PART I WATER SUPPLY SYSTEM DESCRIPTION AND EVALUATION The City of Roseville Water Utility is a distribution only system, as all water is purchased through a wholesale contract with the City of St. Paul Board of Water Commissioners. Roseville's water utility supplies, via Roseville's system, water to the City of Arden Hills through an approved contract between the two communities and the City of St. Paul Board of Water Commissioners. The City's water utility became operational in 1962 with the constr'uction of feeder mains, a water pumping station, and a water tower. The utility grew as Roseville became nearly fully developed in the early 1980's. Today, the utility consists of a network of 190 miles of watermains, a 25,000+ GPM pumping station and 1.5-MG water tower. Since its inception, the Roseville water utility has purchased wholesale water from the City of St. Paul. The location of the St. Paul Water Treahnent Plant near Roseville's east boundary and its Dale Street reservoir which lies within Roseville contributed greatly to the decision to build a distribution only utility. The current contract allows for a continuous treated water supply up to a maximum 28 MGD to be available for Roseville and Arden Hills consumption. Current maximum daily consumption is far below that level. The current contract expires in the year 2004. Many of the sections in PART I of this plan that refer to the water source are referring to the St. Paul Water Utility water conservation and emergency response plan. Sections relating to consumption and storage capacities are outlined. A water distribution system map is attached in the pocket at the end of this plan. SECTION A. Analysis afWater Demand Historic water use is summarized in Table I-I. As shown, Roseville's population has decreased slightly over this period although the number of service connections has increased steadily. This period also indicates a steady increase in overall consumption as well as overall per capita consumption. Overall per capita daily consumption was 108.013 gallons in 1984, increasing to 139.443 in 1994. Most of the increase over this period can be attributed to commercial/ industrial use. Redevelopment of former truck terminals into light manufacturing and commercial industries has been a major factor in water use. Actual per capita residential use for 1995 was 83.10 gallons per day. This figure falls within range of other metropolitan area consumption rates. Page 3 of 22
