| dc.description.abstract | Losses in the urban water supply networks have become a growing concern and there are several alternatives for the quantification, detection and monitoring of water losses. However, water loss is a great challenge in developing countries including Ethiopia as well as Debre Brehan town. Peoples do not have enough access to safe and reliable water coverage due to highly water loss in the distribution system and other utility problem. Therefore, this study mainly focuses on to assess the status of water supply coverage and water losses in Debre Brehan town. Statistical analysis with regards of field observation, different literature revision, pressure measurement and discussions with water service personnel were conducted to analyze the water supply coverage and water loss in the town. Water CAD software was adopted to examine the hydraulic parameters and water supply elements in the distribution network. The finding of this study showed that the average connection per family and average daily per capita water consumption of the town was estimated in the order of 32% and 23.24 l/c/d respectively. As water loss estimation result from the total production of water in the town about 37.40% of is non-revenue water. Among this, 6.78% is real loss that includes leakage and pipe burst. Whereas, 30.62% was apparent loss more considerable and accounted for meter inaccuracy, poor maintenance practice, legal unbilled connection and illegal connection. Moreover, from the model analysis result different problems were observed. These were poor efficiency of pumps and storage tanks, high and low pressure beyond to the recommended value. In general, the main reasons for the low water supply coverage of town was poor water network management, lack of attention and budget to develop additional water source, high level of water loss and low performance of the existing distribution system. Thus, well organized network management practice, giving more attention to water loss and reduction strategies, constructing additional source of water and installing standby generator at all existing pump station are some important remedial measures to improve the water supply coverage of the town. | en_US |
