Objective and Purpose of the Assignment
The proposed Climate-Resilient Water and Sanitation Services Project aims to improve the public health
and economy in Fergana, Andijan, Djizzak provinces and Republic of Karakalpakstan through sustainable
and efficient delivery of water supply and sanitation (WSS) services to 100% of the regional population
and addressing a set of challenges related to climate change, environmental pollution, energy
efficiency, operation and maintenance capacity, and public-private partnership investments. These
measures in turn will strengthen the livable environment by ensuring access to affordable and reliable
WSS services for about 3.2 million residents in the project areas, particularly in two districts and
three cities in Fergana, four districts and one city in Andijan, and one district in Djizzak provinces.
The project outputs are:
Output 1: Climate-resilient WSS infrastructure expanded. The project will finance upgrades of WSS
systems in nine districts and five cities in the Republic of Karakalpakstan and the provinces of
Andijan, Djizzak, and Fergana, thereby expanding water resources availability and preserving the quality
of water sources to cope with increasing climate-induced water scarcity; climate mitigation measures
will also be taken and implemented to protect the infrastructure from extreme climate events. Output 1
will include water supply augmentation facilities through the rehabilitation of one water treatment
plant (WTP) with a capacity of 140,000 m3/day, and the construction of one WTP with a capacity of
200,000 m3/day, 352 km of water supply transmission mains pipeline, two water distribution centers
composed of two booster pump stations and four water reservoirs; bulk water supply meters will be
installed at the main water sources locations. Output 1 will also expand wastewater systems through the
construction of five WWTPs with a combined capacity of nearly 40,000 m3/day, 347 km of sewerage
networks, and on-site sanitation options following the concept of city-wide inclusive sanitation.
Facilities for re-use of treated water and sludge will be constructed and O&M services for the plants
will be embedded in the construction contracts. Supervisory control and data acquisition (SCADA) and
asset mapping through a geographic information system will also be implemented.
Output 2: Institutional capacity of suvtaminots improved and sustainable WSS services delivery
strengthened. The physical investments will be complemented by strengthening the operational and
management capabilities of regional suvtaminots on (i) leak detection, repair, and preventive WSS system
maintenance; (ii) DMA development and NRW reduction; (iii) analysis of consumer consumption and
recommendations for reducing commercial losses; and (i) preparation of a business plans for suvtaminots
that covers technical, operational, institutional, and organizational restructuring; and human resources
management (iv) energy efficiency—in conjunction with the capacity building activities and the IT
foundation system being established under the Climate-Smart Water Management Improvement Project. The
targeted training will be provided for technical and managerial staff of suvtaminots in various
specialized areas, with a particular focus on female employees. Moreover, the project beneficiaries
will engage in public awareness campaigns on water conservation, health, sanitation, and climate
adaptive water-saving practices. A pilot NRW program through a DMA approach in a selected area will be
implemented to demonstrate the benefits of improved O&M practices. Training and support for the
operation of the plants will also be provided in coordination with the activities carried out by O&M
contractors.
The transaction technical assistance (TA) grant will support the recruitment of consultants to help the
government to (i) conduct a comprehensive review of the existing status of the WSS service delivery in
the proposed project areas; (ii) complete physical assessments of the existing WSS infrastructure; (iii)
propose solutions and conceptual designs; and (iv) prepare project due diligence technical analysis and
safeguard reports and loan package documentation.
Scope of Work
The national Water Supply and Sanitation (WSS) Specialist will work in coordination with the national
senior WSS specialist on: (i) confirmation of approach adopted for improvement of water supply
infrastructure under the proposed project in: (a) Andijan and Fergana, (b) the Republic of
Karakalpakstan, and (c) Djizzak, (ii) formulation of hydraulic modelling for proposed bulk supplies; and
(iii) site visits and technical review of the water supply/wastewater collection systems including
preparation of hydraulic technical review report and other aspects related to the project activities.
Detailed Tasks and/or Expected Output
The consultant will work closely with the Team Leader and the international technical team, and the
national senior WSS specialist and undertake the following tasks:
(i) support the technical preparation and review of technical reports for the proposed project
components and in particular those in relation to augmentation of bulk water supply. This will include
confirmation that the proposed surface water sources are sustainable and offer the best value for money
solution (over potential ground water sources);
(ii) conduct site visits, and support the team in performing technical review of existing and proposed
expansion of the water supply and wastewater treatment and collection systems in the project areas; and
identify and collect information required for the work during site visits;
(iii) liaise with Uzsuvtaminot and other government authorities such as Hydrogeology, Water Resources,
Statistic, etc. in obtaining the necessary information;
(iv) review existing relevant plans and studies, and provide technical evaluation of the proposals
contained therein – as appropriate and necessary;
(v) support the formulation of hydraulic computations and conceptual design scenarios (pipe sizing, pump
requirements, etc.) for the optimization of the proposed bulk water supply, water treatment and
distribution plants and wastewater collection and treatment systems;
(vi) establish hydraulic profiles for the bulk water supply and wastewater collection networks as well
as of the treatment plants and related facilities;
(vii) verify the adequacy of the existing networks to convey the potable water and wastewater flows to
and within each catchment area and to the treatment plants;
(viii) optimize the size water distribution pipelines and of trunk sewer pipes and collectors;
(ix) support the Project team leader, deputy team leader and international wastewater specialist in
designing at conceptual level the bulk water facilities, water treatment plants and wastewater treatment
infrastructure and other related investment required in the project towns.;
(x) liaise with and support the other members of the team to assess the cost (investment and operation)
of the proposed options for the bulk water supply inlet and transmission works, water pumping and
storage facilities WTPs and WWTPs and related water and sewerage system infrastructure and facilities;
(xi) provide inputs as needed for the selection and dimensioning of pumps and pumping equipment;
(xii) support the calculations for the optimization of water transmission mains, reservoirs and
elevated tanks as necessary;
(xiii) prepare layouts of network systems; and
(xiv) provide inputs to technical reports as needed.
