The City reduces sedimentation through its bi-annual street sweeping program. As part of the Farr Lake Study, the City is also investigating the installation of hydrodynamic separators at strategic catch basins. These hydrodynamic separators are flow-through systems that are installed within the stormsewer piping to remove sediment before it’s discharged into the ponds. Periodically, a vacuum truck would be used to suck out the sediment.
Residents can prevent sedimentation by:
1) Cleaning catchbasins to prevent leaves and sediment from washing into the stormsewer system (visit Adopt-A-Drain.org to learn more).
2) Properly managing their yard waste by either contracting for yard waste service or bringing it to the Anoka County Composting Facility.
3) Planting their yard, and especially shorelines, with native plants whose long roots can help filter out sediment
