Lethbridge city council has unanimously approved borrowing up to $261 million for the largest infrastructure project in the city's history, and the repayment plan runs through your utility bill.
Council passed second and third readings of Bylaw 6534 on Monday, authorizing the borrowing for the Wastewater Treatment Plant Train 2 expansion over a term of up to 20 years, from the Province of Alberta or another authorized lender. The vote was unanimous.
The project adds 20 million litres a day of treatment capacity, a 50 per cent increase, along with a pre-treatment facility for industrial customers.
A plant from the 1980s running near its limit
The wastewater treatment plant was last expanded in the 1980s. It now serves more than 100,000 people and the system is operating close to capacity.
The city's case for moving now is blunt. Delaying means construction inflation, greater risk of a major failure, and a bigger bill later.
"The wastewater treatment plant is one of the City's most important pieces of infrastructure and supports homes, businesses, schools, hospitals and services across Lethbridge," Infrastructure Services director Joel Sanchez said when the project came to committee in May. "This project is about fixing and expanding critical infrastructure now rather than waiting for a larger and far more expensive problem later."
A major failure at the plant, he said, would carry significant environmental and financial consequences on top of the service disruption.
What it adds to your bill, year by year
The repayment is rate-funded, meaning wastewater users pay it down rather than property taxes. Rates rise 18.05 per cent annually for four consecutive years, 2027 through 2030.
For the average residential bill, the city's numbers work out to $4.42 more a month in 2027, another $5.21 in 2028, another $6.15 in 2029, and another $7.27 in 2030. By the end, the average household pays $23.05 a month more than today, roughly $277 a year.
The city's counterargument on affordability is real. Lethbridge currently has among the lowest wastewater rates in Alberta, about 60 per cent below the provincial average, and the city says rates remain comparatively low even after all four increases.
"This is the largest infrastructure project in the City's history, and it requires major investment," financial planning and budget manager Mitch Stevenson said in May. "We recognize that affordability is a real concern for residents. Investing now helps avoid much larger future costs tied to emergency repairs, construction inflation and system failures."
One gap worth noticing: the construction cost was presented in May at an estimated $285 million, funded through borrowings and reserves. The bylaw authorizes up to $261 million of borrowing, with the difference drawn from reserves.
Four years of 18 per cent compounds
The month-by-month framing is the gentle version of this schedule. Four consecutive annual increases of 18.05 per cent compound on each other, and compounding four times comes to roughly 94 per cent. By 2030, the wastewater line on a Lethbridge bill is close to double what it is today.
Both things the city says are still true. The starting rate is among the cheapest in Alberta, and it stays comparatively cheap after. But "cheapest in the province" and "doubling in four years" are both accurate descriptions of the same schedule, and residents deserve the second one alongside the first.
The councillor who wouldn't wait
This project wasn't scheduled yet. It sat in the queue for the 2027-2036 Capital Improvement Program.
At the May 13 Community Issues Committee meeting, Councillor Rajko Dodic moved to pull it forward and proceed immediately. The committee voted unanimously with him, for three recorded reasons: reduce the ongoing risk of major failure, get contractors involved early, and beat scheduling delays and cost escalation. Monday's borrowing vote finished what that motion started.
Nobody on council wanted to be on the record betting the old plant holds.
The money that signed two days later
On Wednesday, the Prime Minister and Premier signed the Canada-Alberta Housing Infrastructure Fund Agreement in Red Deer, putting more than $510 million federal plus up to $428 million provincial into exactly this category of project: municipal drinking water, wastewater, stormwater and solid waste. Alberta picks the projects, and the province's first list is due to Ottawa by November 30.
Lethbridge has just approved the largest wastewater project in its history, borrowing bylaw passed, early contractor involvement on the schedule, two days before that fund opened. Whether the city applies, and whether the province puts a shovel-ready $261 million plant on its first list, is now a live question for city hall. Every dollar that arrives from that fund is a dollar that doesn't come through wastewater rates.

Also at Monday's meeting
Mayor Blaine Hyggen gave a verbal update on the future of EMS in Lethbridge under the province's changed funding model, released as a separate statement. Council declared September 9 as International FASD Awareness Day on a motion from Councillor Belinda Crowson. First reading passed for a road right-of-way closure next to 1521 7 Avenue South, with a public hearing set for September 15 at 3 p.m.
