Two AquaDams® were connected together to make one continuous dam.
This dam consisted of 3 AquaDams® joined end to end using coupling
collars. The two fill tubes in the foreground extended up through
the coupling collars. They are always several feet longer so that
they rise above the height of the installed AquaDam®.
The cofferdams on both sides of the river have been installed,
completely isolating the work areas. The water flow is maintained
in the middle of the river. The AquaDam® installation was completed
in only 1 day.
