King County - Wastewater Treatment Division - Carkeek/Richmond/Alki Outfall Repair - Alki
We provided all project management, diving services and topside support for this location as part of an overall three-outfall repair project. Work done at Alki involved the installation of five new anode sleds. Tabs were welded to the existing outfall, and leads connected the new anode sleds to the outfall. At the conclusion of the installation, measurements were taken at 22 locations along the outfall to verify the increased cathodic protection.
Welding was performed in 100 feet of water, as was setting of the five anode sleds.
