County Road 50 Iron Enhanced Sand Filter
This project proposes to treat 50% of the subwatershed runoff with an offline, multi-cell iron enhanced sand filtration (IESF) treatment system. The headwaters of Washington Judicial Ditch 6 (WJD-6) is dominated by wetlands and contributes nearly half of the total phosphorus load in the WJD-6 system, most of which is dissolved and difficult to remove with traditional best management practices (BMPs). This IESF will reduce watershed phosphorus loads to Forest Lake by 85 lb/yr.
The CLFLWD received a $747,400 Clean Water Fund (CWF) grant from the Board of Water and Soil Resources (BWSR) for this project. View the latest CWF grant report here.
