In this sediment basin, silt fencing has been installed to create baffles and increase flow path length to provide greater sediment removal efficiency. The perforated pipe outlet (left) has been encased in #57 stone to further slow the discharge rate, thereby increasing settling time. Note higher sediment accumulations in basin cells at right, versus those on the left. (Source: Tetra Tech)
