MOM S VIEW <br />City of Mounds View Staff Report <br />off— <br />Item No: 8E <br />Meeting Date: May 14, 2018 <br />Type of Business: CB <br />Administrator Review: <br />To: Honorable Mayor and City Council <br />From: Don Peterson, Director of Public Works <br />Item Title/Subject: Resolution 8955 Approving the purchase of a Grinder for the <br />Groveland Lift Station <br />Background/Discussion: <br />The Public Works Department is responsible for overseeing the operation of the sanitary <br />sewer system which includes over 44 miles of sanitary sewer lines and two Lift Stations. <br />The Groveland Lift Station is located at Ardan Avenue and Groveland Road and has a <br />grinder installed to handle larger debris that enters the sanitary sewer system. <br />On March 19, 2018, Public Works received a high level alarm for the Groveland Lift <br />Station; the grinder had failed. The motor and grinder were pulled and brought to Electric <br />Pump, the vendor who services the JWC In-line grinder. Upon completion of the <br />inspection of the motor and grinder, Electric Pump notified Staff that the motor and the <br />grinder would need to be replaced. A large amount of flushable wipes had clogged the <br />grinder causing the grinder to bind and in turn burned out the motor. <br />Staff met with representatives from Electric Pump and the Manufacturer of the JWC In- <br />line grinder. Two (2) different options were discussed. Option 1 is to replace the grinder <br />with an upgraded unit and install in the same location. Option 2 would be to upgrade the <br />grinder but move the location to the upstream manhole, just outside the lift station. <br />Staff received cost proposals: <br />Option 1 $12,441.65 <br />Option 2 $42,730.00 <br />Recommendation: <br />Staff recommends the purchase of (1) JWC model 3004T -1200 -DI -WI In-line grinder from <br />Electric pump of New Prague, MN for the Groveland Lift Station at a cost of $12,441.65, <br />not including freight. The purchase will be funded from the Waste Water Infrastructure <br />account, 730-4823-7050, which includes $18,000 for upgrades at the Bronson Lift Station. <br />Respectfully submitted, <br />Don Peterson <br />Public Works Director <br />
