Name of Client: Ernst and Young (EY) Uzbekistan/Joint Stock Company Uzsuvtaminot Status: Ongoing (completion date - 13/01/2023)
Narrative description of Project: Uzsuvtaminot JSC plans to provide safe drinking water for 2.2 million people of Surkhandarya province by constructing a rising main from the Tupalang reservoir. To this end, a preliminary project has been developed, which involves the construction of a structure in the lower part of the Tupalang reservoir to dampen pressure, purify and distribute water, from which 361 km of pipelines will be laid to water distribution units. The capacity of the facility will be 200,000 cubic meters per day. The implementation of this project involves an investment of around $350 million until 2025. Existing drinking water supply system provides access to centralized or semi-centralized drinking water to 1,6 mln people, or 58.6% of the population of the region with number of connected households 235 742 pcs, and legal entities 3 417 pcs. Water supply system composed of pipelines—8 579km, pump stations—146, water reservoirs—279, water distribution stations—84 and employees working in this sector—1080 people. Upon implementation of the project, expected capacity of the water supply system is planned to increase to 248 m3/hour, connecting additional 480 000 people, reaching the coverage ratio of 71% in Surkhandarya province. The project is planned to be implemented under PPP mode involving a private partner implementing the project. The project envisages: ● Rehabilitation of existing WDUs and water treatment plants, networks and other facilities relevant for water supply of the whole province; ● Implementation of innovative solutions, including automatic control system, control and measuring equipment (SCADA), GIS and hydraulic modeling, pressure sensors, electronic flow meters, electrochemical protection of pipes.
