DESIGN OF WATER SUPPLY TREATMENT PLANT FOR GOVERNMENT RESIDENTIAL ESTATE AT ILESHA ROAD, AKURE, ONDO-STATE

Abstract

This study examines the present management and control of groundwater, stormwater and stream flow now in Government Residential Estate at llesha Road- Akure, Ondo State. The samples or these waters were collected for laboratory necessary analysis to determine their level of contamination and the treatment necessary them to human use for domestic water supply. The results or the laboratory analysis were analyzed and used to design a treatment plant for water supply for the study area. In order to get an efficient conveyance system for the stormwater flow and water supply in the study area, the topography or the area was studied and the spot heights or all the roads in the area were taken and their slopes determined. The results of these measurements and studies were used to design the drain channels and treated water piping networks. The population or the estate was calculated using the allocated plots and assumed inhabitants or 12, 12, and 8 per plot in the high, medium, and low densities areas respectively. (Note that the "density" here referred to the number of plots that makes a section of the estate.) These information and that of the rainfall depth or the area were used to calculate the various components or a treatment plant. There are two possible means of convenient water supply to the estate; these are the construction of a treatment plant in the estate or the extension or the public water supply pipe to the estate. However, the construction or a treatment plant is suggested because the public water supply is not reliable. The economic implications of all available systems were assessed to show their financial involvement and this shows that it will cost N144,323,000.00 to provide the present system or water supply by the inhabitants while Government will provide N635,000,000.00 for the proposed treatment plant and N475,000,000.00 for the public-water distribution system.
