MGAC on the Move: City of Toronto, Highland Creek Treatment Plant


The building process is complex and comes with common—and not-so-common—challenges. Learn more about what we do as Project Managers in our bi-monthly video series, MGAC on the Move. For each episode, a different member of our team gives viewers a behind-the-scenes look at one of their current projects. Now let’s get moving!

The Highland Creek Treatment Plant is one of the four wastewater treatment facilities owned and operated by the City of Toronto under the responsibility of Toronto Water. The 54-hectare plant serves 450,000 residences with a capacity of 219,000 m³. Due to the age of the infrastructure, key process equipment and buildings in liquid process areas are in need of upgrades to bring the equipment to a state of good repair and to ensure the plant continues to operate in compliance with current codes, standards, and design guidelines.

In this month’s MGAC on the Move, Pamela Tremblay, a Senior Project Manager in our Toronto office, gives us a tour of the Highland Creek Treatment Plant as it undergoes major upgrades.


Hello, this is Pamela Tremblay. I'm a senior project manager here at MGAC. Today, I'm gonna give you a tour of Highland Creek Wastewater Treatment Plant. Let's get moving.

We rarely think about what happens when you flush the toilet. The Highland Creek Treatment Plant is one of the four wastewater treatment facilities owned and operated by the city of Toronto and service over 550,000 people. Due to the age of the infrastructure, Toronto Water identified the need to upgrade some of the key process equipment and building to bring everything up to code. The waste goes through the primary clarifier for an initial cleanup before moving to the aeration tank and to the secondary clarifier. This process is referred to as a train. The effluent gets disinfected before getting discharged in the Ontario Lake. The project includes upgrades to the clarifiers, the aeration tank, the blower buildings, and many other upgrades to ensure that the waste is discharged properly. MGAC is providing project control services to the client to help highlight potential delays and avoid disruptions.

Hope you enjoy seeing what's happening at Highland Creek. Follow us to see MGAC next move.
