This powerpoint presentation begins by providing a diagram of where our water goes, and then lists different types of water losses. A figure is provided that illustrates the Contribution of Billed Volumeby Meter Size, and statistics are given for a Small Meter Accuracy Study that illustrates the impact that small meters have on apparent waterlosses. A figure is provided that presents the results of an AWWA Research Foundation Residential End Use Study - Phoenix Data Set in terms of percentageof volume passed at each flow rate range, and a comparison is provided of Flow Allocations by Range forComposite Accuracy Calculation. Findings show that:meter make appears to be the most importantfactor influencing accuracy; and,there is not a strong correlation between meterage or total volume flowed and accuracy. Figures are presented for Potential Water Loss from5/8" Meters; Potential Annual Loss of RevenueBy Meter Make; and, Annual Revenue Loss Per MeterBy Meter Make.
