Adopt Resolution # 14-09-193 Authorizing The Application For Metropolitan Council Environmental Services (MCES) 2014 Municipal Inflow & Infiltration (I&I) Grant
 

The purpose of this case is to authorize staff to apply to the Metropolitan Council for  matching grant funding to help mitigate infiltration/inflow in our sanitary sewer system.   The Metropolitan Council  appointed a task force that met in 2003/2004 to address the impacts of excess infiltration/inflow (I/I) on the regional sanitary sewer system by developing recommendations for an I/I reduction program.

Inflow and infiltration is that component of sanitary sewage flow that originates from clear water connections, e.g., sump pumps and foundation drains (i.e., inflow), and storm water entering manholes and groundwater entering through pipe joints and cracks (i.e., infiltration). It is water that would normally not require any type of treatment. However, once it is co-mingles with sanitary wastewater it cannot be separated, and must be treated along with the sanitary wastewater.

The I/I Task Force estimated that the cost to store, convey, and treat excess I/I was in the $900 million range while the cost for source removal was in the $150 million range. The Task Force recommended a program to mitigate excess I/I rather than increase system capacity.

The sanitary sewer system for Ramsey consists of 63 miles of sewer main, 7 lift stations and 1500 plus manholes.  Currently our utility department cleans 1/3 of our system and televises 1/10 of the system annually.  We are also currently in the process of inspecting all sanitary sewer manholes and cataloging their condition.   What the manhole  inspections are finding are cases of I&I around the manhole joint seals, in the adjustment rings near the road surface and the areas where the sewer main enters the manhole.  These  are the types of maintenance issues that the Met Council would like to see  eliminated.   This particular grant allows cities to estimate project costs, before the projects are bid and then reconcile after the project completion.  Cities have until September 30, 2016 to submit pay claims for completed projects.  The maximum amount that the city can submit for I&I repairs is $25,000.00.  It is proposed that Ramsey make a grant request in the amount of $25,000.

The city's match would come from Enterprise Fund 9602 (sewer utility)
