Rainwater catchment systems are low-cost, technologically simple water supply systems for use in rural and urban areas. The system itself usually consists of a catchment surface, delivery system and storage tank. In the case of a simple roof catchment system, the roof itself is the catchment surface, the gutters and drainpipe the delivery system, and barrels collect and store the runoff. Ground catchment systems consist of a sloped cement or treated earth area for harvesting rainwater, a stone and sand filter at the entrance to the drainpipe, and an underground storage tank. The quality of the water so obtained varies with each system, but if hygienic practices and routine maintenance are observed, the water can be used directly as drinking water. Several types of construction are outlined, including materials specifications, construction specifications, and procedures and economic considerations. Case studies from Africa, Asia and Australia are included.
