With the recent significant rainfall received in Collingwood, the wastewater treatment plant (WWTP) is currently experiencing an overflow (full treatment bypass).
- An overflow (full bypass) at the WWTP started at 7:48 a.m. on April 15, 2026
- A partial bypass of the WWTP started at 6:00 a.m. on April 15, 2026
Monitoring, testing, and reporting are being completed as required. The Town will provide further details on the bypass when the event is over
What can residents do to help?
More rain is expected to arrive this afternoon, with overflows (bypasses) expected to continue throughout the day.
Residents: please limit your water use during this time to alleviate pressure on the system (WWTP). Avoid doing laundry, and limit showers and toilet flushing. Ensure your sump pumps are functioning properly. Controlled overflows like this can occur during heavy rain events to relieve the collection system and prevent sewage from backing up into homes and flooding basements.
If you have a backwater valve on your sanitary line, check that it is working properly throughout the day. If it is preventing system waste from entering your plumbing, your waste will not be able to drain out.
