<br />Raw water demands for irrigation purposes at the golf course and FLC are currently approximately 582 <br />acre-feet per year based on an irrigated area of 194 acres. Future irrigation demands at FLC and the golf <br />course are projected to be 732 acre-feet per year as the irrigated area of Fort Lewis College is expected to <br />increase to around 244 acres. Peak day irrigation demands are currently 1.7 mgd and are expected to <br />increase to approximately 2.1 mgd in the future. <br /> <br />The current demands placed on the water system are very close to the maximum raw water delivery capacity. <br />In fact, the current peak day demand is approximately equivalent to the delivery capacity which means that <br />water from storage will be required to satisfY peak day demands above current projections. The next table <br />shows a comparison of the delivery and treatment capacity of the water supply system with current and <br />projected water demands. <br /> <br /> <br />and Demand Com arison <br /> <br /> <br />Current Water Delivery Capacity <br />- Peak Day Treated Demand <br />- Peak day Non-Potable Demand <br />Water Delive Ca aci Excess (Deficit) <br />Current Water Treatment Plant Design Capacity. <br />- Peak Day Treated Demand <br />Water Treatment Ca aci Excess (Deficit) <br /> <br />· Water Treatment Plant has a peaking capacity of 14 mgd (Goff Engineering 1985) <br />· In 1981, Black & Veatch rated plant capacity at 14 mgd. <br /> <br />Since the current water delivery system is being used at maximum levels during peak period and Durango is <br />experiencing a fairly rapid growth rate, the City will be required to construct additional raw water delivery <br />and water treatment facilities in the future. <br /> <br />Demand projections were also determined for drought restricted conditions assuming the implementation of <br />the City's Water Shortage Management Plan. Demands during droughts were projected to be equal to in- <br />house use plus 75% of outside irrigation requirements. <br /> <br />The average monthly demands shown below were calculated using water usage figures from the period 1980 <br />through 1993. <br /> <br />Avera e Monthl Unconstrained and Drou ht Restricted Demands <br />Month Unconstrained Treated Demands Drought <br />(acre- feet) <br /> <br />lanuary <br />February <br />March <br />April <br />May <br />lune <br />July <br />August <br />September <br />October <br />November <br />December <br />Annual Total <br />Peak Da <br /> <br /> <br />Demands <br /> <br />18,000 <br />250 <br />222 <br />246 <br />282 <br />399 <br />516 <br />516 <br />436 <br />355 <br />311 <br />2350 <br />246 <br />4,033 <br />9.4 m <br /> <br />VI.
