Water and Sanitation Lease and Affermage Contracts

For a useful summary of affermage and lease contracts and when they are used, go to the PPIAF Gridline - Using Management and Lease/ Affermage Contracts in Water Supply (2006).

Hybrid affermage/ Concession contracts

In the water sector in recent years in West Africa, a hybid affermage/ concession arrangement has been adopted - a description of such an arrangement in Cote d'Ivoire can be found at PPIAF Gridlines - Partnering for Water in the Cote d'Ivoire(lessons from 50 years of successful operation). Examples of the hybrid model that has been adopted are set out below. A summary of the institutional and contractual structure adopted in a project in Senegal is set out here. A more detailed discussion of the Senegal affermage arrangement can be found at Innovative Contracts, Sound Relationships - Urban Water Sector Reform in Senegal Water (pdf).

Below are a number of samples of these hybrid affermages/ concession structures:

  • Cameroon - details of the affermage contract (contrat d'affermage) for urban and peri-urban water supply. The affermage is for a term of 10 years commencing in May 2008 and covers 106 urban and peri-urban centres. The affermage is between CAMWATER (Cameroon Water Utilities Corporation) which is a state owned asset holding company and CDE. CAMWATER in turn holds a concession with the State of Cameroon for the provision of water services in Cameroon. Attached to the contract at annex 6 is the contrat de performance (performance contract) between the State of Cameroon, CAMWATER and CDE. For further details in English and French go to the CDE web site.
  • Niger - A summary of the legal and institutional framework in the water sector, and the challenges facing the sector, in Niger can be found in a Report of the International Secretariat for Water (Pour la mise en place de Mecanisme de Cooperation Decentralises Au Niger)
