Stormwater infiltration

Schematic showing an infiltration trench, 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.
