Introduction and Recommendations Introduction This report reviews the expansion of Centerville' water system through the addition of a 500,000 gallon elevated water tower and trunk water mains. This tower is needed to adequately serve the City as it develops towards saturation and expands into the next decade. The tower is also needed to: · maintain an effective balance between supply and storage, · increase and provide reliable fire flow capabilities within the water distribution network, especially on the outer fringes of the City, · provide a stable hydraulic basis for the operation of the water system, and · maximize efficiency within the water distribution network with the adjacent water system in Lino Lakes. This report reviews the construction of a water tower on City owned property next to the City Public Works Facility on 20th Avenue. Three factors were involved in choosing the size and type of water tower to be constructed - cost, reliability, and system operation. These factors are reviewed in this report. The location of the existing storage site and proposed tower are shown on Figure 1. Construction of this water tower is consistent with recommendations from the 1997 Comprehensive Water Plan prepared by MSA Consulting Engineers. The 1997 Plan recommended a 400,000 gallon tower be constructed by the year 2000 to give the City a total storage of 500,000 gallons. This report verifies the planned system expansion and recommends that a 500,000 gallon tower be constructed with the high water level raised 6.5 feet to match the water level of the City of Lino Lakes water system, and recommends that the City's existing water tower be removed from the system. The report also looks briefly at the expansion of supply to meet the anticipated future maximum day demand. Water Tower Feasibility Report 5
