Settling devices rely primarily on sedimentation, in which coarse sediments and debris sink or fall out of the collected stormwater. Some settling devices also provide secondary screening to improve the capture of floatables and sediment. Stormwater management processes not provided in settling devices include volume reduction, peak flow reduction (minimal), infiltration (typically very minimal), filtration, sorption and biological treatment.
