The water demanded by property use type is summarized in <br />Table 1-2 below (WWE 2002). <br /> <br />Table 1-2: Water Demand by Property Use Type <br /> <br />Type of Property Use Potable Water Demand <br /> (gallons per capita per day) <br />Residential 85 gpcd <br />Commercial (general) 20 gpcd <br />Hotel 55 gpcd <br />Country Club 30 gpcd <br />Hospital 20 gpcd <br /> & 278 gallons/bed/day <br />School 18 gpcd <br /> <br />The ACWW A distribution system consists of ductile iron, asbestos cement and polyvinyl <br />chloride (PVC) pipelines, ranging in size from 6 to 30 inches in diameter. The ACWW A <br />distribution system is comprised of three pressure zones, the upper or Red Zone, the Grey Zone, <br />and the lower or Blue Zone. The Blue Zone serves the northern portion of ACWW A between the <br />ground elevations of 5,620 and 5,690 feet. The Gray Zone serves the southern portion of <br />ACWW A between the ground elevations of 5,670 and 5,880. The Red Zone serves the eastern <br />portion of ACWW A (east of Parl(er Road). The Blue Zone is supplied by gravity from a 1 <br />million-gallon storage tanl(, the Blue Zone Tanl(, which operates with a water level elevation <br />between 5,811 and 5,836 feet. The Gray Zone is served by a 4 million-gallon storage tanl(, the <br />Gray Zone Tanl(, which operates with a water level elevation between 5,947 feet and 5,970 feet. <br /> <br />A high demand booster pump station that draws from the Blue Zone Tanl( allows water to be <br />pumped to the Gray Zone. Additionally, there are several pressure reducing valves (PRV's) <br />between the two zones that allow the Gray Zone to download to the Blue Zone Blue Zone. There <br />is flexibility available in the distribution system so that some of the ACWW A wells may pump <br />into either the Blue or Gray Zone. <br /> <br />November 2006 <br /> <br />3 <br /> <br />Richard P.
