Water Demand Assessment of Addis Kidam Town, Awi Zone, Amhara Region, Ethiopia

Abstract

Adequate quantity and quality of water demand is the most important for one town, as well as each individual to develop their economy in different aspects. The main objective of this study is to assess and provide sufficient and safe water demand of Addis Kidam town, Ethiopia. Existing water demand and sources of water supply is not sufficient for all types of demand at current time in study town, it requires more than half of addition water demand. The finding of this study exposed that, existing water supply has more problems, these are the rapid growth rate of population, lack of funding and loss of water leakages. The projected population of town for first and second phase is 37181 and 45640 respectively by using geometric increasing method.  Estimated demand of the town is based on types of mode of service and economic status of study area is 13796.84m³/d and 20423.36m³/d of maximum daily demand and 20971.2m³/d and 31043.51m³/d of peak hourly demand of the town for first and second phase respectively. The existing water source is covers only 33.5% and 22.63% of total current and future maximum daily demands of town communities of first and second phase. At current time needed additional water sources, which is 106.18 l/s and 183 l/s of maximum daily demand and peak hourly demand respectively to meet current water demand of town communities for first and second phase of design period. Capacity of services reservoir for first and second phase is 3000m³ and 5350m³ respectively throughout design period. Totally existing water sources and demand is not adequate quantity and quality for town population current and future time.
