<br />Town of Castle Rock <br />Water Conservation Plan <br /> <br />The Town's wastewater flows are an integral part of water planning. They are used <br />for irrigation, and augmentation discharge requirements. <br /> <br />(7) Currently, the Town has agreements for the use of up to 600 acre feet per year of <br />treated wastewater with Castle Pines and Castle Pines North for the irrigation of two <br />golf courses. The Town also has an agreement with Cedar Hill Cemetery <br />Association to supply up to 60 acre feet per year of treated wastewater effluent for <br />the irrigation of several acres. Due to the lack of local wastewater treatment, reuse <br />water is not being supplied to the cemetery at this time. Obligations are currently <br />being met by raw water. Once the use of reuse water becomes feasible to meet the <br />Cedar Hill commitments, local reuse will be pursued. <br /> <br />(8) The Town has six pressure zones defined by elevation. These zones are connected <br />through pressure reducing valves and booster pumps. Operational strategies are <br />aimed at meeting average and peak demands. The Town has ten water treatment <br />plants, six water pumping stations, and ten potable water storage reservoirs. There <br />are currently approximately 5,000 service connections to the water distribution <br />system. <br /> <br />(9) The Town's water is under specific testing parameters as required by the Colorado <br />Department of Health through the Colorado Primary Drinking Water Regulations. <br />Generally, even the Town's raw water meets the drinking water standards, however <br />water is treated for aesthetic purposes to lower elevated levels of iron and <br />manganese. <br /> <br />(10) The Town identifies its supply needs by defining a relative measure of demand <br />placed on the potable water, effluent or reuse and wastewater capital plant of the <br />Town by an average single-family residential, or single family equivalent (SFE). An <br />SFE, or one housing unit, serves 2.8 people. These values are based upon the <br />relative size and capacity of the potable water connection. The value of 0.5 acre <br />feet/year is used for planning purposes in supplying one SFE. <br /> <br />(11) The Town's water rates are based on a inclining scale, with a base rate of <br />$lO/Month/SFE, and $1.00/1,000 gallons for 0-5,000 gallons of water used, <br />$1.50/1,000 for 5,001-15,000, and $2.00/1,000 for 15,001+. <br /> <br />(12) The average water use from 1990 through 1994 is approximately 175-180 gallons per <br />capita per day. The average maximum day peaking factor (Average Day Usage/ <br />Maximum Day Usage) of 2.65 has been adopted, with a maximum system wide peak <br />hour factor of approximately 4.5. <br /> <br />6 <br />
