Square Grate Water Decontaminator Catch Basin Filter
Square Grate Installation
The Water Decontaminator Catch Basin Filter - Trash Capture Unit (WD-TCU) can be installed in all types of storm drain catch basins. Here we show one being installed under a Square Grate. These can be 2-sided or 4-sided. The WD-TCU is a patented, 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 waste 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
The Water Decontaminator is engineered and patented for the treatment of stormwater run off. We design our filters to meet or exceed stormwater best management practices (BMP’s) and best available technology (BAT). These units are certified and included in the Capture System List of Trash Treatment Control Devices by the California State Water Resources Control Board.

The WD-TCU has several standard sizes, but can be custom fit to any existing catch basin. Please completely fill out the appropriate sizing guide below before ordering. Including pictures of the catch basin and bottom of the grate is also helpful.
Important Measurements
To insure a proper fit, all the items on the form should be filled in.
Cover style: There are several different styles of grates. Choose the style which is closest matches the drop ring or support ribs.
OD: Outside diameter of lip. This is the measurement of where the grate sits when installed.
OD-L: Outside length of lip
OD-W: Outside width of lip
ID: Inside diameter of opening. This is the smallest clear hole inside the catch basin. Take into account any rough concrete or restrictions.
ID-W: Inside width of opening. This is the smallest clear hole inside the catch basin. Take into account any rough concrete or restrictions.
ID-L: Inside length of opening. This is the smallest clear hole inside the catch basin. Take into account any rough concrete or restrictions.
GR-L: Grate Length
GR-W: Grate Width
A: Drop ring dimensions. Most grates are flat on the bottom, but if it does have a drop ring or other reinforcement bars on the bottom these need to be measured to insure clearance for the WD-TCU support frame.
B: Drop ring depth. Measure the part of the grate that extends below the lip it sits on. This is not the full thickness of the cover.
C: Depth of catch basin. Measure depth from the grate to the top of the liquid level. (Round only)
D: Depth of catch basin. Measure depth from the grate to the top of the liquid level. (Rectangular only)
Also note if there are any other issues that may need to be considered for fitment. For example access ladders, pipes or other restrictions.
