this paper describes the potential use of household rainwater collection to provide drinking water for rural areas of sri lanka, where water supply presents severe problems. rainfall data from five climatically different regions are analyzed, and it is shown that the water requirements for drinking and cooking can be satisfied without the need for unduly large storage; it is assumed that traditional sources would continue to be used for bathing. the average incremental costs are high, varying between us $1. 00 to $1. 42 per cubic meter. the data presented are currently being used to start up a small pilot program in sri lanka, in which one of the main aims will be to ascertain householders' response to rainwater collection a great advantage of household rainwater collection is that maintenance is the responsibility of householders, and not of a government agency.
