Water Conservation Goals for Estimation of Potential Reduction in Per Capita Water Use throu2h the Year 2050 The following tables for potential reduction in per capita water use were initially calculated in 1999 for the original adoption of the Water Conservation Plan in 2000. The Utility Survey form and instructions were provided by the Texas Commission on Environmental Quality (TCEQ) for municipal water conservation planning through the year 2050. The conservation measures establish a bottom range or "most likely" real world potential conservation scenario and an upper range or "advanced" scenario that assumes ideal situations representing a maximum achievable conservation savings. A range of potential savings is determined for each of the following conservation measures: 1. Reducing unaccounted-for water uses; 2. Reducing indoor water use due to water-conserving plumbing fixtures; 3. Reducing seasonal water use; 4. Reducing water use through public education programs; 5. Reducing dry-year irrigation water use. I I. Reducþtg Unaccounted-for Water Uses: The ~CEQ considers unaccounted-for water uses (loss) of 150/0 or less acceptable for communit es serving over 5,000 people. Losses above 15% provide a conservation potential ith greater losses providing a greater potential. The bottom of the range for technical ~otential savings is zero. Calculation of the top of the range is determined by the followtng table: I I I Unaccoun ed-for uses = 15.9% i Dry-year I er capita water use = 208.1 gallons per capita per day (gpcd) Potential or reduction in unaccounted-for use = (208.1 gp d X 15.9%) - (208.1 gpcd X 15%) = 33.09 - 31.22 = 1.87 gpcd Technica Potential Savin cd II.
