LARGE AQUADAMS® (6' – 16’ high)

Equipment List:
-At least two discharge pumps are required; using larger or more numerous pumps will inflate the AquaDam® faster; the fill tubes can be opened to accommodate any size discharge hose.
-One discharge and suction hose per pump; discharge hoses do not require fittings.
-A roll of duct tape for securing the fill tubes.
-For safety reasons, each laborer should have a utility knife.
-In moving water, restraining ropes need to be used to assist the installation; at the very least, each 100 foot AquaDam® that is installed requires 250 feet of ½ inch rope. A four rope setup is strongly recommended on the installation of AquaDams® 6' high or larger in fast-moving rivers and streams (please see the Eagle River Crossing under the Installation section of our web site).

Manpower (for installation in non-moving water):
Three to five laborers are needed to install the larger AquaDams® in non-moving water. Ropes are usually not needed to restrain the AquaDam® from unrolling during the installation process, but can be used to pull the AquaDam® around if water depths are too great for a laborer to stand. Non-moving water conditions require the fewest number of laborers.

Manpower (for installation in moving water):
Five to seven laborers are needed to install the larger AquaDams®; the exact number of laborers is related to the size and number of AquaDams® to be installed, terrain, water velocity, water depths, and time constraints. Table 2 better describes the manpower needs during a typical installation of AquaDams® 6' or more in height in moving water.

Table2:
Manpower requirements are based on a particular size of AquaDam® in moving water. The chart also provides the number of ropes commonly used with a specific size AquaDam®. Note that 4, 6, and 8 foot structures are commonly installed with the aid of ropes to prevent them from unrolling prematurely. Only in standing water would rope assisted installations not be used on larger size AquaDams®.
