Stormwater management systems are advanced drainage systems that help collect and remove or convey rainfall and surface water runoff. Most commonly, these systems utilize stormwater control measures and remove water from impermeable surfaces including paved parking lots or roadways after heavy rainfalls. Their main purpose is to divert water away from infrastructure, homes and businesses to reduce or mitigate flooding, erosion and scouring. The location, available space and expected runoff amounts, help determine which stormwater management process best fits each project or application.
