St. Anthony 2040 Comprehensive Plan Chapter 8: Water Supply 145 CHAPTER 8: WATER SUPPLY EXECUTIVE SUMMARY Introduction The City of St. Anthony’s Comprehensive Water Supply Plan describes the City’s existing water distribution system and water demands, projects future water demands through the year 2040, and proposes infrastructure improvements to accommodate those demands. This Plan has been prepared according to the guidelines established by the Metropolitan Council and the Minnesota Department of Natural Resources (DNR). The Water Supply Plan immediately following this report follows the template provided by the DNR, while this Comprehensive Water Supply Plan expands upon the template and provides further information for City and Metropolitan Council planning. Existing System The City of St. Anthony’s water distribution system provides nearly 300 million gallons of water each year to about 2,330 service connections. The system draws groundwater from three wells and is treated at the water treatment plant in the center of the City and stored between one ground storage tank and one water tower. The City has a single pressure zone, apart from the neighborhood just south of St. Anthony High School where pressures are augmented by a booster station located inside the Advanced Oxidation Process (AOP) Water Treatment Plant. Population and Water Demand The population served by the City’s water system has stayed constant over the last ten years. However, total water demands and per capita demands have been steadily decreasing, especially in the last five years. Higher efficiency appliances, reduced irrigation, general attitudes toward conservation, rainfall, and climate likely all play a role in that trend.
