This slide presentation outlines information on the International Water Audit Method. Advantages of the method are listed along with the IWA/AWWA Water Balance Format. Four components of managing real
losses are discussed and include: improved response time for leak repair; pressure management; active leakage control; and, improved system maintenance, replacement, and rehabilitation. Four components of managing apparent losses are discussed and include: unauthorized consumption theft and illegal consumption; meter accuracy error, meters do not register actual volumes passing; data transfer errors between meter and archives, poor customer accountability; and, data analysis, errors between archived data and data used for billing/water balance. Guidelines for Setting a Target Level
Infrastructure Leakage Index are given, along with AWWA Water Loss Control Committee
recommendations that include: the IWA methodology for the Water Audit and Performance
Indicators is recognized as the current best practice method
for quantitatively monitoring water consumption and water
loss in drinking water systems;
water suppliers should make use of the full array of
Performance Indicators included in the international
methodology; the term "Unaccounted-for" Water, having no consistent
meaning, be dropped from use in all industry references; and,
the four component approaches to controlling Real Losses
and Apparent Losses be utilized as leading practices to
economically control these losses. Includes tables.
