City Council approval requires a simple majority vote of the City Council present. DISCUSSION The Metropolitan Council is currently monitoring the flow of sanitary sewer from each city to determine the amount of Infiltration and Inflow (I & I) to the Met Council treatment plant. If the city exceeds the allowance set by the Met Council, the City will be surcharged a fee based on the amount flow above the allowed amount. This project will help prevent I & I from entering the sanitary sewer system. The 2012 Sanitary Sewer Rehabilitation Project will consist of raising the height of the castings in low areas to prevent clear water from entering the sanitary sewer system. The areas being addressed are east of the Chanhassen High School and north of Lake Susan (see attached map). Two of the manholes which will be raised are completely submerged. The other manholes which are being raised are submerged during the spring snow melt or large rain events. Staff feels that this area is a large contributor of I & I to the sanitary sewer system.

Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Paul Oehme 2012 Sanitary Sewer Rehabilitation (I /I) Project February 27, 2012 Page 2 An additional I & I project is also being considered. It would involve the installation of short liners and grouting of manholes and joints. The project location would be east of the Chanhassen High School and north of Lake Susan. The reason the projects were bid out separately is due to the work being completed by different contractors. In the past when we bid the projects together the unit prices were higher due to one contractor having to find a sub for half of the work. This project would also be eligible for partial funding from the Met Council grant. On February 17, 2012, quotes were received and opened. The quotes and engineer's opinion of cost are shown below: Timing of construction helped keep the costs down. The work will be completed in the month of March which is a slow time for contractors. The low bidder for this project was Minger Construction, Inc. This contractor has completed work in Chanhassen in the past and their work was acceptable. Funding for this project has been budgeted for in the 2012 CIP, Project SS -012, and will be paid for by the Sewer Utility fund. The amount budgeted for 2012 is $75,000. We are also expecting 50% of this project to be funded with a grant we received from the Met Council. Attachments: 1. 2012 Sanitary Sewer Rehabilitation Project Location Map 2. CIP Page SS -12 3.

The program also detects and eliminates points of ;ntry of ground water and surface water into the City sanitary sewer system. Projects have been identified from the 2006 Inflow and Infiltration teport. The projects were reviewed by Metropolitan Council and approved in lieu of surcharge fees. . I Justification I City staff has identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to the City for sewage disposal and increasing the load on the City's lift stations.

It is the City's belief that as new customers come on line those connection fees should help fund future infiltration problems. 89 2012 2013 2014 20 2016 Total 75,000 75,000 75,000 75,000 75,000 375,000 Total. 75,000 75,000 75,000 75,000 75,000 375,000 2012 2013 2014 2015 2016 Total 75,000 75,000 75,000 75,000 75,00 375,000 Shamla, Joe From: Mulcahy, Joe goe.mulcahy @metc.state.mn.us] Sent: Tuesday, March 01, 2011 1:41 PM To: Oehme, Paul Cc: Shamla, Joe Subject: Municipal I &I Grant Attachments: II_opt_out_Form.docx Mr. Oehme, The City of Chanhassen's final municipal I &I grant amount is $78,760.
