N’Djili, drinking water treatment plant rehabilitation in Kinshasa, Democratic Republic of Congo

REGIDESO SA is a commercial company that develops and manages the production, distribution, and commercialization of drinking water in 97 urban centers of the Democratic Republic of Congo. It has started a recovery program supported by the World Bank who has addressed the primary investment to three main centers, including Kinshasa. These centers are susceptible to generate additional resources that are essential to the financial balance of REGIDESO SA.

The IDA (International Development Association) has also given a grant to the Democratic Republic of Congo's government as additional financing for the Urban Drinking Water Supply Project.


The development objectives of this project are:

  • To sustainably increase the access to drinking water in three main target cities: Kinshasa, Lubumbashi, and Matadi, as well as the Kindu city
  • To improve the efficiency of REGIDESO by reducing water losses and increasing its productivity with the aim to improve its financial situation.

Under this context, our mission concerns the assessment for the rehabilitation of the N’Djili water treatment plant, connected networks and storage. Furthermore, three drinking storage tanks will be built in Gombele, Djelo Binza, and Kisenso.
