In Water-Works: Water-Gate & Overflow Diverter Tunnel

Replaces Over-Pumping

The Water-Gate is a temporary barrier which is unique in the way that once rolled out, it self deploys. It can be used as a cofferdam for in-water works.

It uses the weight of the water to hold the water back. The water lifts the top of the barrier whilst at the same time weighing the base down, forming a seal. By utilising this unique self-opening method, it reduces the time, effort and number of people required to install it, making this a truly rapid water diversion barrier.

It is highly portable and takes up limited storage space. The system is highly effective in strength, stability, function, ease of deployment and storage when compared with other flood defence products on the market such as sandbags, water filled barriers, booms etc. It is very versatile and can be used on flat or uneven surfaces.

The system can be used in conjunction with an Overflow Diverter Tunnel to replace over-pumping for in-water works.

Overflow Diverter Tunnel

Traditionally, sandbags have been used in streams to create a dry working area. When the water flow is blocked by the dam, the water level rises, and a pump is required to ‘over-pump’ the water downstream, past the dam. With the Water-Gate, an overflow diverter tunnel can be used which replaces the need for over-pumping. The overflow pipe clips onto the top of the barrier allowing the water to be channelled downstream.

The overflow pipe has a max flow capacity of 90 litres per second (5400 litres per minute).

The kit consists of two main parts: the overflow diverter and the main tunnel.

Overflow Diverter Diagram

Overflow Diverter

The Overflow Diverter is made of incredibly tough and hardwearing polyethylene. The black portion is funnel shaped to siphon off and drain excess water behind the Water-Gate. The yellow sliding float inside the diverter is intended to stabilise it, and allow the water flow to be adjusted. It is recommended to weigh the diverter down with a couple of ballast bags on top of the diverter to maximise the flow and improve stability.

Dimensions: 38cm (h) x 61cm (w) x 1m (l) 14.5Kgs

Main Tunnel

The main tunnel connects to the overflow diverter and can be used to channel water downstream.

The main tunnel comes with rugged handles every 1.5m (5ft) for easier handling. The tunnel is 22.7m (75ft) long.

Complete Kit

The complete kit includes both the Overflow Diverter and Main Tunnel: Code DA1200. Diverter tunnel benefits include:

  • Reusable
  • Environmentally friendly
  • Quick to install
  • Durable
  • Easy to use

After 4 floods in 16 years, the Water-Gate Barrier was used in November and December 2012. The relief when it prevented what would have been a 5th and 6th flood was enormous. The best part is the piece of mind that follows.
