Water Decontaminator Weir Catch Basin Filter

Weir Filter Installation

The Water Decontaminator Weir Catch Basin Filter can be installed in all types of storm drain catch basins. Here we show one being installed under a square grate. The WD Weir Catch Basin Filter is an environmental product that is placed under the catch basin grate to help remove trash, sediment, oil and contaminants from runoff. Oil and contaminants are captured in a disposable cartridge. The absorber cartridge uses recycled forest products, essentially fighting pollution with pollution. These units include the 5mm screened bypass to help remove floating debris.

Applications:

  • Urban run-off

  • Roadways

  • Parking lots

  • Industrial sites

  • Manufacturing

  • Maintenance areas

Helps clean parking lot run-off, catch basins, ponds, sumps and spills. Cleans storm run-off by screening sediment, debris and other solids into a sediment trap. Oils and chemicals are absorbed in a disposable cartridge
