Potlatch Intake Mods

Project Description

The irrigation pump station is located in slow moving and shallow water. The intakes were constantly plugging up with material and AAC worked closely with the Columbia Improvement District to alleviate this reoccurring issue. The project objective was to build a sheet pile cofferdam cell around the existing intake structure and install 4, 63” diameter HDPE new intake pipes with new stainless steel T-screens and airburst system. This allowed the intakes to be relocated in faster, deeper waters to avoid the intake plugs. The airburst system alleviates hard, extensive manual labor when cleaning the intake screens and allows the pump station to stay online during the cleaning process; this is especially valuable during the critical irrigation season to many farms in the area.
