Executive Summary

This assessment study aims to illustrate the severity of damage and destruction caused to the assets and infrastructure of the Cleaning Fund (CF) and the Public Corporation of Water and Sewage (PCWS) in Aden during the conflict period which started in 2015. In addition, the study provides the required interventions and the most urgent needs for both corporations.

Regarding the CF, most of the damage occurred to the vehicles and equipment. About 60% of the CF's equipment and assets were permanently destroyed, while the remainder 40% were left in very poor conditions. The transfer station and the dump sites require rehabilitation works and more vehicles to become able to restore their total abilities. Moreover, the maintenance workshops need rehabilitation works and lack many equipment, tools and spare parts. Besides that, buildings of the administrations in directorates need to be rehabilitated.

Therefore, the current priorities for CF are to supply new garbage containers, garbage collecting vehicles, dumpsite's vehicles (bulldozer and compactor) and mobile maintenance workshops. Furthermore, rehabilitation interventions for the buildings in directorates, maintenance workshops, transfer station and dumpsite are considered as high priorities for the CF.

In regard to the PCWS, old office buildings in the wellfields, headquarter, pumping stations and some other facilities of PCWS have been partially damaged. About forty well bores, three reservoirs, the central laboratory, the three disinfection units, and 2 main transmission pipelines in Bir Nasser wellfield have all been worn-out or partially destroyed. The sewage pumping stations were also damaged. Al-Arish, Kubota and Salah Al-Dain wastewater treatment plants with their office buildings and laboratories have been partially damaged. In addition, operation and maintenance equipment, tools, and vehicles, spare parts and occupational health and safety tools were damaged and looted.

Consequently, rehabilitating the wellfields and supplying suitable pumps to increase the wells' yield, conducting maintenance interventions for reservoirs, carrying out complete rehabilitation for sewage pumping stations, constructing new office buildings, renovating the wastewater treatment plants and supplying required O&M tools and equipment are the main priorities for the PCWS currently.

Besides the direct damages, the CF and PCWS faced indirect damages mostly through the electricity cuts, economic crisis, and rising prices leading to financial constraints.

Although some of the damaged facilities and infrastructure of both institutions have already been rehabilitated with support from the humanitarian organizations, such as UNOPS, Mercy Corps, UNICEF, Arab Fund, etc., there is still an urgent necessity for many interventions and projects to be done in order to aid these two local corporations to continue serving the local citizens in Aden city.

1. Introduction

The city of Aden is one of the most important and vital cities in the republic of Yemen. Located in the furthest southwestern part of the country, the city is considered as one of the most beautiful touristic attraction in the region. Previously, the city was widely known for its beauty, cleanliness and the high level of services in the development sector compared to the rest of the governorates in the country. The cleaning fund (CF) as well as the public corporation of water and sewage (PCWS) played a significant role in raising the urbane level the city has attained. Unfortunately, the crisis which started in 2011 along with the armed conflict the city witnessed in 2015 caused massive destruction and damage to a lot of the city's assets and infrastructure. Needless to say, the CF and the PCWS were among the most affected government agencies, which sustained severe damage and destruction in their assets and infrastructure.

The acts of destruction and damage to which these two agencies were subjected, contributed largely to the decline in the level of hygiene, cleanliness and water and sewer services in the city. Consequently, problems such as accumulation of waste around the city's streets and neighborhoods, severe shortage in water services in several areas, overflow of sanity sewer and the discharge of sewage into the see without any treatment started to emerge. All these problems caused many diseases and illnesses to breakout as well as pollution of the environment which left the city in a catastrophic condition.

In response to this catastrophe, several humanitarian organizations leapt to offer a helping hand in a rapid and urgent manner in order to save the city from this situation. Most of the aid provided focused on the field of wash, in which the CF and the PCWS received many aid projects. The efforts are still in progress regarding supporting these two agencies in order to enable them to substitute for the assets they lost and to rehabilitate their damaged infrastructure thus allowing these two agencies to regain the roles they played before the crisis. The following chapters in the study explain the current condition of the CF's and the PCWS's infrastructure and the projects needed in order to rehabilitate their infrastructure.

2. Methodology

This part demonstrates the followed procedures during the infrastructure assessment for solid waste fund, water supply and sewage institutions in Aden city. It aims to sum up the carried-out steps for gathering information, analyzing data and shortlisting the required interventions. It also contains some of the main observations and initial findings that were taken while collecting and analyzing information. Furthermore, it includes the remaining work tasks that will be taken to finalize the assessment study.

2.1. Gathering information

Preparing: as a first step, the assessment began with a desk research which included an overlook of the project's documents and existing reports and data concerning the infrastructure and assets capacities of CF and PCWS. By the end of the desk review, a work plan was designed illustrating the methodology that would be followed to implement the assessment. Along with designing the work plan, surveys and questionnaires targeting local communities, beneficiaries, senior managers and technical staff in CF and PCWS were formulated1.

Field Work: the field work started by preliminary meetings with administrations of CF and PCWS discussing the work plan and surveys prepared by the consultant, reviewing the current condition of both institutions, existing challenges and requirements and planning the timeline of consultant's field visits. By the end of these meetings, the consultant was given a long list drafts containing the requirements and needs of both institutions.

The preliminary meeting with the administration of the CF attended by

- CEO of the CF (Eng. Qa’ed Rashed Ana’am)

- Deputy GM of cleaning and hygiene affairs (Eng. Farooq Mohammed Zaid)

- Chief of studies and design department (Eng. Mohammed Handhal)

- Int’l and local organizations coordinator at the CF (Waleed Alhakimi)

1 Surveys and questionnaires are attached in Appendix (8)

Preliminary meeting with the administration of the PCWS, attended by

- GM of PCWS (Eng. Alawi Al-Mehdhar)

- Deputy GM of sanitation department (Eng. Zaki Al-Haddad)

- Consultant of GM for technical affairs (Eng. Kamel Alhamami)

- Chief of projects’ management (Eng. Hamdan Al-Hakami)

- Chief of coordination with the organizations (Eng. Angela Abdulrahman)

After conducting the preliminary meetings, the consultant with his team initiated the field visits and survey activities.

i. Cleaning Fund

For the sake of assessing the infrastructure of the CF, almost all administrations and facilities within CF were visited. The current situation and requirements of each administration/facility were considered during the field visits. A quick brief of the main observations taken during field visits can be illustrated as:

As a result of the conflict the country witnessed, Aden became the political capital of the country which resulted in the increase of population, consequently causing larger amounts of waste to be produced by the city of Aden to the point where the amounts of waste produced surpasses current capacity and capability of the CF.

Low earnings obtained by the CF currently has created a lot of financial difficulties and challenges, which prevented the CF from carrying out many of its activities.

A large number of the equipment and machines formerly owned by the CF were subjected to acts of robbery and destruction due to the conflict the city witnessed. Nearly 60% of the CF’s equipment and machines were damaged as a result of military operations during the conflict period.

- 9 -

The CF arranged for a makeshift transfer dump site in Al-Hiswa, Al-Mansoora to replace the transfer station in Al-Mansoora which stopped working because of infrastructure damage and loss of trailers which were used for transportation of waste to the dump site. Due to the shortage in equipment and machines at the temporary dump site, waste started to pile up and accumulate posing serious threats to the environment and general health. Moreover, the proximity of Al-Hiswa natural preserve to the temporary dump site, made things significantly worse.

Administration of afforestation and public parks’ incapability to oversee and monitor watering and irrigation of nurseries and parks caused trees in public parks and nurseries to die. In addition, the conflict in the city contributed to the destruction of a number of intersections, water fountains and corniches.

As a result of the theft and robbery to which the dump site was subjected, disposing of solid waste brought in from all directorates became very difficult.

The CF’s maintenance workshops were also robbed and lost many of the equipment and tools which were used to repair and maintain equipment and machines owned by the CF.

Exhaustion and fatigue to which a number of the CF’s machines and equipment were subjected and which the CF was incapable to repair because of its inability to provide spare parts.

ii.Water Supply System

The consultant with the help of his team visited the wellfields, main pumping stations, reservoirs, elevated tanks, workshops, central lab and disinfection units. Main observations taken during field visits are outlined as:

Number of bore wells stopped due to the malfunction of their pumps leading to reduce in the water production capacity.

The Water Central Laboratory and its equipment, including the chemical and bacteriological analysis devices, were damaged and looted.

All disinfection facilities were also destroyed causing a real threat from spreading water related diseases.

Due to illegal connections and leakages from worn out parts of the transmission and distribution, PCWS lost large amount of water and money.

The corporation’s inability to make up for the losses of operation and maintenance equipment.

- 10 -

iii. Sanitation System

The field visits covered main treatment plants, laboratories, main and sub pumping stations, main manholes and maintenance workshops. From the field visits and surveys the following were observed:

Clogging and eroding parts of the main and lateral sewer network (pipelines and manholes) leading to sewer overflows in some areas.

Some pumping station are out of service causing more burden on still operating stations.

Efficiency of WWTPs is under accepted limits, which means the sea is being contaminated by sewerage of Aden city.

Severe damage sustained by the corporation’s laboratories.

Immense losses in operation and maintenance equipment which rendered the corporation unable to carry out its tasks.

Finalizing: all collected information during meetings, interviews, field visits, and survey activities were classified and rearranged to be ready for analysing.

2.2. Analysing

Initial Findings: by analyzing the observations and gathered information during field visits, interviews and survey activities. The following main initial findings were concluded:

Necessity of providing the minimum number of containers and vehicles which commensurate with the amount of solid waste generated in Aden city to prevent wastes pilling up causing the spread of diseases.

Rehabilitation of Al-Mansoora transfer station should be considered as a high priority intervention, since rehabilitation of the station will lead to a number of positive results.

While the CF is suffering from financial difficulties, rehabilitation of the recycling hangar in the dumpsite can assist the CF in generating revenue which can be used in funding other activities.

The amount of water production from wellfields (well yield) can be increased by replacing the malfunctioning pumps in the wells.

Rehabilitation of the water supply network will reduce the loss caused by leakages in the dilapidated network.

- 11 -

Rehabilitation of the disinfection units and the central lab should be considered as a high priority project due to the impact of this project on reducing the infection of water related diseases.

Importance of rehabilitating the worn-out sewer network especially in the areas facing frequent sewer overflows, giving that sewer overflow is one of the main reasons of spreading waste water related diseases.

Supplying the PCWS with the appropriate tools and equipment for unclogging manholes should be considered as a priority.

Rehabilitation of the pumping stations will reduce the overflows of sanitation network in Aden city.

Rehabilitation of the WWTPs should be given a high priority since currently the sewerage is conveyed directly to the sea causing a contamination problem.

Classifying: second step was classifying the requirements and needs of CF and PCWS into sub-projects. The CF's required interventions were sorted into 9 modules (Cleaning Fund Headquarter, Cleaning Fund Administrations in Directorates, Transfer Stations, Dumpsite, Maintenance Workshops, Afforestation and Parks Administration, Sand and Construction Waste Management, Capacity Building and Environmental Awareness Center). Whereas water supply system required interventions that were sorted into 7 modules (Wellfields, Reservoirs and Tanks, Water Network, Pump Stations, Central Laboratory, Disinfection Units and O&M Materials). However, the sanitation system necessary requirements were classified into 6 modules (Wastewater Network, Manholes, Pump Stations, WWTP, O&M Materials and Maintenance Workshops). Then, each module was classified into sub-projects based on the requirements for each module.

Shortlisting: sub-projects were rated as urgent, medium priority, low priority. Along with considering the initial findings mentioned above, the main criteria considered while rating sub-projects were as follows:

Impact of sub-project on reducing solid waste related diseases.

No. of beneficiaries.

Necessity of sub-project to local community.

Impact of sub-project on rising and improving the overall performance of CF & PCWS.

Expected Sustainability of the sub-project.

Impact of sub-project on reducing the expenditures of CF & PCWS

Impact of sub-project on the social and economic situation and peace building efforts.

- 12 -

Before submitting the shortlist to PWP and UNDP, a second meeting with administrations of CFs and PCWS was conducted to discuss and approve the shortlist (urgent) sub-projects.

The shortlist should be approved by PWP and UNDP taking into account the budget limits and available funds.

2.3. Approved projects

Project concepts will be conducted for the sub-projects that will be approved by stakeholders and UNDP. Project concepts will include the following for each approved intervention:

- Project title

- Project location

- Project rational

- Estimated budget (BoQ)

- Implementation duration

- Expected impact of intervention, potential risks, and beneficiaries

3. Cleaning Fund

3.1. Introduction

Since the establishment of the Cleaning Fund in 1999 under cleanliness law number 20, the CF has carried out many environmental and health-oriented activities and practices that presented the city in a light fitting with its political, economic and historical status. According to the cleanliness law, the CF is considered to be financially and directorially independent, where activities and practices carried out by the CF are financed by fees mandated by the CF. These fees are explained as follows: - Cleaning fees obtained from stores and other facilities. - Development fees obtained as a rate for services offered by the CF. - Revenues made from advertisement billboards spread around the city. - Specified amounts from the national budget. - Donations and offers from international and local associates.

By the same law, the following responsibilities are placed upon the CF:

- Daily collection of residential trash and waste from streets and neighborhoods around the city followed by transportation of waste to a lawful place (normally outside the city).

- Final disposal of waste in a proper way so as to prevent pollution and damage to the environment of the city.

- Emphasis on the importance of carrying out cleaning services by adopting modern ways and technologies that aim to preserve health and safety of the city and prevent environmental pollution.

- Afforestation and tree-planting activities on the side of roads and on median strips and organizational irrigation of these plants in order to preserve their greenness.

- Periodic maintenance for locations heavily populated with trees and plants through trimming of trees, painting and cleaning of tree basins and application (Spraying) of pesticides on trees and plants in order to get rid of harmful insects.

- Construction of aesthetic sites and architectural structures that are representative of the city and its history.

- Rehabilitation and maintenance of historical statues and sites and prevention of their removal. - Studies and designs for future development and betterment projects. - Following up and obtaining of fees and revenues as described in the cleanliness law and ensuring

procurement of these income resources as to become able to finance activities and works carried out by the CF.

3.2. Organizational Structure of the CF

The CF is divided into a number of administrations such that each administration is assigned with certain responsibilities as shown in the structure below

The CF is run by a board of directors and is considered as the highest authority for the CF. It is led by the governor of the governorate in which the CF is located and has full authority to observe, direct, make up policies and decide on programs and plans corresponding with the purposes for which the CF was founded.

The CF is headed by a Chief Executive Officer (CEO) whose responsibilities include management and leadership of operations carried out by all administrations and departments at the CF. There are three deputies for the CEO and are assigned based on duties and responsibilities as follows:

Deputy Director of Administrative and Financial Affairs: responsible for management of financial and administrative affairs and aspects of the CF.

Deputy General Manager of Hygiene Affairs: responsible for following up on daily cleaning activities, performance levels, amounts of transported waste to the dump site – located in Bair Na'ama, Al-Boraiqa. Additionally, is supervisor of Heads of Hygiene Departments in the directorates.

Deputy General Manager of Technical Affairs: responsible for all technical activities and follow-up of maintenance workshops and supervision of daily monitoring activities of the condition of the cleaning processes in the city and reporting technical needs and necessities that would ensure continuous technical maintenance of machines and equipment.

3.3. Current Situation and Required Intervention:

Ever since the establishment in 1999, the Cleaning Fund has invested massive efforts in improving cleanliness levels and standards in the city, a mission accomplished by overcoming struggles and challenges the CF faced, resulting in a number of consecutive achievements. In addition, during the period from 1999 to 2010, the CF succeeded in gaining a fleet of vehicles and equipment enabled it to perform cleaning activities effectively and professionally.

In 2009, Ade city won first place in the environmental contest held by the Environmental Protection Agency, which included aspects of cleanliness and afforestation. However, since the beginning of the political crisis in 2011, which affected the progress of the CF negatively, evident through receding levels of cleanliness. Moreover, and due to robbery and vandalism of CF-owned assets and equipment, the CF was rendered incapable of removing waste off streets and neighborhoods around the city, causing waste to pile in large amounts and for long periods of time which resulted in the spread of dangerous diseases and having citizens resort to burning these wastes in order to get rid of them.

- 16 -

The situation in Aden continued to deteriorate reaching its worst during the armed conflict which took place in 2015, which added additional burdens and difficulties causing the CF's infrastructure to worsen significantly. About 60% of the CF's assets and equipment were permanently lost, while the remainder 40% were left in very poor conditions to the point where previous cleaning and waste-collecting activities have dropped massively causing waste and sand to pile up around the city in an undesirable manner. These piled up wastes which increased quickly started to pose serious danger to the health of citizens and environment alike. Luckily enough, the CF in cooperation with influential local and international organizations formed rapid interventions which contributed to alleviation of the threats caused by these diseases and reducing the magnitude of catastrophes that would have otherwise ensued such as the cholera outbreak. In addition, the CF's income was seriously affected due to these conflicts, where services normally carried out by the CF have largely dropped because of its incapability to manage between its limited operating costs and hygiene related duties. With that said, the CF was faced with many difficulties and challenges surmised in the following points:

1- Incapability of CF's machines and equipment to remove waste accumulated in large amounts estimated at (750 tons/day) and which is expected to grow because of the increase in the population the city witnessed as a result of displacements of large numbers of people because of the conflict as well as the raise in the number of diplomatic delegations accompanied with the reassignment of Aden as the country's capital city. All these factors made it very challenging to remove waste off the streets causing the problem of accumulated waste to grow largely especially given the CF's loss of more than 60% of its assets and equipment because of the conflict. With that said, it has become rather urgent that the CF

- 17 -

receives the necessary funds and support it can use to obtain new equipment instead of the current renting policy it carries which is very costly.

2- Significant increase in the amounts of construction waste around the city's streets and neighbourhoods which is roughly estimated to be about (2,470,000 cubic meters) according to the latest statistics carried out by the CF's administration of sand and construction waste.

3- The CF's inability to afford large daily rental costs of machines and equipment. 4- Shortage in the CF's financial resources which renders it unable to afford costs of operations carried

out in high levels. 5- The CF's inability to steadily secure cleaning workers' salaries, which are estimated to be around (3900

employees) due to lack in financial resources.

However, and in light of all these difficulties and challenging times, the CF, and to its best ability manages to perform periodic cleaning campaigns aimed at cleaning the streets and neighborhoods of the country's temporary capital, Aden.

Unfortunately, these cleaning campaigns are temporary solutions that come at very great costs. Therefore, permanent and constant solutions to the cleaning and hygiene issue in Aden need to be made. These solutions are best simplified in the providing and supplementation of machines and equipment that can cover the amounts of waste produced by the city of Aden.

Following is a detailed study of the current condition of the CF's infrastructure and needs that must be provided for the CF to be able to carry out its duties to the required levels of efficiency.

- 18 -

3.4. Main Headquarter

The CF's headquarters main building is located in Khormaksar directorate. It is a one-storey building located on one of the lands owned by the CF and it holds many of the administrative offices as well as the hall used for conferences and meetings. In addition, CF is planning to use this hall as a training centre. Although the building is in an excellent condition where no rehabilitation works are required, there is a space problem in regard to administrative offices that is serious enough to the point where multiple administrations are located within one office. Therefore, there is a need for building an additional floor which should allow for more office space that could solve the current problem.

- 19 -

Additionally, a number of these administrations are in need for certain office-related equipment and necessities, which are shown in the table below.

3.5. Training and Environment Awareness Centers.

Despite specifying a hall as training center, the center does not own enough equipment or tools which enable training sessions to be carried out. In addition, CF has an environment awareness center, which requires the suitable equipment to conduct awareness campaigns effectively.

For both centers to be able to carry out their duties, the following equipment and tools are required.

3.6. Cleaning Administrations in the Directorates

Because of the recent urban sprawl the city of Aden witnessed, where growth in many urban areas as well as the inhabitation of previously uninhabited regions progressed rapidly, the CF was left with new burdens with which it is not entirely able of tackling. Moreover, the period of time whereupon the country suffered from the political conflict caused the population in Aden to grow leading to an increase in the amounts of waste produced by the city which require significant resources in order to have it removed off the city's streets and neighborhoods. However, given the limited resources of the CF's which became more prominent since more services have become required due to this increase in the amounts of waste, the burdens on the CF's administration grew exponentially. Therefore, the CF resorted to dividing highly populated directorates onto less populated areas that would be capable of containing this expansion in population and waste alike, thus minimizing and allowing for distributing of large amounts of work among these areas, which include ( Al-Boraiqa – Inma' and Al-Sha'b) and (Al-Mansoora – Abdulaziz and Al-Qahera) which brought the number of cleaning administrations in the directorates up to ten administration, where each one of these administrations is in charge and owns its own separate equipment, machines and workforce. The 10 administrations are listed as follows:

Al-Mansoora (Al-Qahera) 6. Al-Tawahi 1. Sheikh Othman 7. Al-Mu'alla 2. Dar Sa'd 8. Crater 3. Al-Boraiqa (Al-Sha'b) 9. Khormaksar 4. Al-Boraiqa (Inma') 10. Al-Mansoora (Abdulaziz) 5.

- 22 -

These administration branches are included within the general administration of cleaning affairs, each of which is responsible for following up and carrying out cleaning activities (mainly collecting waste and cleaning of streets) in its own region as well as monitoring performance levels of workers and documenting amounts of waste transported to the dump site in Bair Na'ama on a daily basis. In order to run smooth operations, these administration branches were constructed based on the editorial structure shown in the following figure.

3.6.1. Buildings and Facilities

Each administration owns its building which is used for management of cleaning activities and practices, organizing and storing of editorial documents, reports and statistics as well as storing of equipment and machines with the exception of Al-Mansoora – Al-Qahera and Al-Boraiqa – Inma' as these two administrations do not yet own their administrative buildings.

The data collected during the field visits to these administrations show how severe the damage sustained by these buildings is, which was primarily caused by acts of robbery and vandalism. Additionally, some of these buildings were totally damaged as a result of the military operations that happened inside the city. Projects concepts comprises more details and a number of pictures that illustrate the severity of the damage sustained by the administrative buildings in the different directorates.

Given the importance of the cleaning administrations in the directorates is, the CF is hoping of sponsors and humanitarian organizations to foster rehabilitation and renovation works of partially destroyed facilities and the construction of new buildings in areas where totally destroyed buildings and areas that do not own their administrative buildings.

3.6.2. Vehicles and Equipment

For the cleaning administrations in the directorates to be able to perform their duties efficiently, the CF provides the necessary equipment and tools for each directorate based on population density and amounts of waste produced by each of these directorates. Therefore, each administration has its own specified share of equipment and machines separately from the other administrations.

A. Containers Normally are metal or plastic boxes of various capacities (1 m which are the most common type, 1.1 m and 3 m). Cleaning and hygiene administrations in the directorates distributed these containers around Aden’s streets and neighborhoods, and they are used specifically for collecting waste and trash bags in order to have waste and trash collected and transported using specific machines and vehicles in a periodic fashion. The containers are considered among the most damaged equipment in a constant manner, caused mainly by increase in humidity in the city, which causes corrosion of metal containers rather quickly. Additionally, burning waste inside containers which results in damage of plastic containers. Despite the support and sponsorship, the CF received from humanitarian organizations, such as Emirate Crescent, UNICEF, UNOPS, Ark Assistant and others, which mostly included supplying containers of different capacities, thus improving the practices and activities of the CF, yet administrations of the CF still need large numbers of waste containers. As a result of this shortage in containers, citizens in several areas started to throw waste and trash on the streets and around the neighborhoods of the city leading to real and serious health and environmental issues. The number of containers currently used in Aden is estimated to be around 800 containers of 1 cubic meter in addition to 50 containers of 3 cubic meters, most of which obtained through support the CF received from humanitarian organizations. However, estimations put the number of needed containers at (1600 – 2000) of 3 cubic meters in capacity in order to cover the demand mandated by the amounts of waste produced by the city.

B. Vehicles Each of the administrations in the directorates uses its own waste collecting equipment in order to collect waste from the different neighborhoods and streets in the city after which have it transported to one of the transfer station in Al-Mansoora directorate or to the dump site in Bair Na’ama in Al-Boraiqa directorate. Two types of these machines are used for this purpose, either ordinary waste collecting vehicles or waste collecting vehicles equipped with compactors.

However, due to acts of robbery and theft that started in the last months of 2011 reaching the conflict period which started in March of 2015, the administration of the CF lost more than 60% of its equipment, which the CF could not recover while the remainder 40% are severely damaged due to overuse of these equipment in order to make up for the loss in equipment.

Damaged Plastic Containers

The following table illustrates current condition of the remaining vehicles at the CF, used by administrations of the CF

For administrations of the CF to become able to carry out its practices and activities in the desirable manner without much difficulties and obstacles, the loss of equipment must be substituted in proportion with the amounts of waste produced by Aden’s various directorates. The CF’s urgent needs of vehicles are listed as follows:

3.6.4. Field Workforce:

The CF strived to provide a workforce capable of fulfilling it capacities in order to improve the hygiene’s level in the directorates regarding sweeping works, waste collecting, afforestation and maintenance workers (engineers and technicians), the table below shows how the workforce is distributed among the city’s directorates

As shown in the tables above, numbers of field, editorial and technical workers vary among directorates, caused by the nature of each directorate in terms of area, location, population and nature of dominant activity (economical/residential). The CF considered the previous factors upon assignment of workforce and number of machines and tools in accordance with the previously mentioned factors.

3.7. Al-Mansoora Transfer Station

Given how far away and remote the Bair Na'ama's dump site – where the final stage of solid waste disposal occurs – is located, the process of transporting the collected waste from all areas in Aden to the dump site location is rather inefficient and causes fatigue to waste collecting machines, longer journeys and leads to significantly higher consumption of fuel. With the purpose of making the disposal of solid waste more efficient, the CF established a transfer station in Al-Mansoora directorate. Located next to Express Petrol Station, the transfer station is one of the most important assets owned by the CF. The station is designed to receive solid waste brought in by collecting and compacting machines from all directorates in Aden, this waste is unloaded into large truck trailers (load 40 tons). Upon reaching the specified load of these truck trailers, solid waste is transported to the dump site Bair Na'ama in Al-Boraiqa directorate.

Al-Mansoora's transfer station is one of the assets owned by the CF which was severely affected during the conflict the city of Aden witnessed. The station lost most of its equipment which prevented the formerly normal activity of receiving and transporting solid waste produced by Aden city, estimated at about (750 tons/day). Because it became nearly impossible to work within the capacity expected from the station, a temporary dump site was set up (Al-Hiswa Dump Site) in Al-Mansoora directorate. Additionally, necessary equipment and machines were rented and paid for on a daily basis, which has strained the CF's very limited budget.

The station is made up of a number of machines and facilities designed to serve the purpose for which the station was established. Following, is a detailed explanation of the main components of the station

3.7.1. Equipment and Tools

i. Truck Heads and Trailers Since the establishment of the station in 2014, it was in possession of the necessary equipment suitable for the station's type of work. The equipment the station owned were four truck heads and six trailers (load 40 tons) used for periodic transportation of waste from Aden's different parts to the station and later on to the dump site in Bair Na'ama. Only two of the four trailer heads are left and of these two, one is in a poor condition. Five of the truck containers were damaged beyond repair, which leaves a single functioning trailer. Currently, the station is stopped and unable to conduct the role for which it was established.

- 33 -

ii. The Transfer Station Scale

The station owns a truck scale (capacity 40 tons) for weighing waste collecting vehicles coming from Aden's directorates. The weighing process is carried out in order to confirm whether the allowable load has been reached as well as account for the amount of waste collected daily and having it compared against the number of functioning equipment and the amount of gas and oil necessary for operating this equipment. Even though the scale is in a good and working condition, it requires constant and periodic maintenance. Additionally, the scale is connected to a computer that monitors and documents the trips in order to construct periodic reports on the total number of trips carried out classified based on equipment and region.

- 34 -

3.7.2. Structural Facilities

i. The Dumping Hill The dumping hill is used for allowing the waste collecting vehicles to unload the waste through a metal funnel – located at the top of the hill – into the trailers which are located below the funnel. The hill simplifies the process of unloading garbage collecting vehicles significantly, which is why it is very important to carryout rehabilitation and maintenance works on the rail alongside the hill (shown in the picture). In addition, the metal funnel, which has started to corrode as a result of rust needs to be replaced. Also, the upper part of the funnel, through which garbage passes, should operate as a closed system in order to prevent garbage from flying around causing pollution to the surrounding area of the station.

- 35 -

ii. Fuel Station: Given the importance of the station's location, as it is a connecting point where vehicles collecting waste as well as waste transporting vehicles passes through, a fuel station was provided for the station in order to supply vehicles with the necessary amounts of fuel to operate according to their designated roles. Fortunately, the fuel station was left unharmed and is in a good working condition.

iii. Surrounding Fence of the Transfer Station The northern part of the fence surrounding the station was damaged, raising security-related concerns in regards to having the transfer station and its assets secured and safe, which dictates the need for rehabilitation works on the damaged parts of the transfer station.

The table below shows the remainder of damaged machines and equipment, some of which were temporarily and urgently rehabilitated in order to perform a few crucial tasks at the station.

3.8. Al-Hiswa Temporary Dump Site

Due to the sever lack of equipment and machinery at Al-Mansoora's transfer station which has rendered the station incapable of receiving and transporting all the waste produced from all areas in Aden to the dump site in Bair Na'ama and because the dump site in Bair Na'ama was forced to shut down after four in the afternoon due to security concerns given the closeness of the dump site from the coalition's forces camp, the CF resorted to contrive a temporary transfer dump site in Al-Hiswa area in Al-Mansoora directorate. The aim of this temporary transfer dump site was to receive the waste brought by the CF's equipment during the afternoon period – at which time the dump site in Bair Na'ama was closed – and then have the waste transported during the morning of the following day to the dump site in Bair Na'ama, using the CF's available equipment as well as the equipment rented from private parties, in order to prevent the accumulation of waste at the temporary dump site.

The CF was able to manufacture a sufficient setup for the temporary dump site through surrounding the location with sand and large trees in order to preserve a healthy and environmentally friendly setting within the surrounding area and to protect the area from flying sand and plastic bags. Despite the precaution measures the CF took, the location of the temporary dump site is rather unsuitable considering that it’s located within the Hiswa natural reserve. The negative effect the temporary dump site has on the Hiswa natural reserve is too significant, which commands a need to have both Al-Mansoora's transfer station and the dump site in Bair Na'ama

reactivated full time and completely shut down the temporary dump site in order to protect the Hiswa natural reserve healthy, clean and free of any pollutants that could cause serious harm.

What makes the situation at Al-Hiswa temporary dump site worse is the lack of any treatment procedures that could dispose of the accumulated waste which the CF cannot – with its current

- 38 -

resource – transport to the dump site in Bir Na'ama, leading to increase in the amounts of accumulated waste day in day out causing a major environmental catastrophe in the area.

3.9. The Dump Site

The dump site, located in Bair Na'ama in Al-Boraiqa directorate behind Bazar'a Steel Factory is an asset owned by the Cleaning Fund where the final stage of solid waste disposal occurs. The location of the dump site was carefully chosen as to be far-removed from residential areas and ground water sources; where the nearest ground water well is about 60Km away whereas the nearest residential compound is located at a distance of 1.5Km from the dump site. This suitably distant location of the dump site prevented any negative effects from harming citizens and water sources.

The area of the dump site is estimated to be around 4Km2, which requires a security fence in order to protect the dump and the equipment and machines from robbery and damage to which the dump site was exposed during the recent conflict.

In 2010 the dump site used to receive about 450 tons/day of solid waste; however, this number has risen and reached what is roughly estimated to be 650 tons/day of solid waste delivered from Aden's eight directorates. This increase in the amount of solid waste is due to the large increase in the population in the city of Aden caused by declaring Aden as the capital of the country as well as the increase in the number of refugees from neighboring governorates where conflicts are still ongoing.

Solid waste in the dump used to be disposed of by burial, a modern method that complies with the international environment standards 3-5-meter-deep layered holes that are covered with sand and after which they are compacted using proper equipment, such as bulldozers, compactors and wheel loaders. Unfortunately, all these machines and equipment were either robbed or damaged during the conflict.

- 40 -

Currently, the collected waste is spread over large areas within the dump site and is left to be exposed under the sun rays in order to get rid of the leachate; where strong sun rays dry off a big part of the leachate and the remainder is absorbed by the sandy soil of the dump site. After that, solids are compacted until 50-60% of the initial size has shrunk, which is accomplished using a wheel loader and a newly obtained bulldozer from UNOPS. Even with the aid of this new equipment, the work load is still too great to be fully covered, especially since the formerly used wheel loaders and bulldozers are now in Dar Sa'd's central maintenance workshop as they are in a bad shape and require full maintenance. Previously, waste used to be covered after compacted with a layer of sand, which used to be transported from a site 300 meters away from the dump site using dump trucks, that are currently non-functional, causing waste to be left uncovered and exposed leading to unfinished disposal of solid waste, which renders the dump site a source of air pollution.

Additionally, the proximity of the dump site to the coalition's military campground, and due to security concerns, the dump site is forced to shut down all its operations after four o'clock in the afternoon, which is one of the problems that caused the CF to resort to using Al-Hiswa temporary transfer dump site despite its negative effects on the environment.

The dump site consists of a number of machines and facilities designed to serve the purpose for which it was established.

Following, is a detailed explanation of the main components of the dump site:

3.9.1. Bulldozers and Wheel Loaders

In the past, the dump site owned two bulldozers that were used for compacting solid waste and three wheel-loaders and two dump trucks used for loading and transporting waste and sand into the dump site. However, due to the theft and damage to which the dump was exposed, one of the bulldozers is currently out of service (found at Dar Sa'd's maintenance workshop) and the other one while is in a working condition, it requires extensive maintenance. As for the wheel loaders, they are all at Dar Sa'd's maintenance workshop as they require extensive maintenance. One of the dump trucks is at Dar Sa'd's maintenance workshop as it requires extensive maintenance, while the other one is still in a working condition. Given the state of the dump's equipment, the UNPOS has provided the dump with urgent and new equipment: bulldozer, wheel-loader and wheel-tractor scraper.

- 41 -

Nevertheless, compared with workload the dump site receives (750tons/day), the number of equipment is still insufficient, which commands supplying the dump site with the necessary equipment for it to fully carry out its duties.

3.9.2. Scale

The dump site owns a German made scale (capacity 80 tons), which has been out of service since 2015 and is need of maintenance works to operate again. Also, the dump owns a Chinese made scale (100 tons) that was provided by the UNOPS. In order to smooth the dump's work, the CF's management found it crucial to rehabilitate the old scale.

- 42 -

3.9.3. Structural Facilities

i. Administrative Buildings: There is one administrative building equipped with facilities, such as bathrooms and security rooms that are in a poor shape and require rehabilitation, renovation and lightening works.

ii. Recycling Hangar: The dump site used to own a recycling hanger where waste made out of paper used

to be recycled by a private investor. However, the recycling hanger was put out of work due to the conflict in the city. The CF is working to rehabilitate the recycling hanger in order to put it back in service to recycle glass, plastic and paper waste. Additionally, it is expected that the rehabilitation of the recycling hanger could bring investments in the waste recycling field and the revenues could benefit the CF's greatly given its dire need for means through which rehabilitation works can be accomplished.

iii. The Fence: Building a fence surrounding the dump site is a crucial need in order to protect the site and the equipment it owns from any robbery or destruction. It also will allow monitoring of incoming and outgoing waste, management of waste that is being recycled and/or disposed of in an effective way.

- 43 -

The table below summarizes the current condition of the dump site and all its parts.

In order to have the dump site regain its ability to compact and bury the waste it receives daily to completely dispose of solid waste; it requires to be provided with the machines and equipment it lost and to have its damaged pieces repaired. These needs can be summarized in the table below.

3.10. Administration of Afforestation and Public Parks

The CF has a special administration which falls under the technical administration and which is called Administration of afforestation and public parks. Through this administration, the CF aims to increase green lands in the city of Aden, a goal to be achieved through monitoring parks and following up on tree planting activities in parks, corniches, streets and neighborhoods of the city of Aden. In order to achieve such purpose, the CF established nurseries. The CF also specified a crew consisting of workers, machines and drew up strategies that would enable administration of afforestation and public parks to carry its duties to the highest standards.

However, with the beginning of the military operations in the city, which led to the loss of several afforestation machines and equipment as well as exposing parks, water fountains and nurseries to acts of vandalism and robbery because of the administration’s incapability of monitoring and watering these plants throughout the conflict’s duration which the city witnessed. Consequently, administration of parks and afforestation is currently struggling with extreme difficulties which prevents the administration from carrying out activities in a steady manner.

- 45 -

Despite the dire situation with which the administration struggles and the severe shortage in resources, it still managed to reconstruct several parks and corniches and plant trees in several intersections and median strips The estimated area of public parks monitored by the administration of parks and afforestation is nearly 604800 square meters, total area of afforestation sites in median strips is 315900 square meters, for afforestation sites in intersections is 21682 square meters. The total estimated area of tree planting activities in corniches is around 46000 square meters. The table below shows the current infrastructure of administration of afforestation and public parks:

There are still many tasks which the administration of afforestation and parks must accomplish and monitor. For this administration to be able to improve its afforestation activities and rehabilitation of tree-planting locations in the city, it is necessary to take into account the supplementation of tree-planting tools, equipment and strategies as well as these related to the rehabilitation and watering of nurseries in order to restore the green cover which contributes to improving the city's humid and rather hot weather.

3.11. Administration of Sand and Construction Waste

The administration of sand and construction waste at the CF is one of the most effective administration whose main mission is removing sand waste caused by construction activities which pose difficulties for cleaning workers. During the military operations the city witnessed, a large number of the administration's equipment was damaged and stolen such as large vehicles and wheel loaders which were used in the fights that happened in the city. The remainder of the equipment was in a very bad condition that won't suffice for the kind of work the administration carries out. The table below shows the condition of the equipment and machines currently owned by the administration of sand waste:

Given the fact that the CF owns machines and equipment of various sizes and shapes that are prone to constantly break down and malfunction which mandates a need to perform maintenance works on these machines in order to have them available whenever needed, the CF established three maintenance workshops upon which befalls the task of performing periodic maintenance works on machines and equipment owned by the CF. Exemplary works of these workshops include oil, filters, tires and batteries changing, repair of any out of service machines or equipment owned by the CF. The work amongst these three workshops was assigned as follows:

i. Central Maintenance Workshop in Khormaksar: Responsible for maintenance and repair works for CF-owned machines and equipment operating within the first main area: Khormaksar, Al-Tawahi, Al-Mu'alla and Crater.

ii. Central Maintenance Workshop in Al-Mansoora: Responsible for maintenance and repair works for CF-owned machines and equipment operating within the second main area: Al-Mansoora, Al-Sheikh Othman, Dar Sa'd and Al-Boraiqa.

- 49 -

iii. Productive Maintenance Workshop in Dar Sa'd: Responsible for maintenance and repair works on heavy and large machinery and equipment.

Despite the CF's great efforts in providing all necessary needs for the maintenance workshops, the financial challenges with which the CF struggles, especially low income, have caused the CF to become unable to perform rehabilitations works, such as renovation of buildings, supplying necessary tools, equipment and spare parts used in maintenance works on broken down machines, on these workshops.

The three maintenance workshops were severely affected during the recent conflict in the city. Acts such as robbery and vandalism reached all three workshops. Below, is a detailed explanation of the current condition of the workshops:

3.12.1. Buildings and Infrastructure

Despite everything that has happened to the maintenance workshops, possible maintenance works are being carried out using available tools. However, main buildings of the workshops were partially damaged, bathrooms require urgent maintenance, and the workshops also require installing proper lightening.


- 50 -

3.12.2. Tools and Equipment

Because the CF's budget has become very limited which has caused the inability to provide maintenance workshops with the necessary tools and equipment, as the majority was lost due to the conflict. Because of the importance of the work carried out by these workshops, the following tools and equipment are very necessary for the workshops to perform their duties:

o Maintenance tools and equipment of various machines (Technicians Maintenance Kits)

o Electricity generators to ensure continuous work during power blackouts.

o Tools and equipment for welding machines.

o Car washing tools to ensure these vehicle's safety and waste-free status.

o Mobile maintenance workshops equipped with all field maintenance and welding tools.

Periodic Maintenance Requirements (Annual Needs of Maintenance Workshops)

The CF requires yearly supply of necessities for machines and equipment, such as oils, tires, filters, etc. The table below shows these requirements.

3.12.3. Spare Parts

The loss of about 60% of the CF's machines and equipment has caused more stress to be directed towards available machines in aims of substituting for the shortage in the number of machines and equipment, which has caused fatigue to a number of these machines and being out of service. Currently distributed among the three workshops, these machines urgently require spare parts to be provided. The table below shows the number of machines existing currently at the three workshops and the requirements of each of these machines.

3.14. Recommendations

i. The rehabilitation of Al-Mansoora transfer station must be viewed as a highly urgent intervention, which upon completion, the expected positive outcome can be summarized as follows:

Increase the number of transportation trips. Due to the current condition of the station where it is unable to receive waste from all directorates, the CF resorted to transport waste using waste collecting vehicles to the dump site in Bair Na'ama which is 35 Km away from some of the directorates, which takes around 2 hours to make the trip back and forth to the dump site. Therefore, vehicles are not able to make more than three trips every day. However, in case the station was rehabilitated, the number of trips for each vehicle is expected to reach 6-9 trips daily.

Quick performance and transportation of more amounts of waste. With the increase in the number of trips for each vehicle, the amount of waste transported will definitely increase which helps with the problem of lack of equipment with which the CF struggles.

Shutdown of Al-Hiswa temporary station Upon rehabilitation of Al-Mansoora transfer station, Al-Hiswa temporary station will no longer be needed, which has become a site where large amounts of waste accumulate causing health threats for the region especially Al-Hiswa natural reserve.

ii. In 2016, the CF was given around 1500 plastic containers from Emirates Red Crescent. However, due to misuse of these containers especially when the citizens burned the waste inside these plastic containers leading to damaging a large number of these containers. The pictures below show a number of the damaged plastic containers.

Therefore, it is recommended that instead of providing plastic containers, metal containers should be considered as they are less likely to get damaged.

iii. Due to the financial challenges with which the CF struggles, it is recommended that humanitarian organizations and other sponsoring partners foster and support projects that would enable the CF from earning a financial revenue which it can use to manage and run more of its activities. With that said, it was found more effective if the recycling unit at the Bair Na'ama dump site is to be activated and rehabilitated, from which the CF could benefit by either recycling waste directly or renting the recycling unit to a private investor, which was the case in the past.

4. Public Corporation of Water and Sewage

The public corporation of Water and Sewage was established under republic decision number 267 in 2000 as a government agency responsible for water and sewer services. Since its establishment, the corporation aims to provide water and sewer services in a way that protects the public's health and the environment and which is satisfactory for the beneficiaries. Similar to the CF, the PCWS is financially and editorially independent, where it mainly depends on revenue and income earned through collecting on water and sewer services bills to provide its operation costs and finance development projects. The corporation is headed by a board of directors made up of 8 members as follows:

1. Aden Governor 2. General Director 3. Director of Water Resources (Aden-Lahj-Abin) 4. General Director of Planning and International Cooperation 5. Director of Finance Office Aden 6. Citizen Representative 7. Private Sector Representative 8. Director of the Board Secretariat

The board of director is seconded by the general manager who is responsible for all editorial and financial departments and administrations within the corporation. Headed by the general managers are two deputies one is Deputy GM for Water Affairs who is responsible for management of operation activities, overseeing and treatment of malfunctions in the water department in the city and monitoring administrations of wellfields control and maintenance of electro-water equipment and workshops. Whereas the other deputy is Deputy GM for Sewer Affairs who is responsible for management of operation activities of the sewer department in city of Aden as well as management of treatment plants and laboratories.

Since the establishment in 2000, the corporation was able to provide water and sewer services in a manner that preserved the cleanliness of the environment and satisfied the citizens. During this period, the corporation carried out several projects through which it was able to improve and better its services as well as deliver these services to most of the areas in Aden city. The water services reached about 86% of the population whereas sewer services reached 69%. The corporation continued to provide constantly good level of services until 2011 when the political crises began and adversely affected the PCWS. Matters only grew worse in 2015 when the armed conflict started. Due to these crises and conflicts, the corporation was severely affected and lost a lot of the income resources upon which it depended to finance its activities. Additionally, the corporation lost many of its assets and things continued to worsen to the point where the corporation became unable to perform necessary maintenance works to maintain and keep the equipment and machines that got worn-out and went out of service.

Within this destruction and damage of the corporation's assets and equipment, the population in Aden witnessed a huge increase, resulting from declaring Aden as a temporary capital of the country, which caused to overload assets of the corporation which were still in service. Facing all these challenges, the corporation was rendered incapable of providing the citizens with clean water and sanity sewer overflow became a recurrent problem, which caused Aden city to suffer from several serious problems that endanger the safety of the people and the environment alike.

In order to save the city from the catastrophic condition it reached, several humanitarian organizations offered significant help. However, despite the support and help the corporation received, the repair and replacement of all that was damaged in the crisis of 2011 and the conflict of 2015 still requires extensive efforts that would enable the corporation to resume its ability to carry out its operation activities and projects.

4.1. Headquarters

The headquarters of Water and Sewage is located in Crater directorate. It is made up of a building of two floors and includes many administrative offices. PCWS needs to expand the headquarter building to add new offices.

Although the existing building is rather old, it is still in a good enough condition and no maintenance or rehabilitation works are required excluding offices of deputy of general manager of sanitation affairs, secretary and administration of technical studies and documentation.

The table below shows the needs the three offices.

4.2. Administration Buildings

Due to expansion in works and tasks in the departments of water and sanitation, administrations were constructed in every directorate in order to closely monitor works and tasks, manage operations, ease the process of income collecting and sort out complaints and problems. These administrations lack several office tools that are necessary for carrying out their duties. Additionally, office buildings in both Al-Mansoora and Al-Sheikh Othman require rehabilitation works. The table below shows the needs of the administrations in the directorates:

4.3. Maintenance Workshops

Given the fact that the PCWS owns machines, motors, pumps and equipment of various sizes and shapes that are prone to constantly break down and malfunction which mandates a need to perform maintenance works on these machines in order to have them available whenever needed, the PCWS established four maintenance workshops upon which befalls the task of performing periodic maintenance works on machines and equipment owned by the PCWS. Exemplary works of these workshops include oil, filters, tires and batteries changing, repair of any out of service machines or equipment owned by the PCWS. The work amongst these four workshops was assigned as follows:

Welding Maintenance Workshop: responsible for maintenance and repair works related to steel parts, welding and turnery works

Electrical Maintenance Workshop: responsible for maintenance and repair works related to electrical works such as fixing motors, pumps, generators, etc.

Mechanical Maintenance Workshop: responsible for maintenance and repair works related to mechanical works such as fixing vehicles, trucks, mechanical equipment, etc.

General Maintenance Workshop: this workshop is responsible for maintenance and repair works for all sewerage machines and equipment.

- 63 -

Despite the PCWS's great efforts in providing all necessary needs for the maintenance workshops, the financial challenges with which the PCWS struggles, especially low income, have caused the PCWS to become unable to perform rehabilitations works, such as renovation of buildings, supplying necessary tools, equipment and spare parts used in maintenance works on broken down machines, on these workshops.

In order to enabling the four maintenance workshops, the following requirements need to be supplied.

4.4. Occupational Safety Management

The corporation of water and sewer has a specialized department for occupation safety upon which falls the responsibility to provide safety equipment and tools as well as monitoring and observation of workers regarding following safety precautions and wearing safety gear. This department has several vehicles used for distributing safety equipment, tools and clothes and monitor the workers' commitment in this regard. Additionally, the department has many equipment and necessities designed to protect the workers upon performing highly risky jobs. Due to the damage of most of this department's equipment and tools, it urgently requires maintenance works for its vehicles and safety equipment that have been damaged. Moreover, due to the department's incapability to purchase safety equipment and clothes and distribute them among the workers, it has become rather urgent to provide safety equipment and clothes that are enough to cover all workers who practice activities that require wearing/using these equipment and/or clothes. The table below shows the needs for the occupational safety management

5. Water System

5.1. Wellfields

Well water (underground water) is considered the main water source for the city of Aden. The corporation of water owns 116 underground wells distributed among three main fields: Al-Manasera field with 29 wells, Bir Nasser's field with 46 well and Bir Ahmed's field with 41 wells

However, during the conflict period in the city, several of these wells have stopped working and the actual working number of wells that are currently in service is 106 wells with a well yield estimated at 123933 cubic meters daily.

The corporation has been determinedly working to increase the well yield of underground wells, a matter regarding which, noticeable results have been observed in recent years. In 2014, the actual well yield reached 114931 cubic meters daily, whereas it has now become 123933 cubic meters daily. This increase in the productivity rate is attributed to the number of wells established and rehabilitated by the corporation during the period from 2015 until now. Additionally, assistance offered by organizations which included providing the corporation with the fuel to operate the wells' pumps contributed in raising the productivity rate.

Despite the recent increase in the productivity rates of water, the administration of wells' fields is still facing many challenges and problems in more than one aspect, which can be surmised as follows:

Several wells went out of service due to the failure of more than 10 pumps as well as the malfunction of more than 15 step down transformers that are responsible for operating the pumps.

The corporation's incapability to perform maintenance works on the pumps as there are not any workshops that specialize in well pumps' maintenance.

Electricity related problems due to the weak power grid in the three fields. Therefore, it is very important to rehabilitate the power network in three fields in order to guarantee constant operation of the fields and minimize the loss in energy caused by the currently weak power network.

The corporation is currently struggling with many problems, the most important of which is the losses in water distribution networks. Due to damage of some parts of the network, water leakage occurs which requires the corporation to replace these damaged parts. Moreover, illegal and random connections as well as defected meters which deprive the corporation from earning income it needs desperately. Therefore, the corporation is working to replace old and damaged meters and disconnect all illegal connections. Additionally, the corporation aims to expand the water network in order to deliver water services to all parts of Aden.

5.4. Central Laboratory

The water department at the corporation has a specialized central laboratory (located at Al-Barzakh station) for running analysis and tests to monitor the quality of the water and whether it is viable for human use. Unfortunately, the water central laboratory with all its equipment and tools, including the chemical and bacteriological analysis devices were either stolen or damaged during the conflict the city witnessed. As a result, the laboratory no longer performed any analytical tests to monitor the quality of drinking water due to lack of equipment and tools. The laboratory was out of service for a while until it recently received several grants from various humanitarian organizations and local associates which rehabilitated the laboratory and provided the necessary tools and equipment. The table below shows the tools and equipment the laboratory has recently received.

5.5. Disinfection Units

In addition to the central laboratory, there are three disinfection units. One of them at the central laboratory and the other units are in the wellfields (Bir Ahmed wellfield and Bir Nasser wellfield). These units used to add chlorine compounds to the water before it is pumped and distributed in the network. Similar to the central laboratory, these units also went out of service since the beginning of the conflict in the city. These units were out of service until Mercy Cure organization provided temporary disinfection units that add chlorine to drinking water; however, these units are only a temporary solution that does not carry out water chlorination within the required amounts, which is why the disinfection units are still in need for three complete disinfection units along with their analysis devices as shown in the table below:

Notes Qty Requirements for disinfection units NO Supply and install three chlorine injection system

5.6. Water Pumping Stations

There are eight pumping stations in Aden city that supply water in the water network, one of which is a main station while the rest are substations.

Al-Barzakh Main Pumping Station

Slaughter house Minor Pumping Station

Al-Rawdhah Minor Pumping Station

Al Fatah Minor Pumping Station

Al Tahliah (Al Hiswa) Minor Pumping Station

Al Rowa Minor Pumping Station

Lahej-Tuban Minor Pumping Station

Al Aidroos Minor Pumping Station

The serviced areas in Aden city are supplied by the PCWS using the pressurized water distribution system as follows:

From Al-Manasera and Bir Nasser wellfields

Water is pumped from the wells located in Al-Manasera and Bir Nasser wellfields directly into two steel reservoirs, each with a capacity of 7500 cubic meters which are located in Bir Nasser wellfield. The water in these tanks is then pumped into one of these paths:

Directly into the distribution network which covers (Dar Sa'd, Al-sheikh Othman and some parts of Al-Mansoora)

Al-Barzakh station

From Bir Ahmed wellfields:

Water is pumped form the wells located in Bir Ahmed wellfields directly into two steel reservoirs, each with a capacity of 7500 cubic meters located within the same wellfield. The water in these tanks is then pumped into one of these paths:

Directly into the distribution network which covers some parts of Al-Mansoora.

The slaughterhouse station

From the slaughterhouse station:

The station receives water discharged from the reservoirs in Bir Ahmed wellfields and pumps it through eight different pumps into either the distribution network which covers Al-Sha'b city and some parts in Al-Boraiqa or Al-Barzakh station.

- 79 -

From Al-Barzakh station:

The station receives water from two main lines:

The steel reservoirs in Bir Nasser wellfield

The slaughterhouse station

The station pumps the water through six pumps into distribution reservoirs that cover the first region, which includes Khormaksar, Al-Tawahi, Al-Mu'alla and Crater.

The map in (Appendix 2) shows the water flow from the wellfields to the water distribution network passing through the pumping stations.

Due to the financial challenges with which the corporation has been struggling in recent years, it was not able to perform periodic maintenance on the main pumping stations and substation. This caused severe damage to the pumps and equipment at the pumping stations. As a result, the pumping stations need to obtain the spare parts necessary to maintain the pumps and equipment and have them back in service.

5.7. Operation and Maintenance Materials

Due to how various the operation and maintenance activities of the water department are, maintenance and operation tools and materials are of the most important assets on which the water sector depends to finish its tasks. Unfortunately, the water sector has lost a lot of its operation and maintenance tools and equipment, rendering it incapable of performing maintenance works, such as maintenance of wells pumps, generators, pumping stations, water network, reservoirs, etc. which caused many wells and pumping stations to go out of service. Additionally, the loss of operation tools caused the department of water to become unable to provide constant water supply; the corporation is not able to provide water supply for more than 3 days/week in some areas. On top of all that, this shortage in operation and maintenance tools and equipment prevented the corporation from being able to expand the water network and reach the deprived areas.

In order for the department of water to become able to perform its duties and provide satisfactory water services, the needs listed in Appendix 6.

6. Sanitation System

The establishment of the sewer system in Aden city went through many phases. Following is a brief illustration of each of these phases.

First Phase (Earlier than 1940): Sewage was discharged through canals which were constructed on the backways of the buildings. After that, sewage coming from these backways would reach manholes put at the end of each backway as shown in the figure.

Sewage gathered at the manholes would then flow into lateral, secondary and main waterways until it reaches sea coast. Seeing as how much see water pollution this system caused, the authorities decided to alter it. Building owners were committed to build basic screening chambers, each building had to have one, the outcome of these screening chambers would then flow across the canals which discharge water into the manholes.

Second Phase (1940-1963): In this stage, the use of Asbestos pipes began with pipes of no more than 24 inches as a replacement of canals. Also, main manholes were rebuilt using concrete as opposed to the masonry used in the old manholes. Additionally, stations of pumping and collecting sewage were established.

Third Phase (1980 – 1985): This stage is known for the establishment of the Kubota's project which improved the sewer network in the second region. The Kubota's project included rehabilitation of the old sewer network, the establishment of a new network for several areas which were denied sanitation services, rehabilitation and establishment of a few pumping stations and the establishment of the first treatment plant which received sewage from the second region and then treated it. It was in this stage that use of main pumping lines made from Ductile Iron with large diameters (200 – 800mm) began.

Fourth Phase (1985 – 1994): Adoption of clay pipes with diameters of 110, 160, 200, 250, and 300mm began in this stage. These pipes were used in all sanitation works of the sewer network, including new connections or replacement of damaged old connections which were made of Asbestos in all areas of Aden.

Fifth Phase (1994 – 2002): During this phase, several projects were carried out that improved the sewer network in Aden, including rehabilitation and expansion of the network in the first region and Al-Boraiqa, construction of Al-Areesh treatment plant which treats sewage coming from the first region as well as Salahuddin treatment plant for treating sewage of Al-Boraiqa and rehabilitation and establishment of several pumping stations.

The sewer network in Aden is currently struggling with many problems due to several reasons. The most important of these reasons are:

1. Damage of sewer network pipes as they have exceeded their expiration date and due to increase in amounts of wastewater discharged into these pipes as a result of the increase in population.

2. Misuse of sewer network by citizens, as is the case of disposing of kitchens' waste (grease) and sometimes some plastic-made objects through the sewerage both of which can lead to clogging and damage to the pipes and pumps of the network.

Since the crisis of 2011, not only was the corporation negatively affected, but also several equipment and maintenance and operation tools owned by the corporation were damaged. Additionally, the corporation underwent a financial crisis which rendered it unable to provide needs and costs of maintenance and operation.

All these factors caused the network to weaken to the point where sanity sewer overflow became a recurrent problem in some areas of the network. Following is a list containing areas where the network is most damaged and where sanity sewer overflow most occurs as well as areas the sewer network does not cover:

6.2. Manholes

The current sewer network comprises two types of manholes:

1. Main manholes

On the main lines of the network, main manholes are constructed. They are built using reinforced concrete and are isolated from the inside with a rubber layer in order to protect the concrete from the gases that erupt from the sewer water and are also isolated from the outside with a thick layer of tarmac.

2. Sub manholes

Whereas on the sub lines of the network, it is enough to construct manholes that are build using regular concrete and which are isolated from the inside with epoxy and from the outside with a thick layer of tarmac.

As for the manholes' steps, it was found that all the steps used are made of aluminum coated with a layer of zinc and are 185mm in length, which complies with the British specifications BS 1247 part 1.

Lastly, manholes' covers: two types of manholes' covers are used depending on their location:

On roads and public areas, heavy covers with the following specifications are used Heavy Duty Ductile Iron Manhole covers double triangular/circular ventilated cover with security screws. The depth not less than 150mm, clear opening 675x675mm, total mass not less than 150 Kg, the test load 40 tons. All the inspected covers are manufactured according to (BS EN124 Class-A D400-H).

On backways and interior areas, medium covers with the following specifications are used

Medium Duty Ductile Iron Manhole covers: square opening 600x600mm, integral seal provides odor-proof, the covers are secured using 4 screws and Push-fit seal plate, the depth 70mm, total mass not less than 110kg, the test load 25 tons. All the inspected covers are according to (BS EN124).

- 91 -

6.3. Pumping Stations

The city of Aden has 64 pumps; 36 of these pumps are in the first region while the second region has 28. The stations receive sewage from the network, which is later pumped to other main pump stations or directly into the treatment plants. Most these pumping stations were visited as part of the field assessment. Following are detailed assessments of the most important pumping stations the visits included:

Al-Tawahi Main Pumping Station

This station was established in April 2002. The station receives sewage from Al-Tawahi area and then pumps it across a pumping line into Al-Mu'alla main station. The station has 3 dry pumps 65 KW in power. The station is in a good condition, but requires a new generator to operate the pumps during grid blackouts. A specific room has been set up for the generator as the station had received initial approval from several organizations regrading providing a new generation. The station also requires rehabilitation works to be carried out on its administrative building which has become old and damaged.

- 92 -

Al-Mu'alla Main Station

This station was also established in April 2002 as part of Aden's sanitation project. The station receives sewage from Al-Mu'alla as well as sewage delivered from Al-Tawahi main station which it then pumps across a pumping line into Khormaksar main station. Al-Mu'alla station has 3 dry pumps 205 KW in power. Social Fund for Development (SFD) performed rehabilitation works on the station and provided it with its needs in 2018, and the current condition of the station is considered very good. However, the station struggles with electricity blackouts, more so since the backup generator requires maintenance works. Additionally, the basin of the station requires cleaning.

- 93 -

Crater Main Station

Crater main station was established in 2002 as part of Aden's sanitation project. The station receives sewage coming from Crater, which it later pumps across a pumping line into Khormaksar main station. The station has 3 dry pumps 90 KW in power. The station is currently out of service and has been so for longer than 5 years due to damage in the pumping line that delivers to Khormaksar main station. Details regarding the pumping line were included within the needs of Crater station.

- 94 -

Khormaksar Main Station

The Khormaksar station is considered the largest in the first region. It was established in 2002 and receives sewage delivered from all four directorates, which it later pumps into Al-Areesh treatment plant. Khormaksar main station has 3 dry pumps, two of which are 590 KW and the third is 132 KW in power. The station is in a very good condition.

- 95 -

Dar Sa'd Pumping Station

The station was established in January 1986 as part of the Kubota's project. The station receives sewage from the northern part of the Dar Sa'd sewage network and it then pumps it into college pumping station. The station has 3 dry pumps 150 KW in power. The overall condition of the station is very poor and it requires rehabilitation works as well as replacement of the pumps.

College Pumping Station:

The station was established in 1986 as part of the Kubota's project. The station receives sewage coming from some parts in Dar Sa'd directorate as well as sewage delivered from Dar Sa'd old station which it later pumps into Omar Al-Mokhtar station. The station has 3 dry pumps 200 KW in power. The station was rehabilitated in 2013 where one of the station's pumps was replaced. The station has been recently totally rehabilitated by the Emirates Red Crescent and is currently in a very good condition

- 96 -

Omar Al-Moktar Station

The station was established in 1986 as part of the Kubota's project. The station receives sewage from Al-Sheikh Othman as well as sewage delivered from College pumping station, which it later pumps into Al-Mansoora main station. The station has 4 dry pumps 250 KW in power. The station requires rehabilitation works for the building and the bathrooms as well as for the electrical wiring inside the station.

- 97 -

Hadjiv Station – Al-Mu'alla

The station was established in 2006. The station pumps sewage from the Hadjiv area into a down-sloping line – due to gravity – into Al-Mu'alla main station. The station has two small submersible pumps 16 KW in power. The station was rehabilitated by the SFD during the end of 2018.

Al-Fath Station – Al-Tawahi

The station was established in 2006. The station struggles with a major problem caused by the amounts of grease coming from the kitchens of the engineering provision services. The accumulated grease causes a lot of clogging and damage to the screen. The station pumps sewage of the Special Forces area into Al-Tawahi main station using two small submersible pumps of 9 KW in power. In addition to the rehabilitation works the station needs, it must be redesigned in proportion with the amounts of grease it receives.

- 98 -

Al-Kahraba neighborhood Station – Al-Mu'alla

The station is considered as one of the oldest pumping stations in Aden. It is currently out of service and has been so for over 5 years. The station requires full rehabilitation, including replacement of the old pump that is 2.2 KW in power.

From field visits and interviews with technicians and engineers at the pumping stations, operation problems of pumping stations which cause sanity sewer overflow in some areas can be surmised as follows:

1. Adoption of submersible pumps at many of the pumping stations as a modern system instead of using dry pumps, which turned out to be incompatible considering the conditions under which these pumps operate. Submersible pumps are used when the water being pumped is clear of any sediments or residues which tend to obstruct these pumps from operating properly, unlike how the water in the tanks at the pumping stations was found.

2. The absence of screening chambers at some of the stations, which are used to prevent sediments from flowing with the sewage, thus causing constant malfunctions of the pumps and sometimes leading to failure of the engines of the pumps.

3. Due to constant malfunctions of pumps as well as going many pumps out of service, backup pumps and spare parts became needs of great urgency.

4. Damage of some of the sensitive electrical spare parts on the operating panels due to humidity and gases erupting from the open tanks of the stations.

5. The absence of backup pumping lines at the sub pumping stations to discharge in emergencies.

The table below shows the needs of the pumping stations:

6.4. Treatment Plants

Up until the mid-eighties of the past century, sewage of the city used to be discharged through the main pumping stations directly into the sea causing significant harm to the marine environment. Consequently, the corporation started implementing effective measures of positive impacts on the environment, which included establishing treatment plants. This step did not only ensure against damaging the marine environment, but it was also beneficial in terms of providing irrigation sources for trees and plants in afforestation sites inside the city, which require treatment of sewage water per Yemeni and international specifications for treated wastewater used in irrigation purposes.

There are currently three treatment plants in Aden that receive and treat sewage coming from the sewer network and pumping stations and according to which the sewer network in Aden was divided into three areas as follows:

The north western area, which encompasses part of Al-Boraiqa directorate (Al-Sha'b city), Al-Sheikh Othman, Dar Sa'd and Al-Mansoora directorates. The sewage coming from these areas is discharged into Kubota's treatment plant.

The eastern area of Aden reaching the airport of Aden, which encompasses Crater, Al-Mu'alla, Al-Tawahi and Khormaksar directorates. The sewage coming from these areas is discharged into Al-Areesh treatment plant.

Sewage coming from Al-Boraiqa is discharged directly into the sea, except sewage that is brought in from Salah Aldien which is treated at Salah Aldien treatment plant.

All three treatment plants share the same operation method, which is explained as follows:

Screen: to separate large solids. Grit chamber is not applied because no mechanical parts exist and therefore no harm of accumulation of sand is expected at the anaerobic pond.

Anaerobic pond: acts in both ways, as a primary settling tank and for anaerobic treatment with a retention time that should not be higher than 5 days. In addition, the pond acts as a sludge digester through the anaerobic bacteria with a retention time of at least 2 months. The settled sludge at the anaerobic ponds is transferred to the drying beds.

Facultative ponds with 18 days retention times. BOD load is degraded by means of aerobic bacteria grown at the upper part of facultative ponds. BOD concentration at the outlet is expected to be further decreased in the maturation ponds which will also decrease the pathogen bacterial and helminth eggs.

6.4.1. Al-Mansoora Treatment Plant – Kubota

Established in 1985, Kubota's treatment plant is considered the first treatment plant to have been built in the city by the Japanese company Kubota. It receives sewage coming from the second region which is pumped through the main pumping station, the station in the industrial area in Al-Mansoora and the station in Al-Sha'b city, while the treated water is pumped into the neighboring natural reserve of Al-Hiswa.

The table below shows design details of Kubota's treatment plant

Value Unit Elements No 25,375 m3/day Hydraulic Load 1 5,535 kg/day Organic Load 2 123,000 No. Beneficiaries 3 360 mg/l BOD5 4 288 g/m3/day Volumetric Loading 5 290 kg/ha.day Surface Loading 6

106

The plant was designed in the early eighties of the past century with an allowable capacity of 20000 cubic meters based on the urban sprawl and growth standards determined then. However, the unexpected rise in population and structures which occurred after 1990 caused the volumetric and specific loads of wastewater brought into the treatment plant to grow exponentially, where the current actual load on the station is estimated to be around 35000 cubic meters, which means the station is overloaded with 140% of its design capacity. In addition, acts of robbery and theft of all editorial offices and laboratory's equipment during the last conflict the city of Aden witnessed caused the treatment plant to deteriorate and lessen its efficiency by 40%.

Following are detailed explanations of the current problems with which Kubota's treatment plant struggles

The absence of protection around the plant and weakness of the main gates which allows some animal and/or unauthorized personnel to enter to the basins area, which could pose danger to their lives.

The volumetric loading of anaerobic bonds is overloaded with 125% of the rated capacity.

Increase in the surface loading of facultative bonds is overloaded with 240% of the rated capacity which leads to: - Increase the growth of anaerobic bacteria - Decrease the efficiency of maturation bonds - Pollute the effluent of the plant.

107

Damage of the laboratory and editorial offices buildings at the plant and loss of all necessary tools and equipment.

In order to increase the plant's efficiency and improve the quality of the treated water used in irrigation and water of Al-Hiswa natural reserve, the plant requires the following needs shown in the table below:

6.4.2. Al-Arish Treatment Plant

In 2000, as part of Aden's sanitation project – the first phase treatment ponds were constructed for the second treatment plant in Aden located in Al-Arish area with an allowable capacity of 70000 cubic meters and receives sewage from the first region, which include Crater, Khormaksar, Al-Mu'alla and Al-Tawahi directorates. Sewage from these areas is pumped into Khormaksar main pumping station, which in turns pumps the sewage of the first region into Al-Areesh treatment plant.

The plant was designed in 1996 to receive sewage coming from the first region's directorates for 15 years (1998-2013) with the following design specifications:

The plant is made up of two operation lines. Each line consists of anaerobic pond, facultative pond and a maturation pond. Only one line is operated with a 35000 m3/day flowrate, 10920 Kg/day organic load and 312mg/l BOD5.

Value Unit Elements No 70,000 m3/day Hydraulic Load 1 21,840 kg/day Organic Load 2 240,480 No. Beneficiaries 3 312 mg/l BOD5 4 113 g/m3/day Volumetric Loading 5 382 kg/ha.day Surface Loading 6

109

The WWTP was totally damaged during the conflict where both the editorial offices building and laboratory were targeted by air force.

The plant was also neglected which caused ponds and canals to become clogged.

Currently, the treatment plant is out of service and the sewage it receives, it discharges directly into the sea without any treatment. With that said, the seawater is contaminated with 20000 cubic meters of sewage every day, which makes rehabilitation of the treatment plant extremely urgent.

110

In order to rehabilitate the plant and improve the quality of the water the plant discharges into the sea which could be used in irrigation of afforestation sites, the plant requires the needs shown in the table below

6.4.3. Salah Aldien Treatment Plant – Al-Boraiqa

After the establishment of both Kubota and Al-Areesh treatment plants, Al-Boraiqa became the only area where sewage was directly discharged into the sea. Therefore, the LCWS in cooperation with the SFD as the financer of the project established a treatment plant that would lessen the amount of wastewater being discharged into the sea. In 2002, Salah Aldien treatment plant was established which serves part of Al-Boraiqa directorate (Salah Aldien District) with an allowable capacity of 5000 cubic meters. This plant is considered as the last treatment plant to have been established in Aden city.

Salah Aldien treatment plant was designed in a basic manner where it contains only 3 ponds as follows:

Two anaerobic ponds with depth of 2.5m and capacity of 600 cubic meters.

Facultative pond with depth of 1.5m and capacity of 4000 cubic meters.

111

The plant does not own any editorial offices or laboratories. It also faces many problems, such as the unplanned urban sprawl on account of the area surrounding the ponds as well as clogging of ponds and canals as a result of not cleaning the ponds, which also lowered the plant's efficiency.

Because of the current condition of the plant, it has become surrounded with residential blocks from all sides causing the current location of the plant to become unsuitable and it is recommended that the plant is relocated somewhere away from the residential blocks and that it should be equipped with its own editorial offices and laboratory.

However, for purposes of rehabilitation the plant and having it back in service, the following needs are required:

6.5. Operation and Maintenance Materials

The department of sanitation lost a lot of its operation and maintenance tools during the period from 2011 until now. Due to the limited income the corporation manages to earn, it was not able to make up for this severe loss in equipment and machines.

The sanitation department has 12 sewage pumping stations and 17 sewage trucks most of which have become damaged and out of service. In addition, spare parts and backup pumps previously owned by the department of sanitation were subjected to acts of robbery and theft during the conflict the city witnessed. the table below shows the necessary equipment and machines for the corporation to become able to perform its operation and maintenance works successfully.
