<br />Castle Rock Water Conservation Master Plan Backaround <br /> <br />EXISTING WATER TREATMENT, STORAGE AND <br />DISTRIBUTION SYSTEM <br /> <br />The Town draws water from the Dawson, Denver, and Arapahoe aquifers <br />through a system consisting of thirty-six raw water wells. These wells pump <br />water to four major water treatment plants for the removal of iron and <br />manganese, as well as chlorination disinfection. Finished water pumps located <br />at each of the treatment plants pump finished water to the Town's seven <br />pressure zones that comprise the distribution system. Nine booster pump <br />stations, fifteen storage reservoirs, and fifty-six pressure regulating valves are <br />located throughout the distribution system to serve customers within Town <br />established level of service performance criteria. Figure 1 shows the geographic <br />location of the Towns water infrastructure and key information related to these <br />faci I ities. <br /> <br />The Town also has seven alluvial wells, which are located near East Plum Creek <br />and Seller's Creek. These wells currently are out of service due to water quality <br />issues. The long-term plan is to utilize this water to meet a portion of the Town's <br />water demands. <br /> <br />The Town's current water treatment capabilities meet state and federal <br />regulations and no further improvements are needed to meet future regulations <br />that are currently anticipated. <br /> <br />In September of 2006, the Town adopted its updated Water Facilities Master <br />Plan. This report outlines existing system criteria and inventory, and describes <br />planned improvements to Castle Rock's water treatment and distribution system <br />infrastructure to provide service to existing and future development through build- <br />out of the Town's current service area boundary. <br /> <br />Figure 3.1 depicts existing water infrastructure, and Figure 3.2 depicts the <br />existing water system schematic. <br /> <br />TM-1 Background December 2006 <br /> <br />8 <br />
