Baffled AquaDam Pressure Test

This open-ended baffled 3' high AquaDam® is about to undergo a field test to see how it reacts when the maximum water level is exceeded. The AquaDam® is started well up the bank to ensure that it will be able to reach its full height. The worker holds it back as it fills to maintain interior pressure.

As the AquaDam® fills, the pressure builds, and a second worker is needed. They stop the dam just before it cuts off the flow. This is important, because if the AquaDam® starts to build water pressure behind it before it is done filling then it could be pushed downstream. The baffle provides additional support.

Once the AquaDam® has plenty of pressure inside, the workers allow it to finish unrolling. A small 1' high AquaDam® is placed underneath the larger unit to improve the seal with the ground. Almost no water can seep underneath.

A view of the seam where the interior baffle is attached to the outside tube, splitting it into two sections. This seam is reinforced on larger AquaDams®. The space above the seam allows for a pipe to be inserted to create a strong tie-off point. Using a rope, this point can be tied back to a tree along the bank, allowing for more stability.
