Stantec has been selected to provide detailed design and provisional construction management services for the new South Niagara Wastewater Treatment Plant and outfall, as well as the new South Niagara Trunk Sewer, announced the Regional Municipality of Niagara, Ontario.
The new plant will be built in a previously undeveloped area. Once the deep trunk sewer conveys flows to it, the facility will accommodate growth and reduce the impacts of wet weather flows in the region, according to Stantec.
“This is an important and transformative effort that will develop the infrastructure for the Niagara region to grow,” said Mike Kocher, Stantec’s design manager on the new South Niagara Wastewater Treatment Plant. “Our local multi-discipline staff, along with our team of international experts, are excited to work alongside Niagara Region to deliver this project that will help provide sustainable and reliable service for the area.”
The new projects fall under the South Niagara Wastewater Treatment Solutions (SNWWTS) $400-million program designed to service growth and reduce risk of basement flooding and system overflows.

The new wastewater treatment plant, expected to be operational in 2029, is anticipated to have a rated capacity of 30 million litres per day.
In 2024, Niagara Region staff attributed acute toxicity exceedances to out-of-service equipment and clarifiers in need of an upgrade at the Niagara Falls Wastewater Treatment Plant, which was built more than 60 years ago.
As part of the design for the new wastewater treatment plant, the project team says it will evaluate the opportunity to pursue Envision verification, an environmental and social certification for sustainable infrastructure projects. In 2015, Stantec achieved the first Envision-verified project in Canada with the Grand Bend Area Wastewater Treatment Facility in Ontario on the shoreline of Lake Huron.
Stantec is also providing guidance for the South Niagara Hospital, one of the facilities that will contribute flows to the new wastewater treatment plant. Stantec’s buildings team is providing planning, design, and conformance services for the new greenfield hospital, which will consolidate services from three sites and make it easier for residents to access care.
