This spill response equipment combines simplicity, robustness and reliability. It is used to block or dam streams, small rivers or ditches for spill response and also to create water supply from small watercourses. The barrier has been specifically designed with ports or release holes on the lower portion to work as an instant underflow dam. With this feature, the first responders can use the Water-Gate to dam a stream, block a spill and control the release of clean water flow downstream.
The Water-Gate is designed for rapid and easy installation. Maximum retention heights are 21, 28 and 39 inches (53 cm, 71 cm and 1 meter) and units length from 15 to 50 feet (4.6 to 15.2 meter). Being lightweight, it is easily carried by one or two people to remote location. All Water-Gate models conveniently and rapidly attach together with a Velcro system. This gives first responders the latitude to adapt to all types of locations.
Spill response incidents in shallow water present difficult response recovery conditions. With the Water-Gate, a water course of a few inches in depth is conveniently transformed into a deep and calm response zone. With the implementation of the Water-Gate, skimmers, sorbent booms and vacuum units can be used conveniently with increased operational and cost effectiveness.
The Water-Gate can also be used as an overflow dam for sinking pollutants without affecting its integrity. Our barrier adapts itself to all types of terrain and river beds following basic instructions. Because of its incredible flexibility, the antipollution dam fits snugly against the river banks and stream bed no matter what the terrain might be. No anchor or pump necessary.
When firefighters or other first responders use the dam for water supply out of small water courses, the overflow will not affect the installation and some release holes can be left open to provide a minimum of stream flow in the habitat.

The Water-Gate’s waterproof effectiveness and stability come from the vertical thrust putting pressure on the bottom of the gate.
Main characteristics of the WT Series:
A – Ultra-strong PVC coated Polyester fabric resistant to abrasion for stream installation.
B – Compact partitions leaving the bib free for pumping water and making a safe access to cross the stream.
C – Polypropylene handles to raise the extremities of the barrier in particular applications.
D – Anti-mining bib to avoid riverbed erosion if overtopping occurs.
E – Heavy duty polypropylene handles to facilitate handling.
F – Release holes
The barrier has 4 times more floor surface than the water being retained, thus 4 times more vertical thrust (or on the ground) than the horizontal thrust allowing proper adhesion. For the water to hold back the water on most surfaces such as asphalt and grass, a 2½ to 1 ratio is usually sufficient for a safe installation therefore, the Water-Gate’s 4 to 1 ratio is much safer and the risk of slipping is unlikely. The wider the barrier, the harder it is to make it slip, we can then conclude that this Water-Gate spill response equipment is 33% safer than required.
No need to pump water inside.
