- Water Diversion for the Pacific Gas & Electric West Point Powerhouse
Sierra Nevada Mountains, CA (2003)

The West Point Powerhouse needed to divert water away from one of
their work areas. An 8' x 75' AquaDam® had already been purchased
and used by PG & E on another project, so the plan is to save some
money by reusing it here.
Since the installation site was inaccessible by truck, the AquaDam® had to be lowered in with a crane.
All of the large rocks should have been removed from the
path of the AquaDam®, but this was not possible due to environmental
concerns. They will no doubt cause considerable seepage
underneath the dam and the PG & E workers had to use pumps to deal
with the water seepage.
Since there was no bank available to start the AquaDam from, large rocks
were used to elevate the fill tube end. Not exactly ideal, but it did get the
A view of the fully inflated AquaDam®. As you can see, all of the rocks are
now covered by the AquaDam®, and it extends into the deep hole. The maximum
water depth here was almost 7' in the deep part of the hole!
