This paper begins by providing a brief overview of two
major categories under which all types of supplier water loss occurrences fall. Apparent
losses are essentially "paper" losses and consist of customer use which is not recorded
due to metering error, incorrect assumptions of unmeasured use, or unauthorized
consumption. Real losses are defined as the physical escape of water from the
distribution system, and include leakage and overflows prior to the point of end use. The hidden costs of real losses are discussed, along with potential health risks from leakage and breaks, a 2001 Awwa Research Foundation (now known as the Water Research Foundation) report titled "Pathogen Intrusion into the Distribution System" that studied infiltration under two conditions, and an example of using performance contracting to optimize water loss by the City of Kingsport, Tennessee. Includes table, figures.
