The Water Decontaminator Catch Basin Filter - Trash Capture Unit
The Water Decontaminator Catch Basin Filter - Trash Capture Unit (WD-TCU) is a catch basin insert designed to fit any existing storm drain system.
This device is a patented environmental product that is placed under a catch basin grate to help remove oil and contaminants from dirty water. Oil and contaminants are captured in a disposable cartridge.

The Water Decontaminator TCU
The Water Decontaminator Catch Basin Filter - Trash Capture Unit (WD-TCU) is a catch basin insert filter system that treats stormwater, keeping contaminants out of stormwater and runoff. This is a certified full capture device for treating contaminants and trash. See approval letter on the California Water Boards website under Inventive Resources: www.waterboards.ca.gov
Basic Problem
Runoff from streets and parking lots carries trash, leaves, sediment, oils and heavy metals into storm drains. These contaminants and debris clog the catch basins and storm drain pipes, and eventually pollute our rivers and streams.
In most cases, stormwater can be treated before it leaves the site. There are many options for this treatment. Most of these are large and expensive vaults and separation systems that require intensive maintenance regimens and large footprints.
Introducing The The Water Decontaminator Catch Basin Filter
The WD-TCU is a full capture filter system. Low water flow rates entering the catch basin flows through a large filter cartridge with multiple layers of filtration and low absorbent media. In the case of high flow rain events, water first flows through the stainless steel 5mm mesh screen and then overflows the housing, preventing flooding.
The customizable deep bed loading filter cartridge can be made to any size. This is highly effective in removing sediment, oils, and most other contaminants. See the individual product pages for more information on the catch basin insert filter, as well as our other filter systems.

Trash Capture Catch Basin Insert
The WD-TCU is the best available technology (BAT) for treating stormwater at the source. Dirty water entering through the catch basin grate is funneled into the filter housing. The water then flows through a proprietary mixture of wood pulp media, polypropylene and activated carbon. This mixture has been shown to remove common pollutants entering the stormwater system. These pollutants include total suspended solids (TSS), oil, grease, and heavy metals. The treated water then flows out of the TCU into the catch basin.
The filter cartridge is designed so that first flush storm event passes through a denser portion of the filter. The first flush typically contain a larger concentration of contaminants. Maximum filter efficiency is achieved for the standard WD-TCU 10x18A filter at 20 gpm. Flow rates above 20 gpm will flow through the trash capture screen while removing all particles smaller than 3/16" [5mm]. Flow rates above 260-780 gpm depending on model overflow the filter housing through a built in overflow, not compromising the designed flow rate of the catch basin. An extended rim edge on top of the strainer cylinder helps retain collected debris should the flow rate exceed the rated maximum.
Larger units with multiple filter cartridges can accommodate any load. Filters can be fitted with an optional collection tube for effluent stormwater sampling.
Filter Spec:
Our filters can be customized to meet the client's needs and can be built in a number of configurations.
Available Filter Media
-
Proprietary Compost Blend
Compost filter media is organic material that has undergone the composting process and has had the small particles removed through a screening process.
-
Proprietary wood pulp particulate
Particulate / Cellulose Based Sorbents. Control hydrocarbons (oil based liquids) while repelling water. Absorbs liquids within fibers, absorbs oily sheens, tramp oils and other oil based while repelling water.
100% organic, environmentally friendly and Green Cross certified. -
Polypropylene Oil-Only Sorbents
Fine fiber Polypropylene absorbs up to 12 times its weight in liquids. Absorbs fuel oil, gasoline, motor oil, grease, organic solvents, and other hydrocarbons.
-
Activated Carbon
Processed to make it extremely porous with a very large surface area available for adsorption. This adsorbs a broad range of chemicals and hydrocarbons. Washed to reduce fines.
-
Heavy Metal Media
This media is designed to remove low concentrations of metals.
-
Perlite
Expanded perlite can be used in removing the typical suspended solids found in storm water. It can trap particulates and adsorb materials such as suspended solids, petroleum hydrocarbons, and particulate bound phosphorus, nitrogen, and metals. This optional media needs to be specified.
-
Partially Carbonized Organics
This new filter media is plant based and completely organic. Uses include reducing bacteria, total suspended solids, nitrogen and heavy metals.
-
Metal removing sponge material
This is a high capacity sponge product that effectively reduces and removes zinc, copper, lead and other heavy metals commonly found in storm water. This optional media needs to be specified.
-
Zeolite
This is a highly porous rock that effectively reduces and removes zinc, copper, lead and other heavy metals commonly found in storm water.
-
Phosphorus absorber
Specifically designed to remove phosphorus from stormwater.
Rainstorms often carry litter from streets into gutters and storm drains, which ultimately discharge into streams, creeks, rivers, and the ocean. Common pollutants include cigarette butts, paper waste, fast food containers, plastic bags, cans and bottles, used diapers, construction debris, industrial plastic pellets, old tires, and even discarded appliances. These materials, products of human activity, continue to degrade water quality across the United States.
Trash is a major pollutant with serious consequences for aquatic ecosystems, wildlife, and public health. However, this is a solvable problem. Reducing trash in waterways requires a coordinated effort among the public, regulatory agencies, community organizations, and permittees.
Just as trash comes in many forms, so do the solutions. Effective strategies include:
Routine street sweeping to remove debris before it enters storm drains
Public education campaigns to discourage littering and promote responsible disposal
Installation of trash-capturing devices on storm drains, such as the Water Decontaminator
Together, these actions can significantly reduce pollution and protect our shared water resources.
