| Abstract: | ABSTRACT The majority of houses in Nigeria do not have direct connections to water supply mains. These households obtain water from public standpipes for their daily needs. Presently, the criteria which are employed to locate the standpipes are not clearly defined. A new approach using simulation techniques is proposed for finding the number and location of public standpipes, so as to improve the efficiency of water delivery services. In a case study of the Alanamu ward in Ilorin, it was found that 17 standpipes are optimal to provide a 100% service level for a population of 42,000 people. The maximum service distance would be 650 m roundtrip Economically nearly N96,000 [N = naira, N1.00 = $0.25 U.S.] in annual income foregone would be saved when 10 standpipes are added to supplement the existing 7 standpipes in the ward. The annual investment cost of N1,250 for installing and maintaining the new standpipes is small compared to the savings that would accrue to the community. |
