Sediment, trash, debris, and organic materials found in stormwater runoff can clog and significantly affect the functionality of structural stormwater best management practices (BMPs). Reducing these burdens prior to entering structural stormwater BMP(s) will preserve their long-term functionality, particularly for filtration and infiltration BMPs. Pretreatment reduces maintenance and prolongs the lifespan of structural stormwater BMPs by removing trash, debris, organic materials, coarse sediments, and associated pollutants prior to entering structural stormwater BMPs. Implementing pretreatment devices also improves aesthetics by capturing debris in focused or hidden areas.
Pretreatment practices serve an important role in the stormwater treatment network. They are installed immediately preceding one or more structural stormwater BMPs and are designed with consideration of the flow network and the downstream structural stormwater BMP characteristics. Pretreatment is highly recommended as an integral part of all post-construction structural stormwater BMPs and is required as part of Minnesota’s NPDES/SDS Construction Stormwater (CSW) General Permit for filtration/infiltration water quality BMPs (section III.D.1.d). Pretreatment practices are NOT stand-alone treatment practices and should only be installed in conjunction with a treatment practice immediately downstream.
This category provides links to photos of pretreatment practices.
