REGION INVESTS $15.1 MILLION TOWARD WATER CAPACITY ISSUE
The Region of Waterloo is hurrying to install a $15.1 million temporary plug into a water capacity crisis that effectively hung a “Closed for Business” sign over one of Canada’s fastest-growing tech hubs.
The Region of Waterloo council has approved using more than $15 million in capital funding to pay for a project that could offer a short-term solution to the ongoing water capacity issues. The project involves H2O Innovation Inc., a water and wastewater treatment company based in Oakville, installing three temporary ultrafiltration containers, each with an estimated flow rate of 50 litres per second, at the Mannheim Water Treatment Plant.
The Region of Waterloo relies heavily on groundwater for its municipal drinking water supply and regularly monitors for contaminants, including per- and polyfluoroalkyl (PFAS) such as perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). These “forever chemicals” have been detected in water systems across Canada and are subject to Health Canada drinking water guidelines.
As regulatory standards evolve and monitoring continues, the Region evaluates treatment options to ensure drinking water remains safe and meets provincial and federal requirements. Granular activated carbon (GAC) filtration is a recognized method for reducing PFAS concentrations and is one of the technologies commonly considered by water utilities when addressing these compounds.
The urgency of the situation was discussed during a recent community meeting. Kevin Thomason, vice-chair of the Grand River Environmental Network, warned that the system is running on a razor-thin margin.
“If there’s a water main break or something that may take out five per cent or ten per cent of our supply…that suddenly means taps are going dry and people aren’t getting service or a hospital isn’t getting water or a fire hydrant isn’t getting water,” Thomason said.
“So, we certainly don’t want to be running so close to our capacity,” he said.
The Waterloo Region staff members explain that any delays in approval could result in significant subsequent delays to project completion, which looks to regain lost capacity at that plant. They are seeking approvals before a detailed design gets completed.
The project costs will be included in the 2026 capital budget and funded through the Water Capital Reserve Fund.
The current-year costs of this project are significantly higher in the report presented to regional council at the Special Regional Council Meeting held on Friday, Feb. 6, 2026, compared to the projections detailed in a report from late January 2026. At that time, when the council was presented with a variety of potential options, the current-year impact on the capital budget was $2 million.
Projections for the total project cost remained around $16 million. The $2 million price for engineering services and $2.5 million for electrical work are preliminary estimates.
Beyond the immediate infrastructure bottleneck, a sedimentation capacity constraint at the Mannheim plant has choked the water supply by 300 litres per second, which revealed deeper concerns regarding the Waterloo Moraine.
Regional Councillor Joe Nowak plans to introduce a blue belt motion to provide permanent provincial protection for the Moraine’s high volume recharge areas (HVRAs). These specific, porous sections of land are the primary sponges that refill the region’s aquifers and the motion aims to shield them from urban sprawl to prevent long-term water depletion.
“We really need to look at this in conjunction with solving the capacity issue,” Nowak said. “Advocacy doesn’t have to be negative…we have this issue, we’re probably not going to be the only groundwater source community that has this issue.”
As the region pivots to this emergency implementation, Kenneth Brothers officially joined the Region on Feb. 23, 2026, as the Interim Commissioner of Water Services and Wastewater Operations. An internationally recognized professional engineer and a Fellow of the International Water Association, Brothers is tasked with overseeing the immediate repairs and fast-tracking the infrastructure upgrades needed to restore development capacity.
“Yes, we had a plan… but as with a lot of things, I think what we’re all seeing is there’s no holistic infrastructure plan that accompanies all of these things,” Brothers said.
During a Grand River Watershed community meeting on Feb. 6, 2026 regarding the impacts of Bill 23, experts discussed whether the region could simply tap into deep bedrock aquifers, which are water-bearing rock layers found deeply buried below the surface, to solve the water capacity issue.
Hydrogeologist Michael Friend and aquatic ecologist Jack Imhoff cautioned that this water is fundamentally different from the fresh, rain-fed “sponge” of the Waterloo Moraine.
Because this deep water resides in the Salina Formation, a prehistoric underground rock layer composed of ancient sea salt and gypsum, it absorbed extreme levels of salt over millennia. While technically fixable through desalination, the process is prohibitively expensive and produces a massive amount of toxic brine waste that the Region has no safe way to dispose of without damaging the watershed the meeting sought to protect.
“I look forward to joining the Region of Waterloo as we navigate through this pivotal moment,” Brothers said, emphasizing his commitment to “long-term water sustainability” for a population projected to reach one million by 2051.
