Storm Grate Filtration Quality is what the Dandy Sack is all about. The incredibly strong open-top bag is specially designed to hang underneath a storm grate to expertly filter the thickest sediment-laden storm water. The suspended solids are allowed to settle out of the slowed flow and are conveniently captured by the Dandy Sack prior to entering the inlet, making the sturdy Dandy Sack a storm water must.
