Hydraulic Performance Of Urban Water Supply Distribution System A Case Study At Sekota Town Water Supply Project, Ethiopia

Abstract

The life of an individual is directly related to water. Inadequate water supply, unsafe water resources and inequitable access of water consume time, increase disease and costs of health facilities. This will finally lead to poverty in the area. The water distribution system is an essential component of every water utility. Its main function is to provide a safe, reliable water supply at an acceptable level of service and water distribution networks. This research focuses on evaluating the hydraulic performance of urban water supply distribution system of Sekota Town which was designed by the two consultants of Amhara Water Works Construction Enterprise (AWWCE) and Amhara Design and Supervision Works Enterprise. To assess the water supply distribution coverage of Sekota Town, to evaluate the water demand in Sekota Town and to evaluated the hydraulic performance of the existing design of the distribution system network using Water CAD v8i model This research findings and to make the workload easy materials are play vital role. The materials are used Computer, Flow meter, Stationary, Topographic map - to determine geographic location, elevation etc. Were set. The scope of this study was on confined the factors which affect the hydraulic performance of the pressure line and distribution system when water flows from source to customer. Generally the outputs showed that the network is exposed to relatively low values of pressure and velocity, which has negative effect on the performance of the network. In assessing the water supply distribution coverage and the distribution network for the Town and determining its hydraulic performance, WATER CAD v8i software has to be used. The study resulted that an increase in loss of hydraulic reliability during water flow directly affects water quantity, the existing design of water distribution network of the Town should be redesigned and hence this deduction gives room for developing the town in all directions, as the municipality is not clear about the future industrial zone and development area of the town. The water supply distribution coverage was 11.39 l/p/d. the Sekota Town Water consumption is found much lower compared with other developing towns. Therefore additional water supply should be constructed in order to increase water supply coverage of the Town. In addition, during the implementation of the distribution system the reservoir has to be increased at list to one third of the maximum day demand of the Town and proper sized pipes be used. Besides discussion with the concerned administrative and executive bodies is found necessary for the present and future development target areas of the Town
