Stormwater Treatment Train

A stormwater treatment train is a series of different treatment practices designed to improve runoff quality from streets, parking lots, and other urban areas before it reaches natural water bodies. It combines several methods—such as filters, vegetated swales, sediment basins, and infiltration systems—to remove pollutants like dirt, oil, chemicals, and trash. Each step targets specific contaminants, working together to reduce pollution and protect aquatic ecosystems. This layered approach ensures more effective water cleanup, mimicking natural processes and promoting healthier streams and lakes despite urban development.
