Of Report Number 13-168 ON Agenda Section VI-15 the city that works for�� Council Meeting Date July 9,2013 REQUEST FOR COUNCIL CONSIDERATION ITEM DESCRIPTION: APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE FOR BIDS FOR CITY PROJECT 13-6, SE SEWER LINING. DEPARTMENT HEAD'S APPROVAL: Gt,ttj CITY MANAGER'S APPROVAL: f No comments to supplement this report Comments attached Recommendation: To approve the plans and specifications for City Project 13-6, SE Sewer Lining and authorize staff to advertise for bids. Legislative History: The 2013 Sanitary Sewer Capital Improvement Plan includes lining the sewer mains in the southeast area of New Brighton. On October 26, 2012, staff submitted a grant application to the Metropolitan Council for Publicly Owned Infrastructure Inflow/Infiltration specifically for this project. On November 20, 2012, the City was selected for the 2012 METC Grant Program and sent a Preliminary Minimum Allocation (PMA)notice that the City would receive a minimum of$99,331 from the grant. On December 11, 2012, the City Council authorized preparation of plans and specifications for City Project 13-6, SE Sewer Lining. On January 15, 2013 the Metropolitan Council provided the grant agreement, which included a funding maximum of $102,716. On February 26, 2013,the City of New Brighton entered into a grant agreement with the Metropolitan Council for the Municipal Publicly Owned Infrastructure Inflow/Infiltration Grant Program for City Project 13-6, SE Sewer Lining. Financial Impact: The total estimated project cost is $425,000. Explanation: The purpose of this item is to advance the project to the next step which is to publicly advertise for bids. Bids are tentatively scheduled to be opened on August 20, 2013, with construction to bid with an early and late schedule. The early schedule will have a completion date of December 31, 2013, and May 31, 2014 for the late schedule completion date. In 2006 and 2010, the City televised 11,630-feet of old clay tile sewer pipe located in the southeast (SE) portion of New Brighton. The sewers are generally located between Cleveland Avenue and New Brighton Road. When viewing the sewer tapes, we found numerous offset joints, sags in the pipe, and roots in the main and service lines. Also, infiltration was evident in the main lines, as there are joints in the clay pipe every 5 feet (for approximately 2,300 joints in the project corridor). We have this area on a cleaning program of once per year. Based on the limited access to these lines, it is difficult to clean and provide root saw treatments. The SE sewer system was installed in 1958,with 80% of the homes being built before 1971 (as shown in the year built drawing enclosed). To limit inflow/infiltration caused by aging pipes/extra services/tree roots, the City of New Brighton proposes installing a liner in 10,810-feet of 8-inch sewer pipe and 820-feet of 10-inch sewer pipe. Lining of the old system will essentially create like new construction quality to the old clay pipe. The lining will be continuous between manholes with no joints, eliminating infiltration of ground water and root intrusions. This will not only reduce maintenance of these pipes,but will eliminate infiltration and lessen the chances of sewer backups. Costs and Funding: The total cost of this project is proposed to be financed for from Fund 402, Capital Sanitary Sewer Fund. Any grant funding received will reduce the amount needed from Fund 402. /4 Grant M. Wyffels,P.E. Director of Public Works Attachments
