A stormwater filtering practice (FP) treats stormwater runoff by passing it through an engineered filter media consisting of either sand, gravel, organic matter, and/ or a proprietary manufactured product, collecting it in an underdrain, and then discharging the effluent to a stormwater conveyance system. FPs are stormwater treatment practices that are often obtained from the marketplace due to unique proprietary technologies (see figure 1).
