Project General Description

The Multi-Use Water Supply Reinforcement Project along the Keur Momar Sarr base station has been designed to provide water management for multi-use in the Louga, Thiès and Dakar regions. It is part of the Bank’s intervention to the overall project “Construction of a third treatment plant in Keur Momar Sarr”. This project is one of the Senegalese Government's priorities as part of its new strategy to facilitate access to drinking water for rural and urban populations. In addition to providing populations with a better access to drinking water and strengthening the area's industrial activities, the project will also strengthen the development of support activities for the production and marketing of agricultural products. Its implementation is planned for a period of 4 years, with an overall cost estimated at 423.84 million euros. The project’s expected main outputs are: (i) the construction of a third water treatment and pumping plant in KEUR Momar Sarr (KMS3) with a production capacity of 100,000 m³, expandable to 200 000 m³ per day; (ii) the installation of a pipeline between the plant and the town of Thiès, and between Thiès and Dakar, for a distance of about 216 km; (iii) the construction of two (02) storage tanks of 10 000 m³ each in Thiès; (iv) the construction of three (03) distribution tanks in Thiès, at Blaise Diagne International Airport (AIBD) and Diamniadio; (iv) the installation of structural supply and distribution networks for a linear length of 182.4 km; (v) the completion of 792 km of network extensions, and the supply and installation of 85,000 social connections; (vi) the construction of infrastructure to support production and marketing of agricultural and vegetables products; and (vii) the development of an IEC Program to raise awareness about water issues.

Project Objectives

The project’s assigned objectives are part of the Senegalese authorities’ main concerns, namely: (i) cover the drinking water and industrial needs in the Louga, Thiès and Dakar regions, with particular emphasis on the communities bordering Lake Guiers by 2025; (ii) strengthen multi-use water supply in the project area; (iii) ensure a balanced financing of the urban water subsector.
