Extension of the existing water supply system in Niamey

Summary

The drinking water system of Niamey, with a capacity of 110.000 m³/day, needs to be extended in order to meet the increasing demand of the growing population and to reach new neighbourhoods. The project includes a new water treatment plant with a capacity of 40,000 m³/day and the reinforcement and extension of the transmission and distribution network. This additional drinking water production will meet the demand until 2021. ORIO provided a grant for the Development Phase of the extension of the water supply system of Niamey. The Agence Française de Développement (AfD) and European Investment Bank (EIB) intend to co-finance the implementation of this project.

Development Phase

The capacity of the raw water intake in the Niger River has to be increased by rehabilitating a currently abandoned raw water intake. Next to the construction works for the new water treatment plant (Goudel IV), additions will be made to the existing pre-treatment facility and pumping station, including a new disinfection contact chamber for disinfection and pH correction, a new chemical building, new high lift pumps and a new emergency generator. The drinking water transmission and distribution network has been expanded many times and has a somewhat erratic layout. A distinction can be made between transmission pipes and distribution pipes. In general, water is transported through transmission pipes to reservoirs spread through the city from the pumping stations at the treatment plants. Distribution pipes are connected to the reservoirs from where drinking water is supplied to customers. Especially in the older parts, distribution pipes are also directly connected to the transmission pipes. The existing network will be improved and extended with additional transmission pipes, reservoirs, distribution pipes, individual connections and stand pipes.
