Ultra-Oil & Debris Blocker®

Stop pollutants before they can reach stormwater outflow

The Ultra-Oil & Debris Blocker is a simple yet effective stormwater management product that installs in the outflow pipe of catch basins.

By forcing water to enter the pipe from the bottom of the Oil & Debris Blocker, floating trash and debris are kept on the water's surface while dirt and sediment sink to the bottom of the basin.  Only clean water passes through to the outflow.

Key Features:

  • Stormwater is forced to flow through the bottom of the unit — floating trash and hydrocarbons remain on the water’s surface and out of the outflow.
  • Installs quickly and easily in storm drain outflows.
  • Low-profile allows Vactor trucks to clean catch basin without removing the unit.
  • Dual component, all-polyethylene unit will not rust or corrode.
Compliance:
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.

Frequently Asked Questions

What is the Ultra-Oil & Debris Blocker made from?  Will it rust or corrode?
The Oil & Debris Blocker is an all-polyethylene unit and will not rust or corrode.

 

What am I supposed to do with the trash/debris/sand/pollutants that get trapped in the catch basin?
Typically, the catch basin would be cleaned out periodically by a vacuum truck.

 

Is the Ultra-Oil & Debris Blocker difficult to install?
The most challenging part of installing an Oil & Debris Blocker is usually getting into the catch basin.  Once inside, the unit can be installed without any tools as it is designed to be held in place by tension.  You can see more details in the installation instructions.

 

How do I know which size to order?
Please feel free to contact us and we'll help you figure it out.  It will be helpful to fill out the measurement worksheet beforehand.

 

Does the Oil & Debris Blocker restrict water flow?
Because of the product's design, the Oil & Debris Blocker will reduce the catch basin's flow rate by a small amount.  The maximum restriction is 10% but 2-3% is more typical.

 

What other product should I consider for this application?
The Ultra-Debris Screen is similar to the Oil & Debris Blocker but is designed specifically for trash, debris and larger items.  It will not prevent oils/hydrocarbons or sand and sediment from exiting the catch basin.  Check out the Path to the Perfect Product to see what other products might be a good option.
