RAINWATER HARVESTING FOR DOMESTIC WATER SUPPLY IN DEVELOPING COUNTRIES: A LITERATURE SURVEY

Interest in rainwater harvesting @RWH") for water supply * in developing countries has grown with interest in supporting locally organized and implemented efforts to meet basic human needs. RWH is an attractive way of increas,ing the quantity of water available for household use in areas with water short-ages. Catchments using existing roof structures and surfaces, in combination with self-help built storage containers, repre-sent a particularly promising approach. The literature is reviewed; publications most useful to prospective designers and implementors of RWH projects are identified. Feasibility and costs assessment guidelines for simple RWH systems are given. Construction of selected catchment and storage technologies is described. When a small existing roof is used for catchment, several gallons per day could be provide
