AbstractWater loss from water distribution systems is a major concern to water utilities. Water utilities around the world are becoming more focused on adopting a proactive approach to managing water loss. The amount of lost water can be significant, reaching levels as high as 50% of production. However, water loss management is still not widely practiced by utilities in North America. Water balance analysis is the most widely used method for quantifying water losses. Guidelines and standard procedures for performing water balance analysis is mainly provided as a best practice (BP) document by the International Water Association (IWA). Experience shows that successful implementation of this BP depends to a large extent on the ability to efficiently collect and integrate data from various sources. These data sources include metered and un-metered consumption records, water supply data, and water network asset inventory. It will also require an understanding of various components contributing to the water loss, and the significance and inter-relationships of computed performance indicators (PIs).
