ASSESSMENT OF WATER CONSUMPTION PATTERN IN ILORIN, KWARA STATE, NIGERIA

Abstract

This report presents the outcome of a survey of water use pattern in Ilorin, Kwara State. Nigeria. The water use pattern study extends to various water consumers such as residential, institutional, commercial and industrial. The study was conducted through questionnaire survey and oral interview which centered on water demand and uses. Most residents were found to use between 46 to 115 l/c/d. The high rates were common in low density areas and the low rates in medium and high density areas of the city. The daily values for commercial, industrial and institutional facilities sampled within the metropolis were 75,535; 188,735 and 161,680 litres respectively. Moreover, public water distribution system is not adequate, because majority of consumers still source water from wells or boreholes to meet their basic needs. Some mathematical models have been generated which could be used to estimate water need for planning and operational purposes. The results of the models show that water use by some categories of consumers can be estimated knowing certain variables and coefficients.
