I (advanced) ¡according to the Water Conservation Guidebook published in 1993 by the American Water Works Association. Below is the resulting calculation: I i , Potential re uction in water use (Most Likely scenario) = (188.7 X 2%) = 3.77 gpcd cd Average ual per capita use for Paris water system = 188.7 gpcd Potential r uction in water use (Advanced scenario) = (188.7 X 5%) = 9.44 gpcd Technical I V. RedUC~g Dry-Year Irrigation Water Use: The CEQ and TWDB have estimated that the potential savings for reducing dry- year irrigat on is between 10.5% (Most likely) to 20% (Advanced) of the dry-year water demand in cd. These savings result from xeriscaping (using drought-tolerant, low water dem d landscapes) and decreasing watering of tradition landscaping by using efficient w tering methods. Below is the resulting calculation for Paris: Paris dry-y ar demand = 208.1 gpcd Paris avera e demand = 188.7 gpcd Dry-year i .gation use = dry-year demand - average demand = 208.1 - 188.7 = 19.4 gpcd Potential r duction in water use (Most Likely scenario) = (19.4 X 10.5%) = 2.04 gpcd Potential r duction in water use (Advanced scenario) = (19.4 X 20%) = 3.88 gpcd cd Calcu ation of the Total Technical Potential for reducing municipal per capita water use is dete ined by adding the individual technical potential amounts in items I through V above. e following table is a summary of these calculations for the City of Paris water system: 8
