Drain Filters for Stormwater & Oil Spill Control

Storm Drain Filter for Oil, Silt & Sediment Control

When rain hits your site, it isn't just water moving into the storm drains. It’s oil, silt, heavy metals, and debris. Using Inflatable Pipe Plugs, Oil Absorbent Pads and Spill Containment Berms can significantly reduce contamination before it reaches drainage systems.

If these pollutants reach the municipal drainage system, you're looking at pollution board notices, stop-work orders, and compliance failures during audits.

Drain Filter Inserts

Our drain filter sits inside the basin like an insert that removes oil, sediment, and debris from runoff before water exits your site. Simple to install, built to last through multiple monsoon seasons.

Protect Your Site. Protect the Environment

Install drain filters before the next audit, not after the notice. The Enviroguard Drain Guard provides the peace of mind that comes with knowing your site is compliant, rain or shine.

What Is a Drain Filter Used For?

Drain filters also called catch basin filters are used to capture oil, sediment, debris, and pollutants before they enter stormwater drainage systems. They are widely used in construction sites, industrial facilities, parking areas, and warehouses to ensure environmental compliance and prevent contamination. For handling hazardous liquid spills, you can also use Chemical Spill Kits as an additional safety solution.

Why Choose Drain Filters?

  • Superior Oil & Sediment Capture: Geotextile construction traps hydrocarbons and suspended solids while letting clean water pass through.
  • Compliance Made Easy: Specifically designed to help you meet NPDES, 40 CFR 122.26, and TMDL requirements.
  • Built-In Flood Protection: Integrated bypass ports ensure that even during "100-year" rain events, water continues to flow, preventing dangerous street ponding.
  • No-Tool Installation: Simply lift the grate, lay the guard over the opening, and replace the grate. The weight of the steel secures it instantly.
  • Versatile Protection: Available in Standard, High-Capacity, and Heavy Metal models to target your site’s specific pollutants.

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

Drain covers are for emergency use — you place them over a drain during a spill to block contamination from entering. Drain filters are 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?
