Objective and Purpose of the Assignment
The proposed Climate-Resilient Water and Sanitation Services Project (CRWSSP) aims to improve the public
health and economy in Fergana, Andijan and Djizzak provinces and Republic of Karakalpakstan through:
(i) sustainable and efficient delivery of water supply and sanitation (WSS) services to 100% of the
regional population; and (ii) 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 province.
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 adaptation 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 from the Andijan reservoir in Andijan region, 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. A NRW
program through a DMA approach in a selected area of the existing network will be implemented to
increase efficiency of the system. 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 wastewater 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 CSWMIP. 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. Training and support for
the operation of the plants will also be provided in coordination with the activities carried out by O&M
contractors. Support for the assessment and monitoring of water balance and quality of water extraction
in the Andijan reservoir will be also provided to ensure the water source sustainability.
The transaction technical assistance (TA) grant will support the recruitment of consultants to help the
government: (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 Specialist will work on: (i) review of current WSS system
provision and needs in the Project areas; (ii) site visits and technical review of the water supply and
wastewater collection systems including preparation of hydraulic technical review report (as necessary)
and other aspects related to the project activities; and (iii) formulation of hydraulic modelling.
Detailed Tasks and/or Expected Output
The consultant will work closely with the Team Leader and other international and national technical
team members in undertaking the following tasks:
(i) conduct site visits and support the team in performing technical review of existing and proposed
expansion of the water supply, water treatment, wastewater treatment and collection systems in the
project areas; and identify and collect information required for the work during site visits;
(ii) support demand calculations and analysis to help in identifying scope and scale of proposed water
supply and wastewater sub-projects;
(iii) 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;
(iv) review relevant existing plans and studies for water supply and wastewater system expansion and
improvement and provide technical evaluation of the proposals contained therein – as appropriate and
necessary;
(v) support the technical preparation and review of plans and reports outlining the scope and scale of
proposed project components for: (i) water supply network replacement and additional pipelines; and (ii)
sewer network replacement and additional pipelines;
(vi) support the formulation of hydraulic computations and conceptual design scenarios (pipe sizing,
pump requirements, etc.) for the optimization of the proposed water supply transmission and distribution
pipelines and water supply treatment systems;
(vii) support the international and national wastewater specialists in designing at conceptual level the
wastewater collection systems and treatment infrastructure;
(viii) support the calculations for the optimization of reservoirs and elevated tanks, wastewater
collection systems and ancillary works;
(ix) provide inputs as needed for the selection and dimensioning of pumps and pumping equipment;
(x) establish hydraulic profiles for the bulk water supply and wastewater collection networks as well as
of the treatment plants and related facilities;
(xi) prepare layouts for proposed expanded and rehabilitated network systems;
(xii) 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, wastewater collection networks, WTPs and WWTPs and related water and sewerage
system infrastructure and facilities; and
(xiii) provide inputs to technical reports as needed.
Minimum Qualification Requirements
The WSS Specialist (national, 4 person-months) will have a graduate degree in civil engineering,
engineering science, mathematics science or related fields or equivalent; and work experience and
demonstrated expertise in hydraulic modeling and preliminary engineering design for water supply and
sanitation sectors, and of at least one water supply and one wastewater project in Uzbekistan.
