The T~EQ uses 20.5 gpcd as the most reliable figure to represent the "most likely" conservatiqn scenario. This figure is based upon the estimate that by 2050, 900/0 of pre- 1990 hom~s, and all new homes will have been equipped with water conserving fixtures. I I The ~gure 21.7 gpcd is used as the "advanced" conservation scenario and is an estimate o~ the average savings that would result from homes equipped exclusively with water-consþrving plumbing fixtures. This figure is considered "advanced" because in a typical cit1, 100% of homes would not be exclusively equipped with water-conserving fixtures. ~esults ofTCEQ data yields the following estimations: "Most Lik, ly" Savings by 2050 = 20.5 gpcd "Advance4" Savings by 2050 = 21.7 gpcd I I Technical Potential Savin cd i , I I I I III. ReduJing Seasonal Water Use: I I The exas Water Development Board (TWDB) has calculated seasonal use as a percentag of average annual per capita use for East Texas (20%), West Texas (25%) and a statewid average of 22.5%. Seasonal use is calculated by multiplying the average annual gp d for each water system by the appropriate percentage. The technical potential for reducti n uses 7% for the "most likely" scenario and 20% for the "advanced" scenario. elow is the resulting calculation: Annual av rage per capita use for Paris water system = 188.7 gpcd I Geographilcallocation = East Texas Seasonal se = (188.7 X 20%) = 37.74 gpcd Potential r duction in seasonal use (Most Likely scenario) = (37.74 X 7%) = 2.64 gpcd Potential r duction in seasonal use (Advanced scenario) = (37.74 X 20%) = 7.55 gpcd Technica Potential Savin cd I I I IV. Redu~ing Water Use through Public Education Programs: The technical potential for water conservation through public education programs is estimated to be from 2% of the average annual per capita use (most likely) to 5% 7
