sic <br />1I. Reducing Indoor Water Use due to Water - Conserving Plumbing Fixtures: <br />The TNRCC uses 20.5 gpcd as the most reliable figure to represent the "most likely' <br />conservation scenario. This figure is based upon the estimate that by 2050, 90% of pre - <br />1990 homes, and all new homes will have been equipped with water conserving fixtures. <br />The figure 21.7 gpcd is used as the "advanced" conservation scenario and is an <br />estimate of the average savings that would result from homes equipped exclusively with <br />water - conserving plumbing fixtures. This figure is considered "advanced" because in a <br />typical city, 100% of homes would not be exclusively equipped with water - conserving <br />fixtures. Results of TNRCC data yields the following estimations: <br />"Most Likely" Savings by 2050 = 20.5 gpcd <br />"Advanced" Savings by 2050 = 21.7 gpcd <br />Technical Potential Savings Range = 20.5 to 21.7 <br />III. Reducing Seasonal Water Use: <br />The Texas Water Development Board (TWDB) has calculated seasonal use as a <br />percentage of average annual per capita use for East Texas (20 %), West Texas (25 %) and <br />a statewide average of 22.5 %. Seasonal use is calculated by multiplying the average <br />annual gpcd for each water system by the appropriate percentage. The technical potential <br />for reduction uses 7% for (lie "most likely' scenario and 20% for the "advanced" scenario. <br />Below is the resulting calculation: <br />Annual average per capita use for Paris water system = 188.7 gpcd <br />Geographical location = East Texas <br />Seasonal use = (188.7 X 20 %) = 37.74 gpcd <br />Potential reduction in seasonal use (Most Likely scenario) = (37.74 X 7 %) = 2.64 gpcd <br />Potential reduction in seasonal use ( Advanced scenario) = (37.74 X 20 %) = 7.55 gpcd <br />Technical Potential Savings Range = 2.64 to 7.55 <br />7 <br />
