Paris dry-year demand = 208.1 gpcd <br />Paris Average demand = 188.7 gpcd <br />Dry-year irrigation use = dry-year demand - average demand = 208.1-188.7 = 19.4 <br />gpcd <br />Potential reduction in water use (Most Likely scenario) _(19.4 X 10.5%) = 2.04 gpcd <br />Potential reduction in water use (Advanced scenario) _(19.4 X 20%) = 3.88 gpcd <br />Technical Potential Savings Range = 2.04 to 3.88 <br />VI. Summation: <br />Calculation of the Total Technical Potential for reducing municipal <br />per capita water use is determined by adding the individual technical <br />potential amounts in item5 1 through V above.
