Design of a Water Supply Distribution Network Using Epanet 2.0: A Case Study of Maiduguri Zone 3, Nigeria

Abstract

Maiduguri Water Supply Scheme designed by its consultants in 1983 has divided the town into five water supply distribution zones. Zone 3 is one of three remaining zones in the city without a distribution network supplied from the Maiduguri water treatment plant. Consequently, residents obtain water from local water vendors, who retrieve the water from shallow boreholes which has proven to be tedious, cost ineffective and physically exhausting. A water supply network was proposed with the aid of EPANET software and the results obtained conformed to the design criteria established by the previous designers of the Scheme. A total water demand, projected for the year 2031 of 420LPS, minimum pressure head of 14.08m and maximum velocity of flow in the pipes of 1.24m/s was obtained. The use of EPANET software has proven to be time saving and its application is especially for the analysis of larger distribution networks is recommended.
