Objectives:

The project aims at covering the deficit in meeting the demand for drinking water expected to occur in the city of Nouakchott in the year 2023 and meeting the future demands of its residents until the year 2034, through the rehabilitation of existing wells and the digging of new wells in Idini aquifer basin and collecting and transferring the water from these wells to the city’s reservoirs, along with the strengthening of some existing facilities, which were completed within the framework of the Aftout Coastal project. The project also aims at utilizing the Idini aquifer basin as a strategic water reservoir which can cover about 50% of Nouakchott’s demand in the year 2025, and about 35% in the year 2035, in case of a long-term interruption in supply of water from the Aftout Coastal facilities.

Description:

The project, which is expected to be completed by the end of the first half of 2025, consists of the rehabilitation and digging of underground wells and equipping them, the laying of pipelines, raising the capacity of the existing primary water treatment station in Beni Naji, the expansion of the existing water filtration station near the city of Nouakchott, the strengthening of pumping stations belonging to the Aftout Coastal project, the establishment of water reservoirs, and the setting up of a monitoring and control system in the Idini wells system. The project also includes the provision of the necessary technical services to prepare the studies, designs and bid documents, as well the assistance in bid analysis and supervision of project implementation, along with providing institutional support to the project’s implementation management and the company. The project includes the following main components:

1. Facilities to Secure Water Supply to the City of Nouakchott from the Idini Basin:This includes the rehabilitation of about 46 existing wells in Idini Basin, in addition to digging about 16 new wells, and equipping those all those wells with submersible pumps with capacities of about 100 m³/hour and head of about 120 m, and the execution of all the necessary civil, hydromechanical and electrical works to operate the wells. This component also includes the laying of pipelines to collect the well water with total lengths of about 45 km, and diameters ranging between about 200 and 700 mm, the construction of a reservoir in Idini with a capacity of about 2500 m³, another reservoir in the city of Nouakchott with a capacity of about 5000 m³, and the laying of pipelines to transport water to the city with a length of about 59 km and diameter of about 1200 mm, in addition to the setting up of a monitoring and control system at the Idini well system.
2. Strengthening Aftout Coastal Water Facilities:This includes raising the capacity of three pumping stations with capacities ranging between 2090 and 3290 m³/hour and head ranging between about 8 and 143 m, raising the capacity of the existing primary treatment station for water from the Senegal River in Beni Naji from about 170 thousand to 255 thousand m³/day, raising the capacity of the existing water filtration station near the city of Nouakchott from about 150 thousand to 225 thousand m³/day, constructing two water reservoirs, each with a capacity of about 5000 m³, and the laying of pipelines with a length of about 14 km and diameter of about 1200 mm.
3. Technical Services:This component includes the necessary consultancy services to prepare the project’s studies, designs and tender documents, and assist in call for tenders and bid evaluation, as well as the supervision of the project implementation, and the conduct of any additional studies necessary to achieve the project goals.

Financing:

The Arab Fund’s loan covers about 60.0% of the total project cost. The Mauritanian government will cover the remaining cost of the project and any additional cost that may arise.
