the improvements is included in
Appendix D:
Council has now completed several key initiatives to improve water quality across the Nyleta, Tully
and Cardwell Schemes as outlined below.
Nyleta Scheme: Construction of a new 3.3ML reservoir and a new sub-bed filtered intake on South
Liverpool Ck were completed in late 2017. The reservoir has sufficient storage for a minimum of 24
hours without any inflow. This new intake will filter turbid source water and allow water to be drawn
from South Liverpool Ck and pumped to the new reservoir. No boil water events have occurred since
completion.
Tully Scheme: Construction was completed in October 2020 for a new intake reservoir near the Bulgun
Ck intake. This has allowed the intake sources (Bulgun Ck and Boulder Ck) to be isolated during periods
of high turbidity. Since the completion of this reservoir no boil events have occurred in the scheme.
In December 2019, Council completed construction of additional network storage at the Wheatleys
Hill site. Valving and procedures have been implemented to isolate the South Mission Beach area
during periods of high turbidity with this area relying on reservoir storage and if needed additional
supply from the Jurs Ck bore or the Nyleta Ck source via North Mission Beach and the scheme
interconnection at Mission Circle.
Bulgun Creek Intake Reservoir was completed in November 2020. This reservoir has sufficient storage
for 24 hours without inflow. During periods of high turbidity in Bulgun and/or Boulder creek the
system will be supplied from this reservoir until the turbidity drops and clean water can be once again
be supplied from the creek. This system is fully automated and can be controlled remotely by the
operator via SCADA.
71
Hyatts street high level reservoir, another key initiative for the mitigation of turbidity in the source
water is on schedule to be completed in 2023/24.
Cardwell Scheme: During periods of high turbidity in Meunga Ck, the intake is isolated and the
Cardwell region supplied by existing storage capacity in the reservoir supplemented with flow from
Kennedy Bore. Works have proven highly effective at avoiding the need to implement boil water
notices to the Cardwell Scheme. Planning has continued for a reservoir at the Cardwell intake and
negotiations are well advanced to secure a lease from the National Park.
6.3 Review of DWQMP In November 2020 Council submitted an application for amendment to the Drinking Water Quality
Management Plan. The amendment was required as CCRC has made significant progress in addressing
water quality issues in the Nyleta, Cardwell and Tully schemes through the construction of several new
assets.
The new assets that were included in the amendment are the Bulgun Intake Reservoir (and associated
control systems), Wheatlys Reservoir and Clump Mountain pump station as well as some minor
corrections to the existing asset base.
The review also updated the Risk Improvement Plan, the Sampling Manual, Quality Control Plan and
Incident Response plans.
The Risk Improvement Plan was updated to reflect the findings from the Viridis HBT assessment and
the DWQMP Audit by Dan Deere, discussed below.
The testing of disinfection by-products is now included in the sampling manual with testing for THM
and chlorates conducted in all schemes over a three months period once in the dry season and once
in the wet season
The amended DWQMP was accepted on the 26 July 2021.
6.4 Audit of DWQMP – April 2021 Two CCRC water supply systems, Tully Scheme and Cardwell Scheme, were audited in April 2021 to
assess Council’s compliance with its obligations under the Act, Regulations and Audit Guidelines. The
audit covered CCRC’s infrastructure, documents and records covered under the DWQMP as it
currently stands.
The audit was conducted on behalf of the Department of Regional Development, Manufacturing and
Water (DRDMW) by Dan Deere under the Water Supply (Safety and Reliability) Act 2008 (Qld). The
audit involved review of hard copy documentation, review of electronic records, interview with staff
and inspection of assets and systems.
The DWQMP, as amended, was found to be fully relevant, representing an accurate reflection of
CCRC’s infrastructure and the way in which it is operated. In summary, the auditor concluded that
CCRC’s DWQMP, as amended, was accurate, current and relevant.
72
A number of opportunities for improvement (OFIs) were identified during the audit. These OFIs have
been included in the DWQMP Risk Improvement Plan and will help CCRC improve efficiency, reliability
or reduce the risk of future non-compliances. These OFIs are summarised below.
Preparing for future revisions to guidelines and regulatory obligations that are likely to require
risks from protozoan pathogens to be explicitly assessed and appropriately mitigated. CCRC
can begin by sourcing evidence of groundwater security such as collecting raw water data on
E. coli, conductivity and turbidity and measuring the hydraulic response of the production
bore to rain events and assessing its connectivity to potential protozoan pathogen sources.
CCRC could define a well head protection zone and reliably protect that zone from protozoan
pathogen sources. (IP-56 Quality testing data for Kennedy bore not sufficient to designate as
a secure groundwater.)
Making a decision on the level of physical security required for its treated water storage
reservoirs and seeking to maintain protection at those levels. (IP-55 Improve security at some
Cardwell facilities)
Setting criteria for treated water storage reservoir integrity preventive measures to ensure
they act as barriers to the entry of ingress from vermin and runoff as far as reasonably
practicable. Undertake the works required to raise the standard of treated water storage
reservoir integrity preventive measures to reach or exceeded the agreed criteria. Embed safe
and practicable asset and/or operational management systems to inspect treated water
storage reservoirs and maintain and repair them in a preventive manner. (IP-55 Improve
security at some Cardwell facilities)
6.5 HBT Assessment A Health Based Target (HBT) assessment has been undertaken on two of CCRC’s water supply schemes,
Innisfail Scheme and Nyleta Scheme. The assessment is based on the Health Based Targets for
Drinking Water Safety published by Water Services Association of Australia (WSAA) to assess the
microbial safety of the scheme. Plus onsite inspections were conducted and guided by the Good
Practice Guide to the Operation of Drinking Water Supply Systems for the Management of Microbial
Risk published by WaterRA.
6.5.1 Nyleta Scheme
In early 2019, Viridis Consultants were engaged by DRDMW to undertake a health based target
assessment of the Nyleta Drinking Water Supply Scheme. Viridis completed their investigations in
June 2019 and their final report entitled Nyleta Health - Based Targets Assessment Detailed Report
was completed and provided to Council in August 2019. Key findings are:
The source water from Nyleta Ck was categorised in the assessment as Category 2. No
catchment improvements were identified. The source water from Liverpool Ck was identified
as Category 4 and the report made recommendations to allow the source waters to be
classified as Category 2. These works include temporary closure to the South Liverpool Ck
swimming hole during times of extraction and improvements to the septic facility at an
73
upstream unused scout hut. These matters have been presented to Council. The scout hut
septic has been pumped out and decommissioned. The gate isolating access to South
Liverpool Ck has not been installed. Council continues to monitor both creeks for ecoli. (IP-
54- Implement HBT actions for Nyleta CK / Sth Liverpool Ck source waters)
To meet HBT log reduction value requirements for Category 2 source water, ultra-violet light
disinfection systems need to be implemented in addition to the systems for turbidity
management and chlorination. Funding has been allowed in the nominal 10 year budgets for
these works. Funding has been allocated in the 21/22 capital budget to commence a planning
study.
In relation to the Jurs Ck bore, the source water was identified as Category 1. Some process
improvements were recommended including conductivity monitoring and on-line turbidity
instruments. These recommendations have not as yet been implemented. Flow performance
and maintenance issues at Jurs Ck bore has seen a reduced reliance on this asset in 2020/21.
Significant works are required to bring this asset to an acceptable standard.
6.5.2 Innisfail Scheme
In early 2020, Council engaged Viridis Consultants to undertake an HBT assessment of the Innisfail
scheme. Movement restrictions associated with covid delayed the completion of this report.
Viridis completed their investigations in November 2020 and their final report entitled Innisfail Health
- Based Targets Assessment Detailed Report was completed and provided to Council in December
2020. Key findings are:
The source water from Johnston River was categorised in the assessment as Category 3. No
catchment improvements were identified.
The assessment found that the Innisfail Water supply scheme has appropriate treatment and
protection against microbial pathogens if it is operated in accordance with good practice
guidelines. This requires changes to alert limits, critical limits and current automated shut
downs.
Review of the treatment plant results indicates that the plant is fit for purpose. However,
changes to operation are required to be within the appropriate protection zone of the safety
continuum. The assessment also demonstrates that for the protozoan risk there is no
redundancy in the system solely relying on filtration as the barrier for protection.
A number of improvement items were also identified to ensure ongoing performance or
improve consistency. Improvement items across the scheme, are:
o Continuing microbial indicator monitoring of raw water required (revisit this
assessment in twelve months to confirm the source water assessments when more
data is available)
o The plant should have online monitoring of pH before coagulation.
o Installation of additional turbidity instruments to improve operator’s ability to
diagnose and isolate filter performance issues. Additional turbidity instruments are
also required to confirm the LRV credits assigned to the filtration units.
74
o Improvement of stability of analysers (turbidity and free chlorine) as an enabler for
future automation
o Measures to improve filter start up and ripening (optimise to improve turbidity,
individual filter instrument, revise critical limits)
o Monitoring of media condition using inspections and head loss monitoring
Other minor improvements were also noted, such as a review of O&M manuals and the labelling of all
services in accordance with AS1345:1995.
6.6 Water Quality Test Data During 2020/21, Council undertook an extensive amount of water quality testing on the raw water
supply and in the network. The sampling and testing program are in accordance with the DWQMP
Appendix E - Sampling Manual. The summary of the testing program results for 2020/21 are included
in Appendix E. Comments are provided in the tabulated data for any exceedances of water quality
parameters. The testing data in Appendix E demonstrates a high level of water quality is being
maintained in all schemes with the exception of one boil water alert that impacted the Tully Scheme.
The boil water alert was triggered due to elevated turbidity in the source waters (Bulgun Creek intake
and Boulder Creek intake) and the associated reticulation network. Increased levels of water quality
testing are initiated as part of the DWQMP Quality Control Plan procedures when a boil water alert is
in effect. Boil water alerts are triggered when critical alert levels are reached for water quality
parameters as outlined in the DWQMP Quality Control Plan. Turbidity levels above 5NTU for more
than 4 hours at our primary chlorination points near our intakes is the primary factor triggering boil
water alerts.
No boil water alerts were initiated for the Innisfail, Nyleta and Cardwell schemes.
At this stage, Council is not testing for Cryptosporidium. The testing for this parasite is a high cost and
complex and currently beyond the resources of Council. There is some risk that Cryptosporidium may
exist in any of the untreated water supplies (Nyleta, Tully and Cardwell).
The advice provided to CCRC during the DWQMP Audit in April 2021 from Dan Deere was that due to
the nature of the catchment the risk of Cryptosporidium is very low and that installation of UV
disinfection on the Cardwell and Tully source water would not have significant benefits.

As discussed in the information for 2018/2019, below, it was hoped that the discoloured water
complaints in Tully would decrease markedly in 2020/21, after the new Bulgun Creek intake reservoir
is operational, that has now happened and the difference can be seen from the table above resulting
in a 50% reduction in “dirty” water complaints from 2019/20. Discoloured water complaints in Innisfail
largely relate to mains breaks.

On Friday morning of 12/3/21, Council was advised of a small bubbling leak adjoining a footpath next to Bamboo Creek off Charles St. Upon investigation it was confirmed that it was a minor leak from the 300mm DICL sewer rising main. The area was immediately isolated and work commenced to repair the pipe. All repairs were completed that day.

Lily Street
The other advices to DES through the pollution hotline system relate to failures of the 375mm diameter ductile iron cement lined sewer rising main from pump station 3 to pump station 1 in Innisfail. The pipe has been damaged by long term abrasion in the pipe invert.
Three failures have occurred in 2021. All failures have occurred during or immediately following periods of heavy rainfall when the pipeline is under increased pressure and the pumps are operating more frequently.
The cause of failure is consistent with abrasion/corrosion wear which forms as a 25mm wide groove along the invert of the ductile iron cement lined pipe.
In all incidents the release of sewerage was to kerb and channel in Lily street and then entered into the storm water system and out to the Johnston river. Sampling from the first incident indicated that the pollution was quickly diluted in the river causing minimal impact.
Council has implemented a programme to replace 122m of the rising main from SPS3 to the start of the river under bore in PE pipe. This will remove the last remaining section of DICL pipe from the SPS3 rising main. This work is expected to be finished by October 2021.

Council has invested in a design to relieve surcharging in the
sewer network by constructing a new sewer rising main from
the pump station in Cullinane Park to the gravity sewer
manhole on Anthony St near Campbell Street and upgrading
the gravity sewer line downstream of this manhole to the
pump station SPS12 in Fitzgerald Esplanade.

18/01/2021 Webb Crescent
Innisfail
No Yes Surcharging of manhole adjacent to lot 30 RP712813 on
Webb Crescent. The overflow incident on the 17/18
January 2021 followed a period of high rainfall that had
charged the water table (ground water infiltration). On
the 18 January, rainfall of 158mm was recorded in the
sewer catchment and a combination of these factors
would have contributed to significant surface water/
stormwater infiltration. For January 2021, total rainfall
up to and including the 18 January was 800mm.
Council still has lifted the overflow manhole approximately
500mm above the surrounding ground to minimise any
surface water ingress through the manhole lid and to limit
some of the overflow release at this location.
Survey and design activity has commenced for an
augmentation of an existing sewage overflow off Bliss St,

21/02/2021 4 Bineham St.
Tully
No No Surcharging of house drains at Lot 52 RP717793, 4
Bineham St Tully. On the evening of the Sunday 21
February 2021, the tenant at 4 Bineham St contacted
Council’s after hours call centre to advise that sewage
had entered her house.
The significant rainfall from the 17 February 2021 to the
time of the incident on the 21 February 2021 caused the
sewerage network to be full from ground water and
stormwater infiltration. The King St pump station was
under water though still operating. The pump station is
designed with an overflow such that when the pump
station is full, excess inflow is discharged to the adjoining
creek system. However due to localised creek flooding
the overflow was not able to function and hence the
sewage level in the upstream network was being
dictated by the high sewage levels in the pump station.
The next day (22/2/21) CCRC arranged for a cleaning
contracting company to clean the residence. The initial
cleaning was undertaken on 22/2/21 and a report from the
cleaning contractor of the extent of the sewage inundation
was received by Council on the evening of the 22/2/21.
CCRC on the 23/2/21 initiated the insurance claim and
negotiated further cleaning and temporary accommodation
for the tenant on the basis of a good faith response pending
the outcome of further investigations.
On the 24/02/21, Councils Plumbing Inspector undertook an
inspection of the premises to check the compliance of the
plumbing, particularly the overflow relief gully (ORG). The
inspection revealed that the ORG had been raised from the
time of the original construction and the new surface level of
the ORG was the same as the internal floor and internal floor
wastes. An ORG should be a minimum of 150mm below the
finished slab level to ensure any sewer pressure in the private
sewer system can release (overflow) to the external ground
level and not release inside the house.
Council’s sewerage system was full and surcharging prior to
and during the time of the incident due to the impact of
significant rainfall. Council’s sewerage system had been
designed to current design guidelines but the extent of
infiltration and minor flooding had caused the sewerage
network to back up and be under pressure. Due to the ORG at
83
4 Bineham St being at approximately the same level as the
internal floor wastes, sewage was released inside the
residence. If the ORG had been constructed to plumbing
standards the sewage release would most likely have been
confined to the externals of the house.
This matter is still the subject of an insurance claim against
CCRC.
19/05/2021 14 Thurles St
Tully
No No Surcharging of manhole at Lot 23 RP713781 on Thurles
Street. Several over incidents have occurred at this
location in previous years, all following or during heavy
rainfall events. The sewer at the rear of the property is
above ground and has been the source of some
frustration over many years (decades has been
suggested). The above ground sewer cross a creek
causing a localised flooding at the property.
Council has investigated the issues and can confirm that the
sewer is design in accordance with the relevant standards.
Council has initiated a survey of the area with the purpose to
investigate the possibility of realigning the sewer and remove
the above ground section from the property.

8 Conclusions
8.1 Conclusions
8.1.1 Water Operations
This performance report outlines the data collected for the Statewide Water Information
Management (SWIM) and provides commentary against many of the performance indicators
in the SWIM data and Council’s adopted Standards of Service. Information is also presented
that demonstrates Council’s activities comply with its approved Drinking Water Quality
Management Plan.
Performance against Standards of Service indicators suggests good outcomes in relation to
response times and restoration of service times for water mains breaks/ loss of service. High
levels of compliance are being achieved for water quality parameters. Total water mains
breaks per 100km of main is much higher than the nominated indicator and reflects
historically poor laying practices, deteriorated assets and high working pressures. Substantial
improvement is needed to reduce water losses to the nominated Standard of Service
indicator.
Council is meeting its regulatory obligations as a water service provider.
The network for each region is extensive and the network density (population served per km
of main) is low compared to most other large water authorities. The rate of return of many
rural mains is poor. Income from water charges in some rural areas does not adequately cover
operational costs and depreciation. Further investigation is needed across all schemes to
identify uneconomic mains and develop options to improve their rate of return. Options could
include inserting a smaller polyethylene main through the existing mains when these mains
reach the end of their serviceable life (this entails accepting a lower standard of fire-fighting
standard of service); decommissioning some mains or creating a different charge system to
better recover costs.
Mains breakages are more common in the Tully and Nyleta Schemes, which have extensive
rural distribution systems. Breakages can be correlated to poor installation practices, large
schemes with high pressures and usage of class 12 pvc pipe. Ongoing failures with the rubber
rings in the 300mm AC main from the Stoters Hill reservoir into Innisfail is a concern and
investigations are continuing on alternate lining methods to renew this asset.
The asset management plan for water assets has identified a substantial increase is needed
to fund the renewal program of cast iron and AC mains. Existing funding of approximately
$2.9 million for renewals will need to increase to about $5.5million. This increase will be
constrained by other significant capital requirements for reservoirs in the Tully and Cardwell.
In Innisfail and Tully the water mains renewal program is focusing on the replacement of cast
iron mains at the end of their asset life and which are suffering from internal ferric corrosion.
Mains replacements are being prioritised based on the connection type, fire flow demand and
function of the main.
85
Water losses are high in all schemes. Water loss is the difference between the water volume
that leaves the treatment plant / intake and the summation of all metered volumes from all
consumers, metered standpipes and metered auto-scourers. Unmetered water is typically
from main breakages, leaks, faulty property service meters and water theft. The water loss in
Innisfail is a particular concern as the lost water is fully treated and pumped.
Council has completed the replacement of water meters and installed automated meter
reading devices (smart meters) to Innisfail Estate, Wangan and South Johnston.
The financial position of the water operations is fair and improving with the increase to water
charges, particularly in the southern schemes. Council has undertaken substantive works to
improve water quality for all its run of the creek water supply schemes. The elimination of
the majority of boil water events due to the construction of turbidity monitoring, control
systems and reservoir storages will assist the case for an increase in water charges to the
southern regions.
Staffing levels servicing the Tully Scheme need to be increased to improve the response times
in that scheme, particularly in light of the poor condition of many of the assets.
The new 4.5 ML Bulgun Intake completed in November 2020 and has proven highly effective
in eliminating boil water events in the Tully Scheme.
Water main renewals have progressed in all scheme areas. In Innisfail and Tully the renewals
continue to focus on replacing the old cast iron mains with internal ferric corrosion. Covid 19
and the ability recruit and maintain staff levels has had a significant impact on the capital
works program.
Planning is continuing for an intake reservoir near Meunga Creek intake and applications have
been lodged for a lease from the National Park for the reservoir.
An audit of the DWQMP by Dan Deere was undertaken and undertook a health based target
assessment of the Innisfail supply scheme. Council is still awaiting the draft report.
Tan audit of the DWQMP was undertaken by Dan Deere. The DWQMP was found to be fully
relevant, representing an accurate reflection of CCRC’s infrastructure and the way in which it
is operated. The auditor concluded that CCRC’s DWQMP was accurate, current and relevant.
A number of opportunities for improvement (OFIs) were identified during the audit. These
OFIs have been included in the DWQMP Risk Improvement Plan and will help CCRC improve
efficiency, reliability or reduce the risk of future non-compliances.
8.1.2 Sewerage Operations
Performance against Customer Service Standards indicate good outcomes with low numbers
of sewer breakages/blockages, generally acceptable response times to sewerage incidents
and low numbers of odour complaints. The level of sewerage infiltration particularly for
Innisfail and Tully town is still higher than desirable.
Aging reticulation networks in Tully and Innisfail suffer extensive infiltration problems.
Significant capital funding is being directed to sewer relining programs, which should in part
address the infiltration problem. Peak wet weather flows into the treatment plants are still
high (probably due to the influence of surface infiltration) but after the heavy rains cease, the
86
sewage flows are reducing at a faster rate than previous suggesting the relining is having an
impact on ground water infiltration.
Significant capital expenditure has been committed to upgrade facilities at the Tully Sewerage
Treatment Plant. Design is completed for a new motor control centre (complete with new
switchboards). Construction will be delayed until mid 2021 to coincide with low sewage
inflows.
The financial position of sewerage operations is fair. Measures are in place to streamline some
operational expenses but significant factors such as depreciation for the treatment plants
(compounded by the small population base), will constrain any efforts to reduce sewerage
charges. The completion of major solar facilities at the treatment plants should offset some
of the cost increases from the network power supplier.
There were no breaches of Council’s environmental authority (licence) for it sewerage
treatment plants
In 2020/21 there were four (4) incidents reported to the Pollution Hotline for dry weather
sewerage spills in the year. 3 spill were in Lily Street as a result of failure of the 450mm
diameter ductile iron cement lined SPS3 rising main. Replacement of this asset was completed
in late 2021. One spill in Charles Street, which requires more investigation and condition
assessment of the asset to determine replacement/renewal strategies.
There was five significant wet weather overflows. Though wet weather spill are generally not
reportable to the Pollution Hotline but due to the severity of the incidences a record has been
kept. These overflows will be targeted for major upgrades in the sewer network in 221/22 to
reduce the probability of future over flow instances.

Tully Scheme
A significant number of water main assets in Tully were installed by local farmers. In the 1990’s many
of these donated assets were polyethylene or white pvc. These pipelines are generally inferior quality
(class) pipe, installed at relatively shallow depths and lacking proper bedding and backfill. In many
cases “as dug material” was put back over and around the pipe including large rocks and “sharp” stone.
Many of these mains are located near sugar cane farms, which during planting and harvesting time
rely on heavy machinery to carry out the majority of the work. Also, during this time, a large number
of cane trains run along these areas where they are in close proximity to some water mains, with the
resulting vibration also causing challenges. Ground movement from large changes in soil moisture
conditions are also another factor.
These rural mains are now accounting for a substantial proportion of emergency call outs. A number
of these rural mains have also been identified by Council as being uneconomic due to their failure
history, very long lengths of main, few connections and surprisingly low water consumption. Until
these mains are either replaced or decommissioned, the large numbers of breaks in these areas will
continue. Of the 92 main breaks recorded during 2020-2021, 2 of the rural mains accounted for 30 of
the call outs, these have had replacement works carried out during 2020 and 2021. Of the remaining
62 main breaks 43 are associated with rural mains. A number of the uneconomical mains are having
renewal work being undertaken in the absence of any formal policy to reduce the water service area
by decommissioning mains.
