The cast-iron forcemain was <br />constructed in 1961. <br />Financial Impact: Engineering proposals were sent to Bolton & Menk, Inc. and Bonestroo for preliminary <br />engineering services to prepare a feasibility report for City Project 09-3, Lift Station #7 and Cleveland Avenue <br />Forcemain Improvements. Bolton & Menk's proposal was significantly less expensive than Bonestroo ($1,900 <br />vs. $7,500). Bolton & Menk was selected for this report and is recommended for selection for final engineering <br />services. This project including engineering and contingencies is estimated to cost $300,000. As this project is <br />designed, a more refined cost estimate will be provided to the Council. <br />Explanation: The lift station and forcemain are approaching the end of their respective service lives. The <br />existing lift station is showing signs of severe deterioration and corrosion and requires immediate attention. The <br />proposed solution is to re -line the inside of the metal lift station with a polyurea coating. We have re -lined two <br />other lift stations and have found this method to be successful at preserving the inside of the lift station structure. <br />The pumps and controls for the lift station were updated in 1985.and should be able to last another 5-10 years. <br />The 6 -inch cast-iron forcemain was installed in 1961 and has been in uninterrupted service ever since. A <br />forcemain is a pipe that conveys wastewater under pressure from the discharge side of a pump to a point of <br />gravity flow. It is a severe concern that the forcemain will break (much like a water main break) and cause a very <br />messy back up at the lift station. This particular lift station is our busiest. It serves all of the properties south of <br />Stowe Avenue and the businesses along County Road D (Perkins, etc.). The plan is to install a new parallel <br />forcemain along side of the existing main, remove the old main from service, clean it, and put it back in service as <br />a backup should anything ever happen to the new main. <br />January 13, 2009 <br />Consultant Selection Approved By Council <br />March 10, 2009 <br />Council to approve Plans and Specs, Authorize Advertisement <br />April 14, 2009 <br />Award Project to lowest responsible bidder <br />May 1, 2009 <br />Notice to Proceed <br />June 15, 2009 <br />Project Complete <br />Costs and Funding: This project has been programmed in the sanitary sewer rates to be constructed in 2009 and <br />will be fa d from the Sanitary Sewer Improvement fund. <br />410,/I <br />Gra t M. yffels, P.E. <br />Director of Public Works <br />Attachment — Estimated Project Fee <br />
