Abstract:
Kombolcha is one of the rapidly growing towns in Ethiopia. Problems of adequate water
supplies and reduction of non-revenue water remains one of the major challenges facing
Kombolcha water supply system. This study is focus to assess the total water loss in the
distribution network using water audit software V 5.0 and domestic water supply coverage
using Mathematical analysis. A Mathematical analysis was applied to analyze the current
domestic water supply coverage of the entire town. And also water meter test was conducted
for samples from each brand of meters installed in the distribution system of the town in
order to quantify the water loss through meters of under registration. Water audit software
was also used to analyze water loss components and the efficiency of the system was
evaluated using different performance indicators. Discussions were made with Local experts‟
to support the quantitative analysis. From the result of the analysis, it was identified that the
average daily per capital water consumption of the town is 44.03 liter/person/day. Nearly
26% of the total water production is lost at different level of distribution system before
reaching to the town consumer. The main reasons for the high loss of water in Kombolcha
water supply system use poor maintenance and insufficient financial resources of the utility.
