Oil & Debris Blockers® for Capturing Pollutants

Oil and Debris Blockers are an easy way to keep debris, oil and other pollutants from leaving the drain. Constructed from a high resistance polyethylene, these filters are naturally resistant to rust, corrosion and various pollutants. Strong in design and in use, these filters are the perfect way to contain pollutants and help ensure cleaner water from your outflow. See more drain guard BMPs.

How it Works: Oil and Debris Blockers sit directly in catch basins, attaching to the outflow pipe. Boil and debris blockerlockers are designed to allow only water to leave through the outflow pipe by:

  • Blocking Floating Particles and Oil
  • Increasing Settling Times for Solids
