Objective and Purpose of the Assignment

Proposed project. The project will develop an integrated wastewater management system in six cities, one
urban center, and 70 rural settlements in three districts in Tashkent Province. It will provide
inclusive access to centralized sewerage to more than 800,000 people in urban areas, and access to
decentralized sanitation systems to 136,000 people in rural areas. The project will also help establish
TST as a model utility for replication in other provinces.

The main outputs are:

Output 1: Inclusive urban and rural sanitation systems with climate-resilient features developed. This
output includes: (i) centralized urban wastewater systems in the six cities of Akhangaran, Almalyk,
Angren, Bekabod,Chirchik, and Yangiyul and Chinaz urban center improved, by (a) rehabilitating and
upgrading of four WWTPs, and constructing of one new WWTP, with a combined capacity of 392,000 cubic
meters (m3/day); (b) rehabilitating and constructing 114 kilometers of sewerage collectors and 238
kilometers of sewerage networks with new sewer connections; and (c) installing 50,000 water meters and
1,028 bulk water meters; and (ii) decentralized wastewater systems in 70 rural settlements in Chinaz,
Yangiyul and Zangiota districts established by: (a) installing 23,500 individual septic tank systems;
(b) providing O&M equipment; (c) operationalizing TST fecal sludge management unit;
(d) formulating fecal sludge management program to rationalize and expand septage collection and
disposal services; and (e) implementing a public WASH+H awareness program.

Output 2: Institutional capacity for sustainable sanitation services delivery strengthened. This output
includes capacity development of Tashkent Suvtaminot (TST) through corporate development training and
coaching in business planning; corporate governance; asset management; human resource management,
including gender policies and sensitization training, financial management, customer relationship
management, technical wastewater management, O&M management, and environmental monitoring. In addition,
treatment plant managers and O&M operators in the project areas will receive training provided by design-
build contractors
