Schematic showing an infiltration basin, which is one of several stormwater control practices designed to infiltrate stormwater runoff. Infiltration practices capture stormwater runoff and allow it to infiltrate into the underlying soil. Pollutant removal occurs through a variety of mechanisms, including adsorption, absorption, plant uptake, and degradation. Note that inflow into the practice has undergone pretreatment and that once the practice is filled, runoff bypasses the practice rather than entering it.
