The objective was to dewater the worksite in order to visually inspect a 32" natural gas pipeline for maintenance purposes. The work site was a bank on the Bogue Chitto River. This river is famous for its summertime recreational activities.

This was the proposed cofferdam layout. The river flow was going to be diverted around the worksite. Water quality was the paramount reason for choosing the new Aquadam® cofferdam system instead of older methods using earthen fill dams.

Step 1 was the installation of a 7' x 50' Aquadam®. The river flow was shifted to the opposite side of the river channel. The first Aquadam® was used as a "spacer" and provided support for the second Aquadam®, which bent around it. This Aquadam® was installed using three ropes because the water exceeded 6'.
