Abstract

Despite its existence for several centuries, the development of rainwater roof catchment system faces great difficulties in African countries. particularly in the Sahel. Obstacles for its expansion include the scepticism and uncertainty of local populations concerning the safety of rainwater when store for long time.

In order to promote this technology in African co ntries, CREPA and CIEH have established a program for construction of rainwater c tern systems throughout Ouagadougou in Burkina Faso. Also, CREPA has extended his program to include all other countries which are members of the Centre through demonstration projects. At the samr time, CREPA examines regularly the water quality during conservation. According to WHO standards, rainwater stored is drinkable Sometime , pollution due to animals is noticed. But, the lack of organic matters in stored rainwater precludes the growth of micro-organisms

In conclusion, when well constructed, the rainwater cistern system can be an alternate source of water supply.
