<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />for construction at the earliest possible date is shown on Plate II. The <br /> <br />system consists of 8-inch and 6-inch mains with some 4-inch and 2-inch <br /> <br />connections into the existing system. The size of pipe, valve locat~ons, <br /> <br />and hydrant locations are shown on Plate II. Distribution mains are sized <br /> <br />to deliver fire flows and are integrated with the existing mains to the <br /> <br />maximum extent possible. When construction is completed as shown on Plate <br /> <br />II, fire flows exceeding 750 gallons per minute can be achieved in the <br /> <br />residential areas that are currently developed. Along the new mains and <br /> <br />in the Town's business district, fire -flows of 1750 to 2000 gallons per <br /> <br />minute can be delivered. <br /> <br />Fire hydrants will be spaced to provide an average area per hydrant of <br /> <br /> <br />approximately 140,000 square feet. All materials used in the distribution <br /> <br /> <br />syst~ will be conventional water works materials as approved and recommended <br /> <br /> <br />for use in public water systems by the Colorado Department of Health, the <br /> <br />U.S. Public Health Serivce, and the Americanlvater Works Association. These <br /> <br />materials are readily available from numerous sources. Delays due to manu- <br /> <br />facture, fabrication, and transportation are not anticipated. <br /> <br />The water supply well pumps will be connected directly to the distribution <br /> <br />mains. Pumps will be equipped with pump control valves to reduce pressure <br /> <br />surges in the mains when the pumps start and stop. Storage tanks levels <br /> <br />will "float" on the distribution system and "water hannner" is not expected to <br /> <br />be a problem. All bends, tees, crosses, valves and hydrants, and plugs shall <br /> <br />be provided with adequate thrust blocking. The distribution mains and appur- <br /> <br />tenances will be flushed, sterilized and pressure tested prior to being placed <br /> <br />in service. <br /> <br /> <br />The hydraulic characteristics of the distribution system including the <br /> <br />sizing of mains and the delivery of required fire flows is based on a Williams <br /> <br /> <br />and Hazen Formula C value of 130. The pipe materials to be used will have a <br /> <br />-39- <br />
