EVALUATION OF QUANTITY OF WATER SUPPLY IN MINNA METROPOLIS

Abstract

The quest for portable and safe drinking water has continued to be a challenge to most Governments of West Africa. Since its inception in 1976, the state water board constructed three treatment plants in minna metropolis, the last been in 1992 with a total capacity of 77mlpd including Bosso treatment plant to cater for a population of 193,300. This volume is expected to fill all the eight storage elevated tanks per day. The aim of this paper therefore is to provide Analysis and hydraulic evaluation of the supply system considering an increase in population, rise in living standard of the populace and rapid urbanization. Remote Sensing was used in the Estimation of demand and karman- Prandtl- Colebrook Nomogramm was used for pipe sizing. The studies revealed the capacity of the tanks to be insufficient and were even underutilized primarily due to connections from the transmission mains. The study also identified the inadequacy of transmission pipes’ internal diameter, and therefore concludes by recommending for a re-design of the system.
