Annacis Island WWTP Secondary Clarifier Mechanism

The Annacis Island Wastewater Treatment Plant Secondary Clarifier Mechanism Replacement project included replacing the mechanisms for Secondary Clarifiers No. 3 and No. 5.

The work included providing safe access in the clarifier (confined space egress), refurbishing the existing bridge and walkway, removing and disposing of the existing mechanisms, installing new owner-supplied mechanisms, starting up and testing the new mechanisms along with all associated mechanical, structural, electrical, instrumentation and control components, all as per the contract plans and specifications.
