Bioswales are vegetated channels, that receive storm water that flows of roadways or parking lots during rainy periods.
What Does A Bioswale Do?
The purpose for Biofiltration Swales is to filter storm water runoff from roadways and parking lots. These pollutants generally are oils and fuels that are leaked on the pavement by cars and trucks.Pollutants are filtered from the water as it flows through the vegetation and adsorbed into the soil. Pollutant removal capability of a biopswale are directly related to its size, slope, and type of vegetation. Bioswales are also effective at trapping litter and leaves.
