<br />Castle Rock Water Conservation Master Plan Backaround <br /> <br />Analysis of seasonal water production <br />patterns reveals that over fifty (50) <br />percent of water produced within a year <br />is used during summer months for <br />landscape irrigation. Average winter <br />demand is increased three to four times <br />during the summer. <br /> <br />Over 50% of annual <br />production is used for <br />landscape irrigation. <br /> <br />Water Production History <br /> <br /> Peak Day Production Date <br />2000 8,015,600 July 28th <br />2001 11 ,821 , 1 00 June 30th <br />2002 9,036,100 August 4th <br />2003 10,848,900 July 12th <br />2004 9,731,500 July 9th <br /> <br /> Average Day Production <br />2000 3,7 MGD <br />2001 4,5 MGD <br />2002 4,6 MGD <br />2003 4,8 MGD <br />2004 4,5 MGD <br /> <br />In Castle Rock, water production is less than actual demand. Peak demand is <br />met with the assistance of storage. In 2005 peak demand was more than 16 <br />MGD. <br /> <br />Distribution System Evaluation <br /> <br />Potable Water Demands <br /> <br />As potable water demands increase, additional water treatment and distribution <br />system improvements must be made to sustain reliable service to existing <br />customers as well as serve new development. Although the Town's overall <br />potable water demand has increased steadily since 1998, the average <br />demand per account has decreased significantly. <br /> <br />The reduction in water usage per account since 2002 is most likely attributable to <br />the public's response to the recent drought and the Town's focus on conservation <br />efforts. The Town's demand per account in 2004 and 2005 was about 430 <br />gallons per day per account, down from a historical high of 565 gallons per day <br />per account. <br /> <br />TM-1 Background December 2006 <br /> <br />18 <br />
