Non-proprietary Settling Device - System that is installed in stormwater sewers and that utilizes a sump to settle out sediment and other solids while also providing protection to the outlet to contain floatables, oil and grit.Multiple chambers - A design consisting of several, separate structures (manholes, catch basins, tanks, chambers, etc.) intended to increase pollutant removal, treat higher flow rates, or both.Media filter - Filtration of stormwater through a variety of different filtering materials whose purpose is to remove pollution from runoff.Grit - Coarse sediments such as smaller, loose particles of sand and stone or other heavy solid materials that have specific gravities or setting velocities substantially greater than those of organic particles.Grass swale - A vegetated channel that conveys stormwater while allowing for settling of sediments and debris (Synonyms Vegetated waterway, grass channel, drainage ditch).(Synonyms sediment forebay, sediment pool, small sediment basin, impoundment, basin, storage structure, excavated pit, upfront settling basin). Forebay - An artificial pool or reservoir that slows/temporarily detains flow to allow sediments and other solids to settle out.BMP - Best Management Practice: one of many different structural or non–structural methods used to treat runoff, including such diverse measures as ponding, street sweeping, filtration through a rain garden and infiltration to a gravel trench.Baffle - A device used to restrain water flow.
