Knapp’s Corner Drain Project
The Knapp’s Corner Drain is a stormwater retention facility designed to hold the runoff water from impervious areas, such as parking lots, and slowly infiltrate it into the ground. However, the retention basin has failed and no longer infiltrates sufficiently. This means the runoff is not being adequately filtered and becomes a hazard to the surrounding homes due to high chloride and sodium concentrations in the groundwater. Thanks to ARPA funding, the drain project will be upgraded to pump the storm water runoff into a secondary detention basin that has an outlet. The water will then slowly soak into the ground and contaminants will be filtered out through the soil before water is released into the Grand River. This project will reduce the risk of flooding, reduce the cost of maintenance and reduce negative environmental impacts.
