The first two AquaDams have arrived at the job site and are being unloaded.

Typically, an AquaDam is shipped rolled up (like a carpet roll) and wrapped in a protective covering. Each one comes with either ropes or straps around the protective wrap for lifting and moving.

The first location for one of the 8ft tall double closed end (DCE) AquaDams.

The first 8ft tall DCE AquaDam has been place at the starting bank, removed from the protective wrapping, and slightly unrolled.

The DCE AquaDam has been launched off the starting bank and unrolled enough length, so that the fill-tubes have been exposed. The fill-tubes of a DCE AquaDam are on top of the body of the unit. A rope has been tied to the bottom seam of the roll to the top seam of the unrolled length to prevent the roll from unrolling.

The closed end on the unrolled length has been tied off to anchors, to keep the AquaDam from moving while filling.

The first 8ft tall DCE AquaDam has begun to fill with the pond’s water. The ropes (the workers are holding) have been tied to the roll end of the AquaDam to assist with turns and positioning.

The first 8ft tall DCE AquaDam continues to fill and has almost reached the ending bank.

After reaching the ending bank, ropes were tied to the other closed end of the DCE AquaDam to keep the unit in place while it finishes filling.

The second 8ft tall DCE AquaDam has been launched from its starting bank, at the second cofferdam location.

The closed end on the unrolled length of the second DCE AquaDam has been tied off to anchors to keep the unit from moving while filling.

The second DCE AquaDam has begun filling.

The first 8ft tall DCE AquaDam has been filled and isolated the work area.

The second 8ft tall DCE AquaDam has begun the desired turn to make a horseshoe/”U” shape configuration.

The second DCE AquaDam continues to fill and has almost reached the ending bank.

The second AquaDam was not quite long enough, so a smaller SCE AquaDam was rolled out underneath from the ending bank.

The second 8ft tall DCE AquaDam and the smaller unit have been filled and the second work area has been isolated.

The fill-tubes of a DCE AquaDam should be tied up and secured after filling to keep the water inside.

The third AquaDam cofferdam system has arrived. This AquaDam cofferdam system is slightly different from the last two as it uses single closed end (SCE) AquaDams, which require a starting bank greater in height than the maximum height of the AquaDam along its given path.

The third location for the last AquaDam cofferdam system. The first 8ft tall DCE AquaDam installation is behind where the excavator is sitting.

The first 6ft tall SCE support AquaDam has been place at the starting bank, removed from the protective wrapping, and slightly unrolled. The fill-tubes of a SCE AquaDam stick out of the starting point (open end) and may not come with discharge hoses.

The support AquaDam has been launched and has begun filling.

The starting bank for the support AquaDam. The starting point (open end) has been tied back to anchors to keep the unit in place.

The support AquaDam has been tied back to anchor points for positioning it towards the desired path.

The first 8ft tall SCE AquaDam has been launched and is now filling.

Ropes are tied between the 8ft tall and support AquaDams to limit space between the two.

The 8ft tall SCE AquaDam continues to fill as worker keep it as close as they can to the support AquaDam.

During the installation, workers determined that the 8ft tall SCE AquaDam was not quite long enough to reach the ending bank, as intended.

A used 8ft tall AquaDam was laid out, filled with air, inspected, and repaired (on site) for the additional required length.

A worker who was inside the used 8ft tall AquaDam making repairs.

An empty AquaDam will float on water and can easily be pulled/pushed into a desired location.

The closed end of the repaired 8ft tall AquaDam has been placed underneath the remaining rolled-up length of the first 8ft tall SCE AquaDam and the starting point (open end) has been pulled up the ending bank.

The first 8ft tall SCE AquaDam is no full, we can see it was several feet short.

The second 6ft tall support AquaDam has been launched, before filling the last 8ft tall dam.

All four of the AquaDams for the third cofferdam system have been installed and the work area is being dewatered.

Sludge bubbled up from the floor of the pond.

Great job AquaDam!
