Water Conservation Goals for Estimation of Potential Reduction in Per Capita Water Use throul!h the Year 2050 The following tables were derived from data accumulated in the Utility Survey performed for the City of Paris water system. The Utility Survey form and instructions were provided by the Texas Natural Resource Conservation Commission (TNRCC) 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: t. 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. Reducing Unaccounted-for Water Uses: The TNRCC considers unaccounted-for water uses (loss) of 15% or less acceptable for communities serving over 5,000 people. Losses above 15% provide a conservation potential with greater losses providing a greater potential. The bottom of the range for technical potential savings is zero. Calculation of the top of the range is determined by the following table: Unaccounted-for uses - 15.9% Dry-year per capita water use = 208.1 gallons per capita per day (gpcd) Potential for reduction in unaccounted-for use = (208.1 gpcd X 15.9%) - (208.1 gpcd X 15%) = 33.09 - 31.22 = 1.87 gpcd Technical Potential Savin~s Ran~e = 0 to 1.87 gpcd 6
