<br />Castle Rock Water Conservation Master Plan Backaround <br /> <br />Identifying where, when, and how water is used is critical to determining which <br />conservation measures will yield the most <br />reliable water savings for Castle Rock. <br />Water use consists of water consumed <br />for both indoor and outdoor purposes, <br />and therefore varies by region, climate <br />(including precipitation and rainfall), as <br />well as being impacted by socioeconomic <br />factors and other user characteristics. <br />Other applicable information that should <br />be considered when evaluating water <br />system demand characteristics related to <br />the condition and management of the <br />water delivery system itself. <br /> <br />Water Use Profile <br /> <br />"Identifying where, when, <br />and how water is used is <br />critical to determining <br />which conservation <br />measures will yield the <br />most reliable water savings <br />for Castle Rock." <br /> <br />By analyzing the current and historical water-use characteristics of each <br />customer category (single-family residential, multi-family, commercial, greenbelt, <br />irrigation, school and town), number of customers, indoor use versus outdoor <br />use, along with total, average and peak demand, an accurate water profile was <br />created. Having a thorough understanding of the amount and type of water use <br />taking place within each customer category today and in the future is vital to <br />development of programs that increase the efficiency of water use. <br /> <br />Use can also vary within each customer category. For example commercial <br />water use will vary with the type of business, whether retail sales, or restaurants, <br />hotels and Laundromats or car washes and breweries. Knowing whether there <br />may be more industrial users who and mayor may not use water for processing <br />is also important. For residential customers, use can vary not only by water use <br />habits, whether efficient or not, as well as by property size, type of landscape and <br />number of people in the household. <br /> <br />Water use is also influenced by <br />precipitation and temperature. <br />Castle Rock has a semi-arid <br />climate, averaging approximately <br />thirteen (13) inches of <br />precipitation per year. In the <br />summer, during hot or dry <br />weather, water use increases <br />approximately three hundred <br />percent hat of winter use, <br />creating an increase in demand on the water system, commonly known as peak <br />demand. <br /> <br />"Water use is influenced by <br />precipitation and <br />temperature... . <br />Castle Rock averages <br />approximately 13 inches of <br />precipitation per year." <br /> <br />TM-1 Background December 2006 <br /> <br />16 <br />
