Federal funding to expand wastewater treatment and sewer capacity
The City of Guelph will receive more than $33.4 million in federal funding to build a new tertiary wastewater treatment facility and upgrade trunk sewers, city officials and federal representatives announced in August. The investment is intended to increase treatment capacity, replace chlorine disinfection with ultraviolet technology and help accommodate thousands of new homes as the region grows.
Construction on the Water Resource Recovery Centre improvements is slated to begin in early September, with the overall project scheduled for completion by fall 2030. The federal contribution comes through the Build Communities Strong Fund and represents roughly 40 per cent of the project’s eligible costs, which are estimated at $83.7 million.
What the project includes
- Construction of a new tertiary treatment facility at the City’s Water Resource Recovery Centre.
- Upgrades to the Waterloo Avenue trunk sewer from Silvercreek Parkway to the recovery centre, including the section across the Hanlon Parkway.
- Extensions of the sewer system from Silvercreek to Edinburgh Road and a connection to the Wellington Street Trunk Sewer via Roland Street.
- Replacement of the current chlorine-based disinfection process with ultraviolet (UV) light technology.
City officials say the upgrades are expected to increase wastewater treatment capacity by 24 per cent and strengthen the system’s resilience as Guelph’s population and housing supply expand.
“Reliable wastewater infrastructure is essential to supporting a growing community,”
said Tara Baker, the City of Guelph’s chief administrative officer.
Funding and local actors
The federal announcement on Aug. 11 was delivered by Guelph MP Dominique O’Rourke on behalf of Housing and Infrastructure Minister Gregor Robertson, alongside Mayor Cam Guthrie and city representatives. The funding covers a significant portion of eligible costs but leaves the remainder to be provided by other levels of government or municipal sources as the project progresses.

| Estimated total eligible project cost | $83.7 million |
| Federal contribution (Build Communities Strong Fund) | $33.4 million (approx. 40%) |
Local implications and context
For Guelph residents, the project touches on several immediate and long-term concerns. Upgrading treatment capacity and trunk sewers addresses pressure on aging infrastructure as the city adds housing and industrial activity. Replacing chlorination with UV disinfection removes the need for chlorination and de-chlorination steps while maintaining treatment standards — a change with environmental and operational implications.
Municipal planning documents and city leaders have repeatedly linked wastewater capacity to the pace and location of new housing. Increasing system capacity by nearly a quarter could unlock additional development opportunities in growth areas and support the city’s intensification and affordability objectives, but it will also require close coordination between engineering, planning and finance teams to align construction staging with service disruptions and neighbourhood impacts.
Construction work along major corridors such as Waterloo Avenue and sections across the Hanlon Parkway is likely to affect traffic patterns and utility access during the multi-year build. City staff have previously noted that trunk sewer upgrades tend to be complex, requiring night work, lane reductions and staged excavations to maintain service while replacing or enlarging pipes. Residents and businesses near work sites should expect communications from the city about scheduling and mitigation measures as projects advance.
Federal participation in the project reflects Ottawa’s broader effort to support municipal infrastructure upgrades tied to housing and climate resilience. For Guelph, the infusion of capital reduces the upfront burden on municipal coffers and strengthens the case for proceeding with a sizeable upgrade that city planners have described as necessary to support projected growth through the next decade.
Construction crews are expected to mobilize this autumn, with phased work to follow. City staff will provide further details on permits, traffic management and timelines as contractors are selected and site plans are finalised.
