Identify one or more locations for connection between the City of Minneapolis and Saint Anthony <br />distribution systems. Factors to consider: <br />a. Size / capacity of the main to which connection is to be made. <br />b. Length of required connecting main and other possible indicators of an economical connection. <br />2. Characterize the approximate static and residual pressures at the potential points of connection, assuming a <br />maximum steady flow of 3,000 GPM into the Saint Anthony distribution system. <br />3. Items not in the scope of this analysis include: <br />a. Research into utilities, geotechnical, or other conditions that may impact constructability or cost. <br />b. Consideration of siting for pumping station or pressure reducing valves or vaults. <br />c. Detailed condition assessment of existing water mains under consideration. <br />d. Detailed hydraulic analysis. <br />e. Cost estimates <br /> <br />Summary of Findings <br /> <br />The Saint Anthony Village water system is south of the Hilltop finished water reservoirs owned by the City <br />of Minneapolis. The portion of the Minneapolis Distribution System that abuts the Saint Anthony Village <br />water system is a boosted pressure zone, called Northeast High Service Area. It is assumed undesirable <br />from the City of Minneapolis standpoint to connect to mains within the Northeast High Service Area. <br />However, a major pipeline, Pipeline 16, is located near the border of Saint Anthony Village, an d is not part <br />of the Northeast High Service Area. Pipeline 16 is provided its pressure by the Hilltop reservoirs. <br />Minneapolis has a pumping capacity of over 40,000 GPM to maintain the levels at Hilltop, so the 3000 GPM <br />demand for Saint Anthony Village can be readily accommodated.
