Water Supply Systems in Blue Nile Health Project

Abstract

Improvement of domestic water supplies is a major component of the comprehensive strategy for control of water‐associated diseases in the Blue Nile Health Project of central Sudan. The value of safe water supply was confirmed in a study in 1981 that showed an inverse relationship between the rate of consumption of safe water and the prevalence of diarrheal disease and bilharzia for villages with central supplies. Proposed improvements in water supplies would cost about $0.64/person annually in 1984 prices, to raise the consumption from the original 40 L/person/day to a design goal of 70 L/person/day. Analysis of preconstruction data indicated that these modest improvements should cause significant reductions in water‐associated diseases.
