30 results about "Rain garden" patented technology

Rain gardens, also called bioretention facilities, are one of a variety of practices designed to treat polluted stormwater runoff. Rain gardens are a designed depressed area in the landscape that store runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas. Rain gardens typically rely on plants and an engineered soil media to soak up stormwater while absorbing and filtering pollutants carried in urban runoff.
