DESIGN OF A WATER SUPPLY SYSTEM IN ONGATA RONGAI

Abstract

The purpose of this project was to design a water supply system for Ongata Rongai. Ongata Rongai is one of the fastest growing towns in Nairobi’s Metropolitan area. The water supply system in the area therefore needs to be upgraded to meet the ever increasing demand from both the domestic and industrial use.

The report therefore outlines the steps taken to collect the data needed for the design which includes use of questionnaires, interviews and literature documents. It goes a step ahead to show how the data collected was analyzed to get the demand of the area. The data collected also gave an overview of water shortage in the area and the different ways in which water is utilized. The main trunk line from the Kiserian dam, which is the source, was then designed together with a distribution network for only a portion of the area. This was because the discharge from the source was not adequate to meet the demand of the area. The profiles of the designed pipelines were then plotted.
