Government of Uzbekistan, on behalf of the “Kashkadarya Suvoqava” has approached the European Bank for Reconstruction and Development (the “EBRD” or the “Bank”) with the request to finance a priority investment program (“PIP”) for rehabilitation of wastewater infrastructure (the “Project”) operated by the Company. The total population of the Kashkadarya Oblast is approx. 3.1 mln. people. State Unitary Enterprise “Kashkadarya Suvoqava” is 100% owned by the Ministry of Communal Affairs. The Company provides municipal services including water and wastewater services to residential customers, industries and organisations. The Company’s responsibilities cover the provision of services to the consumers is provided below. The “Kashkadarya Suvoqava” has the following subsidiaries: › Occupational district branch of the › Charakchi district "branch of “Suvoqava” "Suvokava" › Guzar district branch of the "Suvoqava” › Qoson district branch of the "Suvoqava” › Dehkanabad district branch of the › Karshi district branch of the "Suvoqava” "Suvoqava” › Nishan district branch of the "Suvoqava” › Mirishqor district branch of the "Suvoqava” › Yakkabog district branch of “Suvoqava” › Mubarak district branch of the "Suvoqava” › Kamashi district "branch of “Suvoqava” › Shakhrisabz Water Production Branch › Shahrizabz district branch of the › Talimarjan-Mubarak branch of water "Suvoqava” production › Qitob tuman "branch of “Suvoqava” › Karshi city "Suvoqava" branch According to the Company’s data, the total population provided with water supply services at the level of connection to the household is 451,692 people (2018), which is only 15% of the total population of the Oblast or 28% of the population living in the Company’s service area. The level of provision with a water supply connection varies from 80% in Karshi City to 5–10% in the rural settlements where connected water supply is available. Among the areas, with only decentralised sources, the worst situation is observed in Dehqonobod District where the population uses springs, channels and wells with low-quality and unsafe water. For water supply purposes, the Company uses both underground (77%) and surface sources (23%). The centralized wastewater system in Kashkadarya Oblast has been in operation since the 1970s and is provided in three cities – district centers: Karshi, Mubarak, Shahrisabz. The wastewater system is separated, it ensures the collection and transportation of household and industrial wastewater. There is KASHKADARYA OBLAST WASTEWATER MODERNIZATION PROJECT - FEASIBILITY STUDY Non-Technical Summary 1-6 no organized collection of storm runoffs. The total population of the Oblast is about 3.1 mln; of them, the population provided with wastewater services, according to the Company’s data, is 197,124 people (48,929 customers), which in percentage terms is only 6.3% of the total population of the region. The population in other settlements uses freestanding cesspools, pit toilets, septic tanks. The terrain relief has a continuous slope rising from west to east, therefore, wastewater disposal is performed mainly by gravity. There are 14 wastewater pumping stations (WWPSs) in Karshi, 5 of which are in a critical condition and are out of operation. All stations are manually operated. Operators on duty attend them day and night, manually turning on/off pumps depending on the level of wastewater in the receiving chamber. Screen chambers are flooded in order to reduce the frequency of the pumps starts. There are no bar screens on any of the WWPSs. Electrical and mechanical equipment is worn out. It was not possible to obtain reliable data on actual effluents inflowing to the pumping stations since there are no flow meters. The flows are estimated based on the running time of pumps and their design capacities. The total length of sewage networks in Karshi is 175.9 km. A major part of the sewage networks is made of reinforced concrete and asbestos-cement pipes. Breakdown rate on the sewage networks is persistently high, according to the data for the last three years, this is 4 breakdowns (including cloggings) per 1 km per year. Wastewater treatment is not performed in the cities of Karshi, Shahrisabz, and Mubarek as the existing treatment plants are in a critical condition. The design capacity of Karshi WWTP is 25,000 m3/day. The plant was put into operation in 1978, and aero-tank rehabilitation was performed in 2004. No treatment process is currently performed at the plant. Effluents run via capital structures of the screens, sand traps, then run through a by-pass channel bypassing the other facilities and are discharged into the collecting drain. Wastewater discharge is carried out 24 hours a day. It is not possible to obtain reliable data on actual flows since there are no flow meters at the inlet and outlet of wastewater. According to the Company, the average flow is 20,000-25,000 m3/day. To ensure the required degree of treatment the project provides for multi-stage, mechanical and biological treatment of incoming wastewater. The Project also assumes dehydration, post-treatment and maturing of the sludge. Tertiary treatment for nutrient removal is not required in line with the EU Urban Waste Water Treatment Directive, based on the capacities of the WWTP and absence of sensitive receptors. ESDD has concluded that a through connection of new customers to the wastewater system, accounting for and controlling the quality of wastewater entering the system, improvement of the wastewater treatment process (currently non-existent), the Project will reduce sanitary and epidemiological risks and adverse impacts on the environment and on water bodies. Construction and reconstruction of the existing WWTP will result in decreased H&S and environmental risks related to the use of wastewater leaks while allowing for the connection of at least 50,000 people and increased reliability. 1.1 Why the project in the water sector of Uzbekistan is needed? This Project is based on a technical, financial and institutional assessment of the wastewater treatment system of the area serviced by SUE “Kashkadarya Suvoqava”. It incorporates the technically and financially sound investments aimed at achieving a safe and reliable wastewater treatment to households residing in the project area in an environmentally and economically sustainable fashion. The objectives of the project are: › improvement of the Company’s operational efficiency (energy efficiency and resource efficiency); KASHKADARYA OBLAST WASTEWATER MODERNIZATION PROJECT - FEASIBILITY STUDY Non-Technical Summary 1-7 › reduction of operational costs; › improvement of services’ reliability and quality;
