Drain Filters for Stormwater & Oil Spill Control

Drain filters also called catch basin filters or catch basin inserts, sit inside storm drains and capture oil, silt, sediment and debris from runoff before it enters the drainage system. They are used on construction sites, industrial facilities, parking areas and warehouses to reduce pollution and support stormwater compliance.

The filter is made from geotextile fabric that traps hydrocarbons and suspended solids while allowing water to pass through. Overflow ports help prevent flooding during heavy rain. Installation is simple — lift the grate, place the filter, and replace the grate. No tools are required. For complete site protection, catch basin filters work alongside inflatable pipe plugs, oil absorbent pads and spill containment berms.

Drain Filter Features

  • Oil & sediment capture — geotextile traps hydrocarbons and solids while water passes through.
  • Overflow protection — bypass ports help avoid ponding in heavy rain.
  • No-tool install — lift grate, place filter, replace grate
  • Options — standard, high-capacity and heavy-metal configurations.
  • Site runoff control — reduces oil, silt and debris entering storm drains; supports industrial stormwater and consent conditions
  • Compliance Made Easy: Designed to help you meet NPDES, 40 CFR 122.26, and TMDL requirements.

How do I choose between a drain filter and a drain cover?

Drain covers for emergency use — you place them over a drain during a spill to block contamination from entering. Drain filters for ongoing protection — they sit inside the basin permanently and filter oil, silt, and debris from every rain event. Most industrial sites need both: covers near chemical storage for spill emergencies, and filters in all outdoor storm drains for continuous stormwater compliance.

Does Enviroguard supply storm drain filters across India?

Yes. Enviroguard supplies drain filter inserts for standard and large catch basins. Available in standard sizes (48×36" and 60×60") with oil-only, sediment, and heavy metal configurations.
