<br />" <br /> <br />(advanced) according to the Water Conservation Guidebook published in 1993 by the <br />American Water Works Association. Below is the resulting calculation: <br /> <br />Average annual per capita use for Paris water system = 188.7 gpcd <br /> <br />Potential reduction in water use (Most Likely scenario) = (188.7 X 2%) = 3.77 gpcd <br /> <br />Potential reduction in water use (Advanced scenario) = (188.7 X 5%) = 9.44 gpcd <br /> <br />Technical Potential Savin!!s Range = 3.77 to 9.44l!DCd <br /> <br />V. Reducing Dry-Year Irrigation Water Use: <br /> <br />The TCEQ and TWOB have estimated that the potential savings for reducing dry- <br />year irrigation is between 10.5% (Most likely) to 20% (Advanced) of the dry-year water <br />demand in gpcd. These savings result from xeriscaping (using drought-tolerant, low <br />water demand landscapes) and decreasing watering of tradition landscaping by using <br />efficient watering methods. Below is the resulting calculation for Paris: <br /> <br />Paris dry-year demand = 208.1 gpcd <br /> <br />Paris average demand = 188.7 gpcd <br /> <br />Dry-year irrigation use = dry-year demand - average demand = 208.1 - 188.7 = 19.4 gpcd <br /> <br />Potential reduction in water use (Most Likely scenario) = (19.4 X 10.5%) = 2.04 gpcd <br /> <br />Potential reduction in water use (Advanced scenario) = (19.4 X 20%) = 3.88 gpcd <br /> <br />Technical Potential Savings Range = 2.04 to 3.88 gpcd <br /> <br />VI. Summation: <br /> <br />Calculation of the Total Technical Potential for reducing municipal per capita water <br />use is determined by adding the individual technical potential amounts in items I through <br />V above. The following table is a summary of these calculations for the City of Paris <br />water system: <br /> <br />8 <br /> <br />., <br />l;.;.'"' <br />
