AWWA ACE61661

Based on statistical analyses of a dataset created from the California Urban WaterConservation Council (CUWCC) website, this study confirms some familiar but notwidely-applied perceptions that include: water-loss management programs can increase revenue andsave resources during a relatively short payback period; metering systems are a veryimportant tool for water management including water-loss control; big systems are likelyto lose more water in the distribution systems; and, water rate systems can be an effectivepolicy tool in encouraging water conservation and discouraging water waste and loss. This study tests the following two hypotheses in an empirical model.Hypothesis 1: the more expenditures on water-loss control, the less water lost.Hypothesis 2: the quantity of water loss is likely to be a function of various factors suchas system size, population served, water rates, production costs, customer mix, meteringrate, water produced, and other operational factors. This study calculates water loss by subtracting the sum of metered sales (revenuewater) and other system verifiable uses (authorized uses) from total supply into thesystem (total water produced). To test the hypotheses, this study analyzes a model, using linear regression. Themodel is the following:dependent variable = amount of water loss;independent variables = expenditures on leak-control programs, miles ofdistribution system, service area population, total number of accounts metered, totalnumber of accounts un-metered, revenue from volumetric rates/ total deliveries percustomer type (residential, commercial, industrial, institutional, and irrigation). Includes 7 references, tables, figure.
