Operations and Maintenance: <br />• The monthly MPCA Discharge Monitoring Report was completed and submitted as <br />required. <br />• March 1St, Lee and Anthony with Ritter & Ritter Co. jetted and televised our sewer <br />main on West Lake Street. <br />• March 13th, while doing manhole checks, noticed that the manholes by Tower Square <br />were backing up. Jetted the lines and removed lots of sand and grease. Started adding <br />enzymes to help break up any additional grease. <br />• March 17th, pulled pump #2 at Main L.S. and removed debris. Lots of debris stuck in <br />the impeller. Wear ring almost gone. <br />• Also on the 17th, I pulled our grinder pump again at the Water Plant. The alarm light <br />came on because the pump quit working. Took it apart to see if there was anything <br />caught in the impeller, but it's fine. Not exactly sure what's wrong with it. Called <br />Northern Water Works and they shipped us another loaner pump. They will need to <br />service ours again. <br />• March 29th, Kent with NorthStar Pump serviced all five of our lift stations. We will <br />need to replace the impeller on pump #2 at the Main L.S. They will send us a quote on <br />all repairs. <br />Report Submitted By: Tina Nolden (Water/Wastewater Operator) <br />�-- Please call me if you have any questions /comments. <br />218 -568 -5604 or 218- 820 -2125 <br />
