This installation called for an AquaDam® that could control a depth of water in North Lake, which was approximately 8ft deep, in Estrella Mountain Ranch in Goodyear, Arizona. In this photo workers are placing the 10ft tall 21ft wide 200ft long single closed end (SCE) AquaDam. AquaDams are shipped rolled-up like a carpet roll on a wooden beam, wrapped in a protective covering, and have lifting ropes/straps.

The 10ft tall SCE AquaDam® being installed across the lake. Workers used the lake’s water to fill the AquaDam.

As the AquaDam® fills with water, the pressure from the water inside the fill-tubes pushes on the roll end causing it to unroll. The 10ft tall SCE AquaDam® has almost reached its ending bank. The rope around the beam in the center of the AquaDam® is helping to guide the dam into the proper location, where it will marry up to the bank square.

The 10ft tall SCE AquaDam® was still filling with water in this photo. When full it was approximately 10ft tall, 21ft wide, and 200ft long. An AquaDam® will only reach its full height at the lowest elevation along its given path.

An 8ft tall SCE AquaDam® was installed on the de-watering side (work area). This support AquaDam® also had the sides folded in when rolled up, so as it filled it unfolded to make contact with the main 10ft tall AquaDam. The pumps sucked water out of the lake and discharged it into the fill-tubes of the AquaDam. A SCE AquaDam® requires a starting bank to keep its starting point (open end) higher in elevation than the body of the AquaDam. The open end and fill-tubes of a SCE AquaDam® must stay elevated higher than the full height of the dam along its given path. Workers used ropes to secure the open end of the AquaDam® while it was filling.

The 8ft tall SCE support AquaDam® has almost completely unrolled and needs to continue filling.

Workers also installed a 6ft tall SCE AquaDam® behind the 8ft tall AquaDam® (which was supporting the main 10ft tall AquaDam). The work area was now ready to be de-watered.

A pump was set up to remove the water from the work area. Notice how the AquaDams abutted next to one another. The smaller units provide support to the larger ones that they are up against. All the fish that were trapped in the work area needed to be put back into the greater body of the lake. This was accomplished by a group of local children that were able to catch them with their hands and nets.

Workers now had a mostly de-watered work area. Notice the man walking towards the middle of the pond, next to the black suction hose attached to the pump.

This cofferdam needed to be replaced after a piece of equipment put a large hole into one of the AquaDams. The equipment operator was trying to stop seepage underneath the AquaDam® and accidentally swung the backhoe bucket into it. This created a domino effect and within minutes all three AquaDams moved out of position and drained. Workers returned later to install a larger set of AquaDams.

Back at North Lake in Goodyear Arizona for installation number two.

Here we can see the fountains of North Lake.

This set of AquaDams has been delivered on a flat bed trailer with a diesel pickup truck.

The first SCE AquaDam® has been placed into the lake. An AquaDam® is made of material less dense than water, allowing it to float in water and be transported to the desired location before being filled with water to create a barrier.

The initial SCE AquaDam® installed is secured with an anchor at its open end to prevent movement as workers fill the dam with water. To ensure proper installation and functionality of a SCE AquaDam, it is essential to have a starting bank that maintains a higher elevation than the body of the AquaDam. The open end and fill-tubes of the SCE AquaDam® must remain elevated above the full height of the dam along its designated path. It is important to note that an AquaDam® will only reach its maximum height at the lowest elevation point along its designated path.

To enhance the stability of the open end of an AquaDam, you can secure the outer sleeve material around a rock and tie it securely with a rope. This method will help prevent any shifting or movement of the AquaDam, ensuring its effectiveness in containing water.

As the AquaDam® is filled with water, the pressure from the water inside the fill-tubes pushes against the roll end, causing it to gradually unroll.

Workers secured a rope to an anchor on shore and attached it to the AquaDam® to assist in positioning the dam as it filled with water.

The first SCE AquaDam® continues to fill. In this photo we can see the fill-tubes laid out on the bank, protruding from the open end.

After an AquaDam® has head above the surrounding water level, workers can utilize the body of the dam to walk on and secure ropes to. This allows for efficient and safe installation of the AquaDam.

The worker here in this photo, wrapped a rope around the width of the dam to use as an anchor point.

A rope has been tied to the roll end and the other end will be thrown to shore for workers to pull on. The AquaDam® must meet its ending bank square.
The first SCE AquaDam® has almost unrolled to its ending bank.
The worker has hopped off the AquaDam® and onto the ending bank.
Abutting to native soil will create the best seal, but an AquaDam® can adapt to various types of surfaces.

The first SCE AquaDam® has made it to its ending bank and will now need to finish filling.
This AquaDam® has been installed in a line configuration, from bank to bank.
A worker is pulling the next AquaDam® towards its starting bank. This AquaDam® is shorter in height and will be used to support the larger one that is already installed.
Workers are installing the second SCE AquaDam. The outer fill-tube (right) was mostly filled first so that as the inner fill-tube would fill it would push up against the larger dam creating a tighter seal.
The second SCE AquaDam® continues to fill and workers prepare to install the next dam.
As the support AquaDam® fills, the distance between the two should decrease. The closer the dams are placed, the more effective the support will be. It's crucial to ensure there is no space for water to get trapped between them.
AquaDams are constructed using lightweight and flexible materials, allowing them to float when empty in deep enough water. The black material seen at the end of this AquaDam® is a connection collar.
This AquaDam® requires additional water for workers to utilize its connection collar effectively. The connection collar enables the cofferdam to extend its length by connecting one AquaDam® to another.
The second SCE AquaDam® continues to fill and the gap between the two continues to disappear.
The second SCE AquaDam® is almost full and ready for the next dam to be connected in its collar.
Workers have made the connection and have already begun filling the next dam. The fill-tubes of the third SCE AquaDam® have been pulled through holes in the collar and blue discharge hoses where inserted into them. The open end of the third AquaDam® was bloused out on top of the closed end of the second dam, inside the collar. The closed end of the second SCE AquaDam® is acting as the starting bank for the third AquaDam.
The collar is stretched out around the third AquaDam® to help make a snug fit.
A worker stays with the newly connected dam to ensure the collar is stretched out with no wrinkles. When connected properly, the collar prevents the open end and fill-tubes from shifting around.
As the third SCE AquaDam® is being filled with water, workers are using ropes to pull the support dam closer to the larger one.
Just like the second SCE AquaDam, the outer fill-tube was filled first.
The third SCE AquaDam® continues to fill.
The fill-tube on left side is now filling and unfolding towards the larger dam.
The third SCE AquaDam® is almost completely unrolled.
The third SCE AquaDam® is now full and its fill-tubes have been tied up to prevent them from draining any water. The second SCE AquaDam® was replaced with a taller dam and its connection collar appears to be white.
A close up of the fill-tubes of the third SCE AquaDam. To ensure the water stays inside, make sure the fill-tubes are positioned higher than the AquaDam® itself.
Another SCE AquaDam® was installed at the starting bank end of the first SCE AquaDam® as a support on that side.
A small gap was intentionally left between the two closed ends to allow any water trapped between the dams to drain out during the de-watering process.
Workers can now begin de-watering the work area.
As the work area is dewatered, the dams squeeze together to create a tighter seal.
