It <br />currently serves nearly 9,800 customers. The system consists of approximately 55 miles of <br />watermain, including CIP, DIP, and PVC pipe ranging from 4-inch to 16-inch diameter. The <br />existing water system is divided into two pressure zones, north and south. The north zone is <br />supplied by a booster station, and each pressure zone has one elevated storage facility. <br />Water Sources and Treatment <br />The City of Arden Hills receives its water supply from the City of Roseville, which in turn <br />receives its supply from SPRWS. The SPRWS Water Supply Plan is included with this report by <br />reference. Water treatment is provided by SPRWS, and no further treatment is required by the <br />City of Arden Hills. <br />The City has three service connection points with the City of Roseville: <br />1. Cleveland Avenue and County Road D (12-inch) <br />2. Fairview Avenue and County Road D (16-inch to 12-inch) <br />3. Hamline Avenue North and Glenhill Road (16-inch) <br />In addition to the three service connection points with the City of Roseville, Arden Hills also has <br />three emergency interconnections: <br />1.

City of New Brighton – East of Cleveland Avenue on Stowe Avenue (8-inch) <br />Water Storage <br />Each pressure zone in the system has one elevated storage facility.
