Stormwater Filtration

Stormwater filtration: catch contaminants before they reach waterways to stay in compliance.

Filtration can be a crucial part of an effective Stormwater Pollution Prevention Plan, and a good practice for protecting your drains from contaminants and keeping the water supply clean. There are a few ways to filter: Storm Drain Filters sit below the grate of your storm drain to catch pollutants; Drain Filter Socks wrap around the outside of your storm drains or sit in front of curb inlets to block pollutants and prevent ponding; and DeWatering Filters let water run through and hold onto oil and sediment during high-volume pumpouts. Outdoor filter berm pads contain leaks of oil and fuels from small equipment but let clean water run through. Combine storm drain products in a sequence to create a treatment train for maximum impact against pollutants with a Storm Drain Filtration Bundle.


An effective drain oil filter catches and collects contaminants like oil, hydrocarbons, sediment, silt, trash, debris, and heavy metals, while letting clean stormwater run through. We’ve hand-picked drain filtration products that can help you comply with EPA’s SPCC and Stormwater Regs – plus, incorporating any of these products into an SWPPP is just common sense.
