Know Before You Go

About sewer overflows and what we're doing to help

The Kingston waterfront is a clean, safe place to swim, fish or boat. But you should know about the added risk of pollution that can occur after heavy rain fall.

Our partners at KFL&A Public Health caution that lake bacteria levels are higher after a heavy rainfall and swimming is not recommended for 48 hours.

During and after heavy rainfall, sewer overflow points may discharge diluted sewage into the environment and contribute to this pollution. Utilities Kingston now provides this information on a real-time map to help you make a better-informed decision about recreational water use. Consider this information along with public health precautions.

Questions or concerns? Call customer service, Monday to Friday, from 8 AM to 5 PM at 613-546-0000. You can also view a historical log of sewage overflows.

Warning: contact with polluted water can make people and pets sick.

Consider this information for at least 48 hours after a sewer overflow has occurred at a specific location. Check the map for status updates. The legend on the map explains the symbols to look for and what they mean to water users.
