ABSTRACT

This paper examined the management of water supply in Obantoko area (a typical Nigerian settlement. Population of the area was determined using building count method and satellite imagery while results of geophysical surveys of the area gave the indication of wield of prospective boreholes in the area. These were used to determine the costs and locations of prospective boreholes that will help maximize the use groundwater supply which is the most prospective water supply source in the study area. A map showing locations of boreholes to be sited and the population they will serve was produced. The study determined that with a population of 57,750 a total volume of 4,025,500 litres of water per day is needed in the study area. This volume of water could be produced from the study area if careful management of the water resources is done, the study concluded.
