Along with the upgrade to AMR, the City will be conducting sump pump inspections. City Code requires that discharge into the City’s sanitary sewer system must conform to the Metropolitan Council Environmental Services (MCES) Waste Discharge Rules. Unpolluted water, such as rain water, storm water, groundwater, and water collected from foundation drains, may not be discharged into the sanitary sewer system.
Cities have found that some sump pumps have been installed incorrectly; rather than discharging water outdoors, clear water goes into the sanitary sewer system. This adds unnecessary strain on the sanitary sewer system. To comply with MCES directives to reduce inflow and infiltration (I/I) the City of Roseville has implemented the sump pump inspection program.
The current inspection program is to determine whether homes have a sump pump or not. Completing sump pump inspections in residential homes will give the city preliminary information on how many homes have sump pumps, how many non-conforming connections there are, and whether this is a major contributing factor to the City’s I/I problem. Staff will use the data that are collected to develop further I/I reduction plans in the City and make recommendations to the City Council.
