Municipal wastewater consists of 99% water from stormwater and homes/businesses from washing, flushing etc. When a treatment plant or treatment process is overwhelmed, a bypass or overflow can occur. These events are often caused by heavy rainfall and/or snowmelt. During a by-pass or overflow, partially treated wastewater is diverted away from a treatment process to prevent backups, overflows or damage to the system.

Residents can help by conserving water by delaying or limiting unnecessary usage such as laundry, taking long showers or running the dishwasher during rain storms. You can also help by keeping our pipes clear - no wipes in the pipes!

City staff would like to thank residents for their assistance in reducing water usage during this time.
