Overview:
Stream Diversion. 

The Aquadam® goes over the diversion culverts and across the stream to isolate the work area from incoming water. This area will be pumped dry to work on power house plunge pool.

 
Step 1:
Unload 4' by 100' long Aquadam® and float it through plunge pool to the installation site.
 
Step 2:
Diversion pipes have been
installed to the proper gradient. The water is pumped into the end of the Aquadam®, which unrolls over the end of the diversion pipes. Water pressure being formed inside the Aquadam® is created by the water being pumped into it.
   
     Workers keep Aquadam™ from unrolling prematurely.
