The frame comes preinstalled on all catch basin units from the factory and the removable cover makes the unit easy to inspect and clean.

Concrete cut-out guides are cast into the sidewalls for easy connection to PolyDrain® channels on all four sides of the basin.

The removable basket allows easy inspection and cleaning of the installed filter module.  And, built-in overflow relief ensures that the system functions even in the event that a rain event exceeds the expected peak flow capacity.

Replaceable filter media units are inserted inside the removable basket.  A wide variety of filter modules are available to address different site-specific contaminants.

Convenient drilling guides for 6" (150mm) outlets on all four sides of the basin or other pipe sizes can be fitted to the catch basin as required.
