Schematic showing pollutant load reductions for infiltrated and filtration in Bioretention basin (with an underdrain)
Example schematic showing how pollutant load reductions are calculated for a bioretention basin with an underdrain. In this case, total volume, TSS and phosphorus credits are 100 percent for infiltrated water, while credits for filtered water (water captured by the underdrain) are 60 percent for TSS and are dependent on the media for phosphorus.

Stormwater practices are designed and implemented to remove pollutants in stormwater runoff and/or to reduce the volume of runoff to surface receiving waters. Credit (stormwater credit) is a term used to quantify the reduction in pollutant loading or volume of runoff.
