BOWMANVILLE, ONT. — Aecom has announced it has been selected by the Regional Municipality of Durham to provide engineering services for upgrades to the Port Darlington Water Pollution Control Plant (WPCP).

The plant serves 50,000 residents in Bowmanville. The updates are intended to upgrade the performance of the plant, boost environmental sustainability and reduce energy waste and overall operational costs, stated a release.

The four-year contract’s scope of work is comprised of two upgrade projects. The first will focus on replacing the existing Waste Gas Burner (WGB), which is at the end of its service life, with an enclosed flame WGB. The second project will involve upgrades to Plant 1 liquid treatment systems, the supervisory control and data acquisition (SCADA) software system, and other clean-up work around the plant.

Key project components include updating the Plant 1 primary and secondary clarifier mechanisms, upgrading the Plant 1 aeration tank aeration system, and full SCADA and PLC (programmable logic controller) programming. All SCADA and PLC programming, along with commissioning, will be completed by the AECOM team in-house.

Beverley Stinson, chief executive of AECOM’s global water business, stated, “Our  strategy centres around the role of infrastructure to deliver a better world, and we’re proud that this program presents an opportunity to protect Durham’s waterbodies and greatly enhance its environmental safety and sustainability.”

Similar retrofits and upgrades have included delivery of Los Angeles’s Joint Water Pollution Control Plant and New York City’s Wastewater Resiliency Program.
