Iona Island WWTP CEPT Upgrade

Project Overview

PCL constructed this new chemically enhanced primary treatment (CEPT) building, tied into the supervisory control and data acquisition system, and demolished the existing temporary CEPT system at Metro Vancouver’s Iona Island Wastewater Treatment Plant.

The new 3,200-square-foot building is a steel superstructure on concrete foundation walls, built immediately adjacent to the existing operational settlement tanks and primary clarifiers. The team also installed owner-supplied polymer holding tanks, along with all associated mechanical and electrical tie-ins, including 7.5 kilometers (4.7 mi.) of cable and 1,000 electrical terminations.

As quality control was a priority, PCL worked closely with Metro Vancouver, meeting biweekly to review testing and commissioning procedures, as well as creating a custom checklist to ensure client specifications for welding were met. At project completion, PCL presented the client with a lessons-learned summary to assist them in refining their internal process. According to the client, PCL’s systems and management practices provided one of the most effective commissioning services that plant had experienced.
