Water-Gate Toxic Spills

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 circulation of water, to maximize the effectiveness of the absorbent tubes. Compatible with most emergency response equipment, the barrier facilitates the parallel use of other containment dikes and oil skimmers in shallow water (which is normally impossible).

Types of use

Containment of pollutants

By its nature, the Water-Gate has the particularity of literally blocking a flow of water by creating a barrier. 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 of certain booms and certain surface skimmers, absorbent powder or tubes, activated carbon for organic solvents, and others, which, combined with the Water-Gate WT model, demonstrate a doubly superior efficiency. Since the barrier traps pollutants in a common area, all that’s left to do is install this equipment precisely upstream of the barrier to efficiently extract the pollutants.

Underflow Dam

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.
