    <subfield code="a">&lt;p&gt;Water loss management is the indicators of water supply structure management for effective water demand management. Water supply service scarcity was a reoccurring concern in the study area&amp;rsquo;s water supply system, despite the presence of water supply source capacity. The objectives of this study are to evaluate water loss, to evaluate hydraulic performance and to indentify possible engineering measures to control water loss. The annual production and consumption were the secondary data collected for water loss analysis using water balance and top-down approach methods. Water source capacity, pipe size, service reservoir capacity, junction demand and elevation were the major input data for hydraulic performance analysis using waterGEMS CONNECT EDITION update 2. Water loss performance, hydraulic performance and the existing water supply structure situation were the engineering measures impact considered for problem identification to propose possible engineering measures to control water loss for effective water demand management. 46.4 percent of unaccounted for water, 19 percent of junctions covered by above maximum allowable pressure of 70m pressure head during maximum consumption hour, and 85 percent of junctions covered by above maximum allowable pressure of 70m pressure head during minimum consumption hour hydraulic performance were indicators of the existing engineering measures impact. Pressure management, active leakage control, speed quality maintenance, and asset management were the identified engineering measures to conrol water loss for effective water demand management&lt;/p&gt;</subfield>
