ANALYSIS OF BIDA WATER DISTRIBUTION NETWORK NIGER STATE, NIGERIA

Abstract

Bida Town is undergoing rapid expansion and lack adequate supply of potable water which has given room to the use of different water sources and sometimes results in outbreaks of water borne diseases. EPANET system analysis of Pipe Network was used to analyze the distribution network for both present and future demand after collation of the population data, pipe lengths and diameters, elevation and water demands. EPANET is a computer program based on Hardy cross method of water flow analysis that performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks. The study has shown that the present situation of Bida distribution network is inadequate in meeting the demand of the consumers, as the outcome of the simulation shows negative pressures in 5 of the nodes while 9 of the pipes has low velocity and 10 pipes recorded high headloss. Areas affected by these inadequacies are those along loops 6 and 7 which include G.R.A, Ramatu Dangana axis and along Bida Town Hall on Ahmadu Bello way. Corrective measures were, however, outlined based on the results. These include modification of diameter of some pipes, provision of thrust blocks and installation of washouts. Future design period of 30 years was also considered and analyzed. Both hydraulic and urban development measures should be used to address inadequacies in the distribution system under future scenario.
