Floating motor pump for charged waters
Flow rate 144 m3 / h

Pumping of seepage water

No mobile flood protection system is completely waterproof. The very surface on which the dam is laid is not 100% watertight.

It is imperative to combine the Water-Gate © flexible dams with pumping means.
As on a boat the principle is to collect the trailing water, at the low point downstream of the flexible dam and to reject them over the ridge.

The leakage rate depends on many factors:

  • Underground pipes
  • Type of soil
  • Obstacles on the ground
  • Retention height (hydrostatic pressure)
  • Quality of implementation
  • Pluviometry

We calculate a leakage rate with safety margin for each installation.
We recommend the use of self-priming pumps or low level residue pumps coupled with generators.
