An above grate based inlet filter system for erosion and sediment control comprises a natural fiber filter mat configured to extend beyond the perimeter of the grate and a securing mechanism, such as magnets, configured to securing the filter mat around the perimeter of the grate. The system may include a filter berm secured in vicinity to the mat, and a rectangular array of magnets coupling the filter mat to the grate. The natural fiber filter mat may effectively be a coir fiber filter mat extending beyond the perimeter of the grate, wherein the coir fiber filter mat is formed of vertically aligned coir fibers. The optional filter berm may be effectively formed as triangular in cross section and formed of 100% reticulated polyether foam and formed to be at least 3″ in height.
An above grate based inlet filter system for erosion and sediment control comprising a natural fiber filter mat configured to extend beyond the perimeter of the grate, a securing mechanism configured to securing the filter mat around the perimeter of the grate, wherein the natural fiber filter mat is coir fiber and wherein the coir fiber filter mat is formed of vertically aligned coir fibers.
An above grate based inlet filter system for erosion and sediment control comprising a natural fiber filter mat configured to extend beyond the perimeter of the grate, a securing mechanism configured to securing the filter mat around the perimeter of the grate, wherein the mat includes a plurality of high flow holes through the mat and closed at a bottom surface thereof.
An above grate based inlet filter system for erosion and sediment control comprising a natural fiber filter mat configured to extend beyond the perimeter of the grate, a securing mechanism configured to securing the filter mat around the perimeter of the grate, wherein the mat includes at least one removable dewatering plug configured to allow for selective mat bypass during high water flow.
