Abstract
A storm water runoff and erosion control device includes a rigid frame covered by a layer of mesh material. The frame defines an interior space that is filled with filtration material. The device may be configured as a wattle having an elongated frame with a triangular cross-section. The wattle may be extended along the contour of a hill to reduce erosion, or it may be placed at the entrance to a drainage inlet to slow the velocity of, and filter sediment and contaminants from, water entering the inlet. Alternatively, the device may be a compact filter that is a cube, cylinder, sphere, or other suitable geometry. A plurality of these compact filters may be placed in the basin of a storm water drain, and piled sufficiently high to cover the outlet from the basin. Thus, all the water in the basin must pass through the compact filters before exiting.
