The AquaDam® is first positioned well up the bank, and then tied off to a
conveniently located tree. Two workers stand behind the AquaDam® to build
internal head pressure as it fills. When the pressure becomes great enough,
they will take a careful step back, allowing the AquaDam® to unroll approximately
Two of the workers were equipped with full diving gear so that they could
easily remove any underwater rocks or debris.
This will prevent damage to the AquaDam® and will greatly reduce leakage.
Whenever enough head pressure builds inside the AquaDam®, the workers take
another step back.
In order to turn the AquaDam®, head pressure must be released, so the pumps are
turned off. The workers on the outside edge of the AquaDam® move back while the
worker on the inside (in red) holds his position, allowing the AquaDam® to bend
Once the turn is completed, the pumps can be started and the AquaDam®
is allowed to continue to unroll, while the workers continue to maintain
the inside head pressure.
