Post, Interim City Administrator <br /> <br />Dwayne Stafford, Public Works Director % <br /> <br />1999/2000 Sanitary Sewer Rehabilitation Project <br /> <br />FROM: <br /> <br />SUBJECT: <br /> <br />Backeround <br />As a result of televising a portion ofthe City's sanitary sewer system each year, staff has <br />identified segments of the City's sewer system needing major rehabilitation. A sizable amount <br />of pipe was rehabilitated in 1998/99. <br /> <br />The next area prioritized for rehabilitation is the twelve-inch (12") clay main sewer line that runs <br />east to west from Old Highway 10, approximately 2,300' west behind the new Lake Valentine <br />townhomes. This line has numerous cracked pipes, leaking joints, and root problems and is <br />located in a wet, marshy area. This is the main sewer line serving the Mounds View High <br />School area, as well as a portion of the Chatham neighborhood. <br /> <br />The City's Consulting Engineer, Greg Brown, and City staff have agreed that lining this segment <br />would be most feasible, as excavating and replacing the line would necessitate the removal of a <br />one-hundred foot (100') swath of trees and the building of a temporary access road. Currently, <br />the City has a twenty-foot (20') easement for sewer line maintenance. <br /> <br />A lateral line is connected to the above-referenced main line, which services approximately half <br />the Chatham area. This line crosses a creek and County Road E-2 and connects to the above line <br />just west of the Lake Valentine townhomes. One segment of the Chatham connection has an <br />estimated one-foot (I ') dip in the line that has resulted in continuous maintenance problems for <br />the Public Works Department. <br /> <br />Costs <br />The City Council authorized staff to combine the two (2) referenccd priorities into one project, <br />and use monies budgeted for 1999, and monies proposed for the year 2000 for the project. These <br />monies amount to $250,000 total, including monies proposed for televising, and would come <br />from the City's Sewer Fund. <br /> <br />Bids <br />Attached is a memorandum from Mr. Brown regarding bids received for the rehabilitation of the <br />two areas, and for televising a third section of the total eight (8) sections of the City's sanitary <br />sewer system. <br />
