The WHALE Oil and Debris Blocker is the perfect tool if you are looking for a system that prevents oil and debris from mixing in with clean water. With the WHALE, you can stop the pollutants before they reach the stormwater outflow. The system works by forcing stormwater to flow through the bottom of the unit; so, trash and hydrocarbons remain on the water's surface and away from the outflow.

  • Low-profile allows vactor trucks to clean catch basin without removing the unit.
  • Dual component, all-polyethylene unit will not rust or corrode.
