The Municipality of Kincardine says odour conditions are improving at its wastewater lagoons after an electrical issue forced the aeration system offline for approximately one week.
The interruption resulted in unpleasant odours near the treatment facility and in surrounding areas, including the Stonehaven subdivision.
In an update issued Tuesday, November 10, 2026, the municipality confirmed both aeration blowers are back in operation.
"The two aeration blowers have since been restarted, and conditions are improving. Staff reported no noticeable odours during their most recent site inspection," the municipality reported.
As of November 9, dissolved oxygen levels in the lagoon had returned to approximately 1.6 milligrams per litre, indicating improved treatment conditions.
Air quality monitoring continues around the clock, with recent hydrogen sulphide readings remaining well below the alarm threshold used for confined-space work.
Meanwhile, sludge removal continues at the facility, with approximately 430 dry tonnes removed toward this year's target of 900 tonnes.
The work is expected to continue until November 30.
The municipality is also reviewing treatment data with engineers and equipment suppliers to identify longer-term improvements.
The multi-year sludge removal project is intended to restore treatment capacity and address ongoing operational challenges at the wastewater lagoons.
