Lagoon Sludge Removal Project – November 10, 2026 Update

Work continues at the Municipality of Kincardine's wastewater lagoons as crews make progress on sludge removal and ongoing treatment improvements.

Aeration and Odour Management

Recent electrical supply issues required the temporary shutdown of the lagoon's aeration blowers for approximately one week. During this interruption, odours were reported near the site and in portions of the surrounding community, including the Stonehaven subdivision.

The two aeration blowers have since been restarted, and conditions are improving. As of November 9, dissolved oxygen levels had returned to approximately 1.6 mg/L, a positive indicator for the treatment process. Staff reported no noticeable odours during their most recent site inspection.

Air quality monitoring continues 24 hours a day near the aeration cell and incoming wastewater, where odours are most likely to occur. Recent monitoring results have shown hydrogen sulphide (H₂S) levels well below the alarm threshold used for confined-space work. Staff continue to monitor conditions closely.

The Municipality is also reviewing treatment data collected over recent months with its engineering team and aeration equipment supplier to identify opportunities for longer-term improvements.

Sludge Removal Progress

Sludge removal work is progressing well. As of November 9, approximately 430 dry tonnes of sludge had been removed, toward a target of 900 dry tonnes for 2026.

Work remains underway, with the project currently anticipated to conclude November 30, 2026.

The Municipality appreciates residents' patience as this important work continues and remains committed to providing updates as conditions and project milestones change.
