Grass treatment swale
Web– A wet biofiltration swale is a variation of a basic biofiltration swale except, the longitudinal slope is slight and due to high ground water elevations the swale usually saturated. Continuous inflow swale – The runoff enters the swale continuously along the side slopes rather than directly at the head of the swale. Biofiltration Swale
