FAQ

If a wall or a tree falls on the barrier during a ood, what
solution do you propose?
The water barrier will simply wrap itself around the object that fell on it
and only a small amount of water will go over the barrier. All you have
to do is remove the fallen object, and the barrier will regain its original
position. The risk of tears from an object falling on the barrier is pretty
low. Should there be a hole or a tear, it can easily be repaired by
placing a piece of fabric inside the barrier. The fabric will adhere to the
inside wall simply from the pressure of the water entering the barrier.
What skills are required for installation?
Is training necessary?
No particular skills are required. However, basic training is
recommended. Installation is simple but we recommend reading
through the Training & Operators Manual
Can the Water-Gate system
open up fast enough
to stop waves?
The Water-Gate will open at the
same speed as that of any waves
coming in. This means that
regardless of the speed of the
oncoming water, the barrier will
open up like a parachute does in
the wind. However, if a wave has
white caps on top of it, the surplus
of water will go over the barrier and
will need to be pumped. To contain
all types of waves, the Water-Gates
can remain open. There are small
holes at the base and at the top of
the partitions in which stiff rods
can be inserted to keep the barrier
open at all times.
If the ood is a mudow, and
huge rocks get dragged down,
will the Water-Gate barrier
withstand the ood?
Yes, the water barrier can easily
withstand the pressure from a
mudow. Careful trials were carried out with success. As mentioned
in the Training & Operators Manual, the water barrier is at least three
times stronger than required. Given the fact that the density of thick
mud is approximately 1.65, the safety margin is excellent.
If the water barrier is left for several months or even several
years in a stream, will it stay in place during that period?
Yes, the barrier will stay in place provided the water level is not much
higher than the top of the barrier. Do not forget that the ow of a
stream never remains the same due to alternate periods of drought
and abundant rainfall. Also, in northern areas, the water barrier can be
disturbed by moving ice.
Will the barrier withstand parallel water ow?
Parallel water ow is not a problem. During testing, there was more
water owing than the barrier was intended to withstand, and the
current was swift. In this same trial with lots of parallel owing water,
we attempted to damage the barrier with wood fragments. Our testing
process was rigorous but did not result in any damage to the barrier.
How do I utilize the Watergate against a wall to prevent
water on that side from spilling over?
Use a board to hold it up against the wall if there is nothing to attach
the handles to on the wall.
What about leaks from the Water-Gate system?
No ood control system is 100% leak proof. Even if a system were
completely watertight, there would be leaks through the ground
from waste pipes, in addition to
rainwater falling on the part of
the ground that you are trying to
protect.
Water leaking through the barrier
generally ows under the barrier,
between the bottom of the barrier
and the ground underneath
it. Leaks occur because of the
unevenness of different surfaces.
However, the more the Water-
Gate barrier lls up with water,
the more watertight it becomes.
If the water barrier is laid down
on a regular asphalt surface, with
4in (10cm) of retained water, the
size of the leaks can be around
1Gal/minute/linear yard (4 liters/
minute/linear meter). However, if
the barrier retains 20in (50cm) of
water, only about 1/2Gal/minute/
linear yard (2 liters/minute/linear
meter) will leak from it.
Your emergency plan should
denitely include pumps to
remove any water leaking under
the ood control barrier as well as rain accumulating on the backside of
the Water-Gate. We recommend using gas powered water pumps that
do not depend on electrical power in case of power outages.
Do I need to use sandbags to hold it in place?
Sand bags and/or weights can be used to hold the Watergate in place
where the surface is uneven. The force and weight of the water owing
in the Water-Gate is what holds it in place.
