Hanson <br />MEMORANDUM <br />TO: Mayor Blesener & Members of City Council <br />FROM: Bill Dircks, Public Works Superintendent <br />DATE: February 6, 2008 <br />RE: On -Site Sanitation Dump Site <br />On -Site Sanitation has a Disposal Site Use Permit issued by the City of Little Canada and <br />the Metropolitan Council. It was issued in February 2005 and expires May 31, 2008. <br />(The initial permit was issued February 27, 1996 and has been renewed several times) <br />The permit allows On -Site Sanitation to dump the sewage it collects from its portable <br />toilets into a station at its Woodlyn location. The sewage then enters our system and <br />flows downstream in a twelve -inch main to a Metropolitan Council interceptor that runs <br />along Gervais Creek behind the Province Apartments. The permit was initially approved <br />in an attempt to work with and accommodate a local business. <br />As you are aware, the City has had problems with our sewer system in the area of On -Site <br />Sanitation in the past. The most recent case was a blockage that occurred in September <br />2005 that resulted in a claim that was eventually settled by the League of Minnesota <br />Cities Insurance Trust, but cost the City a significant sum of money. In the past, City <br />maintenance personnel have recovered objects in our system that have likely emanated <br />from On -Site Sanitation. We have also had additional partial and full blockages along <br />stretches of the sewer line downstream of On -Site. Lastly, there have been complaints <br />from neighboring businesses and residents about the smell that is created by the trucks <br />dumping their loads at the station. <br />On -Site Sanitation has made attempts to rectify the situation by building a new dumpsite <br />with a grate system to catch large objects before they enter the system. This system was <br />in place before the most recent backup so it obviously did not function as it was supposed <br />to. Mr. Dave Holm of On -Site Sanitation has been working with a pump manufacturer to <br />come up with a grinder -style pump that would break everything down prior to its entry <br />into the system. Staff is not sure that this would be a guaranteed solution, either. <br />Information on the proposed grinder pump has been. included with this memo. <br />2 <br />
