Water-Gate Toxic Spills

Water-Gate’s spill barriers are very effective in providing control, containment and removal of pollutants in a toxic spill situation.


The Water-Gate WT model is very effective as it provides control, containment and extraction of pollutants in a toxic spill situation. This innovative intervention system stands out from competing models, among other things, by its flexibility, cost, accessibility but above all, its portable and reusable nature. These barriers are perfectly suited for emergency interventions in aquatic environments such as rivers, ditches, branches of rivers, streams or others.

The Water-Gate barrier slows the flow of water to maximize the efficiency of the absorbent tubes. Compatible with most emergency response equipment, the water barrier facilitates the parallel use of other containment dikes and oil skimmers in shallow water (which is normally impossible).

Under flow

This spill barrier has release systems at the bottom that can be opened or closed at any time (even during use).

Compatible and adaptable

This barrier can be used alone as an anti-pollution barrier or in addition to other intervention equipment.

Practical and revolutionary

The Water-Gate WT model is extremely easy to use, can be installed on most surfaces and is suitable for all types of spills, whether major or minor.

How it works

Water-Gate, a flexible and self-deploying barrier.


Direct water into the barrier

  • Water first enters the folds inside the barrier.


  • The water pressure opens the barrier completely.

Coming into action

  • The barrier is provided with a float which allows the fabric to remain on the surface of the water without letting water pass. The top of the canvas floats to the rhythm of the waves without letting water pass.

Modelled to the terrain

  • The accumulated pressure of the water causes the barrier to stabilize and mould to the terrain.

Opening and closing release holes

  • The release holes allow the barrier to contain the hydrocarbons on the surface while the water continues its course below (underflow circulation). The opening and closing of these 11.5 cm (4.5”) holes also ensure control of the water level upstream where the pollutants float.

Types of use

By its nature, the Water-Gate barrier has the particularity of literally blocking a flow of water by creating a dam. The water is housed at the bottom of the barrier and it deploys and fills automatically as the water level increases. Therefore, it is the weight of the water that nails the barrier to the ground and stabilizes it. In the event of a toxic spill, the pollutants are contained inside the barrier and can be easily removed using different methods and accessories:

  • Extraction pump: Water and pollutants are extracted from the contaminated area to an empty container until complete decontamination of the infected area. This practice is ideal in situations where the contaminated site contains non-floating pollutants.
  • Absorbent material: very effective intervention equipment exists on the market in order to facilitate the extraction of dangerous materials included in water, this is the case for certain booms and certain surface skimmers, absorbent powder or tubes, coals, active ingredients for organic solvents and others, which, combined with the Water-Gate WT model, demonstrate doubly superior effectiveness. Since the barrier traps pollutants in common, all that remains is to install this equipment precisely upstream of the barrier to efficiently extract the pollutants.

The release holes have been added to the barrier to provide it with a function allowing the underflow of water while the pollutants float on the surface. Release holes can be closed and opened at any time.

Absorbent tubes can be installed along the barrier to absorb all the hazardous material while the clear water continues its underflow. Water circulation is neither affected nor interrupted. Once filled, the absorbent tubes can be easily replaced. It is possible to attach them directly to the barrier.
