To optimize critical water retention and overall facility integrity, AUS performed annual inspections, maintenance and repairs for Cowlitz PUD’s power canals. Inspections and repairs in the canals include leak testing and repairing concrete lined Leak Monitoring Systems using specialty equipment and materials. AUS dive crews also inspect and test the earthen portions of the canal to confirm, assess and monitor any irregularities found in past surveys. With canal depths ranging from 20 to 65 feet, AUS provided a 5-person NITROX commercial diving crew with a full decompression chamber package to ensure safe and effective operations.
The primary objective of this work is to ensure the operational integrity of and safety of the facility while maintaining superior water management and compliance with regulatory standards.
