Residents on Fredericton's north side have been dealing with a persistent odour they link to the Barker Street Wastewater Plant. The smell has been present for months and, according to people who live nearby, can be strong enough that "if you breathe through your mouth, you almost taste it."
Marc Colwell, the City of Fredericton's wastewater treatment supervisor, says the volume going into the plant has risen as the city's population has grown. He gave figures showing annual biosolids around 4,500 tonnes when he started in 2019 and about 6,000 tonnes now. To handle the increased demand, the plant is running about 25 extra hours a week.
The city says it is making changes to how the facility operates to manage the issue. Colwell indicated staff are putting in extra hours and adjusting operations to keep up with flows. The report does not list specific technical changes or timelines for reducing odour beyond these operational adjustments.
Residents describe the odour as lasting and intrusive, particularly when sludge trucks pass. The combination of higher volumes processed, altered operating hours and weather patterns forms the city's explanation for why residents are noticing the smell more often now.
- The plant treats wastewater and generates biosolids that are recycled into topsoil.
- The plant is adding about 25 extra operating hours per week to cope with higher flows.
- Wind and atmospheric conditions determine whether odour reaches nearby homes.
The city acknowledged the problem and said it is changing operations, but the report does not provide a detailed timeline or technical plan for odour reduction, nor does it report measurements of odour levels or health assessments.
Residents near the Barker Street Wastewater Plant report persistent and sometimes intense odour that affects outdoor time. The city attributes the increased smell to higher wastewater flows, larger volumes of biosolids, longer operating hours, and weather conditions. Officials say they are adjusting plant operations to address the issue.
