<br />. <br /> <br />e <br /> <br />. <br /> <br />IV. <br /> <br />City of Arden Hills <br /> <br />services constructcd. Each unit will be assessed at the determined rate for <br />each size and number of serviccs installed. This will be known as the <br />building service assessment. <br /> <br />WATER DISTRIBUTION SYSTEM IMPROVEMENTS <br /> <br />A. Definitions <br /> <br />1. Water Source and Treatment Facilities <br />The City of Arden Hills purchases water from the City of Roseville to <br />supply the water distribution system. Water enters the system at three (3) <br />separate meter stations. <br /> <br />The water purchased from Roseville is treated, and Arden Hill does not <br />add any water treatment to the distribution system. <br /> <br />2. Water Storage Facilities <br />The City of Arden Hills has a total water storage capacity of 1.5 million <br />gallons comprised by two (2) elevated storage tanks. One tank has a <br />capacity of 1.0 million gallons and is located south of 1-694 along Red Fox <br />Road. The other storage tank has a capacity of 0.5 million gallons and is <br />located north ofI-694 along Femwood Avenue. <br /> <br />3. Water Trunk and Subtrunk Distribution Mains <br />A network of pipes and related appurtenances usually in the size range of <br />ten inch (10") to sixteen inch (16"). These pipes are designed to carry <br />large volumes of water and interconnect various point sources of water <br />supply and storage reservoirs. Appurtenances to these facilities would <br />include valves and fittings, but not fire hydrants. <br /> <br />4, Water Main Laterals <br />A network of water pipes and related appurtenances usually six inches (6") <br />or eight inches (8") in size that are installed with approximately eight feet <br />(8') of ground cover to retard freezing and are designed to serve those <br />buildings abutting a given street or easement. Lateral mains are "looped" <br />whercver possible to balance pressures and to provide water from at least <br />two (2) directions so that continuous water service is maintained for most <br />people during a water main break. Looping of lateral mains eliminates <br />dead end water mains that cause a variety of distribution and stagnation <br />problems. Appurtenances to these facilities would include valves, fittings <br />and fire hydrants. <br /> <br />5. Water Main Buildinl! Service <br />These pipes lead from laterals (or sometimes from trunk and subtrunk <br />mains) and serve individual buildings abutting thereon. The size of the <br />service usually ranges from three-quarter inch (3/4") to six-inch (6"), <br /> <br />2003 Assessment Policy Manual- Page 9 <br />
