Abstract
Urban water supply and consumption challenges are the widespread problems in most of the
developing countries such as Ethiopia. The thesis paper focused on the water supply system of Emdibir
town, capital city of Cheha Woreda Guraghe zone of Southern Nation Nationality People Regional
State of Ethiopia.
The main objective of this study was to assess the water supply systems of Emdibir town and to suggest
some remedial measure. The water supply coverage has been evaluated by depending on the amount of
water production and consumption rate.
The existing water distribution system was analyzed by using Water GEMS software. The model can
be used to identify the zone of high pressure and low pressure in junctions and the level of velocity
through pipe. In addition, sample pressure filed data used to compare with the computed value.
The analysis result has confirmed that the current water supply coverage of the town is 63.3 % of
maximum daily demand. The current average per capita water production is 24.71/c/day. From one year
production and consumption data the average loss become 21.4%. There are aged pipes, oversized and
undersized pipes, high pressures and low pressure, high gap between demand and supply, pump
capacity problem in the system.
The study concluded that the total water demand and the current level of water supply service in the
town are not adequate.
Therefore, taking these challenges into consideration, it was suggested that providing alternative water
sources, active involvement of the communities and participation of different actors and other
sustainable approaches would prove to be an effective and efficient adaptive measures.
