COUNCIL MEET1NQ <br />NOV ft 1999. <br />REQUEST FOR COUNCIL ACTION <br />CITYOFORONO <br />DATE: November 8.19W <br />ITEM NO.: / (^? <br />Department Approval: <br />Name Gregory A. Gappa <br />Title Director of Public Services <br />Administrator Reviewed:Agenda Section: <br />Engineer's Report <br />Item Description: Sanitary Sewer Lift Stations West Femdale Road & TH 12 <br />An Engineer's Report has been completed for the replacement and rehabilitation of the West <br />Ferndale Road sewer system lift stations and construction of the TH 12 bypass lift station. The <br />completion of these projects under one construction contract is scheduled for next year. <br />West Ferndale Road System <br />This system consists of five grinder pump lift stations that were originally installed in 1981. We <br />have experienced emergency repairs, as these steel canister lift stations are severely rusted <br />because of aggressive soils and high water table conditions. There are also capacity problems in <br />the system caused by deposits in the forcemain. The forcemain will be cleaned as part of this <br />project. The four steel canister lift stations will be replaced with fiberglass or polyethylene lift <br />stations. The one larger concrete lift station will be rehabilitated with pump and control system <br />replacement. The sewer capital improvement budget contained $90,000 in 1999, and $90,000 in <br />2000 for this project. The estimated cost for rehabilitation of the entire system is $230,000. <br />Highway 12 Bypass Lift Station <br />This lift station is required to provide additional sewer capacity to serve the new Orono Middle <br />School and other development in this area. During peak flow conditions, this station will pump <br />excess flow into the Maple Plain interceptor sewer. This station will be located in the northeast <br />comer of the Washington Scientific Industries parking lot which will require an easement. We are <br />recommending that this lift station be included in one project along with the West Ferndale Road <br />lift stations. The proposed schedule is for bidding of this project this winter with construction <br />next spring. Project completion is scheduled for July 1st for the TH 12 bypass lift station, and <br />September 30th for the West Femdale Road lift stations. The estimated cost for completion of this <br />project is $135,III! <br />We are requesting Council authorization to complete puparation of plans and specifications and <br />bid advertising for this project. The bids will then be brought to the Council for awarding of the <br />contract for this project.
