Implementation of Night-Shift Dredging Operations and Extension of In-Water Work Permit
The Town of The Blue Mountains would like to provide the public with an update on the schedule for the remaining work on the installation of the new outfall for the Thornbury Wastewater Treatment Plant.
The project contractor has recently implemented a three-barge operation to increase the rate of offshore trenching and dredging work. Despite these additional resources, challenging lakebed conditions, water conditions and machinery downtime continue to affect daily production rates.
To help advance the work, the contractor will be introducing night-shift dredging operations beginning Friday, September 11. The night shift will operate from 7:00 p.m. to 7:00 a.m. using the primary barge and excavator only. This approach will allow offshore trenching activities to operate on a near-continuous basis, subject to weather conditions and established safety requirements. Overnight work will begin approximately 290 metres offshore and will progress into deeper water over time. Work closer to the shoreline will be completed during daytime hours only. All work will continue to be carried out in accordance with applicable approvals and environmental protection measures.
The public may notice additional activity and lighting associated with the offshore work during overnight hours. The Town recognizes this may affect nearby residents and lake users and appreciates the community’s patience as the project team works to complete this critical infrastructure project.
The Town has also received approval from the Department of Fisheries and Oceans, Ministry of Natural Resources and Grey Sauble Conservation Authority to extend the in-water work permit until Wednesday, October 14, 2026.
The Town, its engineering consultant and contractors remain committed to completing the work as efficiently and safely as possible. Project updates will continue to be posted to the Town’s project web page and emailed directly to project subscribers.
