Case Study

Urban Senegal

After an international competitive bidding process a tripartite Public-Private-Partnership contract was signed in 1996 for ten years. It was renegotiated in 2006 and 2013 and extended until the end of 2018. The scope of the private operator is to produce and supply water on a daily basis using the infrastructure that is owned by SONES. It is an “a[ermage” since major investments are funded by SONES. The main shareholder of SDE is Eranov with 57% of the shares. The population currently supplied by the contract is close to 5.5 million inhabitants.

The contract is a performance-based contract. The outputs targeted are monitored by a very comprehensive “performance contract” signed with SONES. The numerous performance indicators cover all operational processes including, the quality of water supplied, the quality of services (speed of reaction to customer complaints and requests and to service interruptions), technical aspects as well as ]nancial performance. SDE with its partner SONES has managed to deliver signi]cant improvements to the water supply service.
