Description

Why using the Water-Gate™ Spill Dam

The Water-Gate™ Spill Dam is very effective since it enables to control, contain and collect toxic spill in emergency situations. Its flexibility, cost, accessibility and more importantly, its portability and reusability, help distinguish this innovative emergency response equipment from more traditional models.

It is perfectly suitable for emergency situations in aquatic areas such as ditches, rivers, streams, stretches of river and more.

This too slows the water, in order to maximize the efficiency of absorbent booms and allow for easy introduction of containment booms and oil skimmers in shallow water conditions (normally not possible).

Our spill dam is used by experts

Many emergency responders and environmental specialists consider the Water-Gate™ Spill Dam as first-rate response equipment.

The Water-Gate spill dam (WT-Series) is used among other by the WCSS (Western Canadian Spill Service) for training and referencing purposes.

First responders now have a tool to set up an underflow dan in less than 5 minutes.

No risk of contamination

No machinery, pipe, or sandbag is required to install the Water-Gate spill dam. Simply unroll the barrier upstream the intervention site and the rest is done. Its unique design eases hydrocarbon containment in no time, which enable to prevent the spread of hazardous material towards a domestic network.

Safe intervention zone

The Water-Gate spill dam confines and stops the spread of hazardous materials while creating a calm and deep zone to extract pollutants (floating or not).

Whether your emergency involves a run-off of harmful substances from a pipeline, fuel truck accident, train derailment, plane crash, loss of electrical transformer, oil spill, pipes damaged during excavation work or any other accidental or non-accidental hazmat spill, the Water-Gate spill dam is the solution you’re looking for.

  • Underflow damming
  • Equipped with release holes
  • Environmental compliance
  • Create the adequate response site
  • Suitable with most emergency response equipment

Advantages

Underflow dam

The Water-Gate™ Spill Dam is equipped with low release holes that can be opened or closed at any time, even when in use. The main function of the release holes is to allow the barrier to contain hydrocarbons on the surface while allowing water to...

Compatible and adaptable

This lightweight and flexible barrier can be used alone as an anti-pollution dam or as an add-on to other intervention equipment. Once the spill is contained, other accessories can be added, such as absorbent materials, sorbent booms, oil spill...

Practical and revolutionary

The Water-Gate™ WT spill system revolutionizes the traditional methods used until now. Very easy to use, this solution can be installed on most surfaces and is suitable for all types of spills, from minor to major. While the speed of installation...

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

Main features of the WT-Series:

A – Polyester 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.

G – Release hole (with clasp)

 

flood protection solution - instant dam

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.
  5. The release holes at the back of the barrier allow containing hydrocarbons on the surface while allowing water to flow underneath. The opening and closing of these holes also controls water levels upstream where the pollutants float. When opened, the diameter of each release hole is 4.5’’ (11.5 cm).

Contain and collect the spill - MegaSecur - Water-Gate

 

Due to the weight of the water pressure on the backdrop, the Water-Gate™ guarantees an excellent seal.

  • Chemical resistance guaranteed for 12 hours (see chart for details)
  • Mechanical resistance: abrasion and tear resistant fabric/safe stitches.
  • Thermal resistance: +122°F (+50°C) to -40°F (-40°C) without any damage.

No need to pump water or air inside, as you would need to do with a tube or boom system.

The accumulation of water pressure stabilizes and molds the dam to the underwater terrain.

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.
