Description

Temporary cofferdams / Water supply

Water-Gate WA-Series can be used to quickly create emergency water supply / reservoirs for firefighters or instant temporary cofferdams. It uses a simple yet effective design to instantaneously divert, block, or contain water courses, small and medium size streams or contain water from aquatic area. Made of exceptionally strong materials, WA-Series are extremely reliable and quick to deploy.

This series is very useful for emergency interventions, particularly in remote or hard-to-reach locations, where fire hydrants are not available.

Fully portable, lightweight and easy to carry.

 

All models are compatible

All Water-Gate models conveniently and rapidly attach together with a Velcro system giving first responders the latitude to adapt to locations of all types.

 

Turnkey solution  – Rapid response

Water-Gate barriers do not need to be filled with water or air, nor do they need to be anchored. The barrier will automatically deploy as the water level increases.

They do not need additional material for installation, no gas or electricity. No heavy machinery is required to transport, handle, install, or take down the barriers (models with a maximum height of 28″/71 cm).

For work in streams, the Water-Gate is used as a temporary cofferdam for culvert changes, bank restorations, bridge repairs, canal dredging or other applications requiring dewatering. A weir and a tunnel kit are available to channel or divert excess water downstream across the dewatered zone.

Note: It is recommended, for installation on concrete, to use the WL Serie.

 

Who benefits from this product?

Water-Gate WA barriers are internationally renowned for being reliable, durable, and easy to use. The versatile and innovative design of WA Series barriers makes them ideal for rural or wildland firefighters, emergency responders, oil companies, public works departments, environment specialists, ecologists, and agricultural and mining companies, among others.

  • Suited for emergency operations in creeks, rivers, or ditches
  • Replaces dry hydrants
  • Minimum manpower
  • Small storage requirement

Advantages

A quick and easy solution

This innovative, turnkey solution is ideal for performing emergency interventions in record time. WA Series barriers require no additional hardware to set up or remove, nor electricity or additional materials. What’s more, they do not need to be...

Emergency response water reservoirs

WA Series barriers are a simple and practical solution for fighting fires in rural or forested areas. Lightweight and quick to install, the barriers are easy to transport to remote and hard-to-access places.

Temporary cofferdams

WA Series barriers instantly create a dry and safe space when working in areas under water. They can be used as temporary cofferdams when replacing culverts, restoring riverbanks, repairing bridges, dredging channels, and building concrete sewers...

4 golden rules for a perfect installation

1- Never dig behing the barrier | 2- Use a pump to move excess water upstream of the barrier
3- Place weights in front of the barrier to reduce infiltration | 4- Make sure you do not forget any object below the barrier

Main features

water supply - watergate wa series

Main features of the WA-Series :

A – Polyestser fabric coated with super heavy-duty, abrasion-resistant PVC suitable for use in streams.

B – Compact partitions leaving the front flap free to stand or walk on for pumping water and crossing the stream more safely.

C – Metallic rings or polypropylene front straps to facilitate installation in some situations.

D – Anti-erosion flap to keep the bottom of the stream from eroding if the water flows over the barrier.

E – Heavy duty polypropylene back straps to facilitate handling.

 

flood protection solution - instant dam - water supply

Water holding back water

The Water‑Gate flood dam has four times more ground surface than the water being retained, thus four times more vertical thrust (across the ground) than the horizontal thrust for proper adhesion. For the water to hold back the water on most surfaces such as asphalt or grass, a 2½‑to‑1 ratio is usually sufficient for safe installation. The Water‑Gate™ flood dam’s 4‑to‑1 ratio is therefore much safer and the risk of slippage is unlikely. The wider the barrier, the lower the risk of slippage. The Water‑Gate™ flood dam is 33% safer than required.

 

Modular and self-rising water dam

  1. Water infiltrates and collects inside the barrier.
  2. The water pressure helps the barrier unfold completely.
  3. The integrated floater allows the top part of the dam to float and absorb the motion of incoming waves.
  4. The accumulated water pressure stabilizes the barrier and keeps it in place regardless of the terrain beneath.

No need to pump water inside.

 

Did you know? The spillway replaces a heavy-duty pump and can drain up to 90 liters per second (1440 US gallons per minute). Learn more here.

Determine the flood dam you need

1

ASSESS RISK

Determine the nature of the flood
Take note of the flood level of your locality

2

DEFINE THE TRACE

Define the potential protection perimeter
Identify the presence of obstacles (trees, walls, etc.)

3

CALCULATE HEIGHT

Identify the lowest point of the protection path

4

DETERMINE LENGTH

Allow extra length when resting on a wall
Take into account the footprint of the soil

5

SELECT MATERIAL

Complete the response plan with pumps, quick deployment box, additional ballast, special anchorage, etc.

Barriers coding explanation / Definition of terms

WL letters represent the product range, e.g.: WL for flood protection, WA for water supply/temporary cofferdam, WT for hazmat/oil spill containment.

The first two numbers (26) represent the height in inches.

The last two numbers (30) represent the length in feet.

So WL-2630 means: a WL Series barrier with 26 in height and 30 ft length.
