This lift station renovation has been discussed with Paul Patzer of Centerville Public <br />Works. Two possible options for this renovation were investigated. <br /> <br />Ootion No.1 Replace existing pumps with a non-clog submersible pump, new controls, and a <br />valve vault. Total Construction Cost = $73,100 <br /> <br />Ootion NO.2 Replace existing pumps with submersible grinder pumps and controls. This style <br />of pump grinds up the solids and requires smaller discharge pipes, which allows <br />all valves to be installed in the existing wet well. The valve vault installation is <br />not required with this option. Total Construction Cost = $50,000 <br /> <br />Following discussions with Paul, Option No.2 was selected as the preferred renovation plan. <br />The construction cost is significantly lower because a large valve vault structure would require <br />expensi ve dewatering to install. <br /> <br />We therefore request that the City Council approve the Lift Station No. I Plans and Specs and <br />order Advertisement for Bids <br /> <br />Please call me at (651) 604-4848, or Tom Peterson at 65 [ (604) 4868 if YOll have any questions. <br /> <br />Very truly yours, <br /> <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INe. <br /> <br />Of~ <br /> <br />Daryl Kirschenman, P.E. <br /> <br />Enclosures <br /> <br />2335 West Highway 36 " St. Paul, MN 55113" 651-636-4600' Fax: 651-636-1311 <br />
