- Pipeline Canal Crossing
Parker, AZ (2000)

Original plans called for directional drilling underneath four separate
locations on the same canal system. The directional drilling failed, and
an "open-cut trench" method had to be used. The AquaDams® were required
to accomplish dewatering of this section of the canal.
The 8' AquaDam® is holding back quite a lot of water (depth is 6'),
so it is reinforced with a 4' AquaDam® behind it.
You can also see another set of AquaDams® underneath the bridge. Notice
the bank slope on the dewatered hole. The AquaDam® had to go
over similar material during its installation. This allowed considerable
leakage underneath the AquaDam® to occur.
