<br />n. Reducing Indoor Water Use due to Water-Conserving Plumbing Fixtures: <br /> <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 /> <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 ofTNRCC data yields the following estimations: <br /> <br />"Most Likely" Savings by 2050 = 20.5 gpcd <br /> <br />"Advanced" Savings by 2050 = 21. 7 gpcd <br /> <br />Technical Potential Savin~s Ran~e = 20.5 to 21.7 I!pcd <br /> <br />m. Reducing Seasonal Water Use: <br /> <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 of22.5%. 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 the "most likely" scenario and 20% for the "advanced" scenario. <br />Below is the resulting calculation: <br /> <br />Annual average per capita use for Paris water system = 188.7 gpcd <br /> <br />Geographical location = East Texas <br /> <br />Seasonal use = (188.7 X 20%) = 37.74 gpcd <br /> <br />Potential reduction in seasonal use (Most Likely scenario) = (37.74 X 7%) = 2.64 gpcd <br /> <br />Potential reduction in seasonal use (Advanced scenario) = (37.74 X 20%) = 7.55 gpcd <br /> <br />Technical Potential Savin~s Ran~e = 2.64 to 7.55 I!pcd <br /> <br />7 <br />
