Sanitary Sewer Main Flushing Notification

The City of Kawartha Lakes wishes to inform residents and businesses that regular scheduled sanitary sewer main maintenance will be taking place in various areas of Lindsay, Fenelon Falls, Bobcaygeon, Omemee, and Coboconk Wastewater Collection Systems to remove settled and accumulated material. Work will be undertaken Monday to Friday starting Monday September 19th, 2016 from 7am to 7pm and will continue until the end of November 2016. Some high traffic areas will be flushed after 7pm to avoid busy traffic and ensure contractor safety.

Please be advised that during this process the contractor (The Pipe Spy) will be setting up their apparatus at each manhole in the roadway and releasing pressurized water through the sanitary sewer main pipe to remove any buildup. Preventative maintenance involves the flushing of sanitary sewer mains to remove settled and accumulated material as well as to eliminate the potential for sanitary sewer main surcharging (or an overloading of the sewer beyond its design capacity), which can result in damage to property.

During these events residents may experience a bubbling and/or vacuum effect in drains and toilets. It is recommended that residents keep all toilet seats closed and cover any floor drains. In order to prevent sewer gasses from migrating into homes, internal plumbing includes traps that hold a volume of water. During the flushing process, it is possible for the negative pressure created in the sanitary sewer main to draw this water out of the traps and allow sewer gasses to enter the home. For this reason, it is important for homeowners to refill these traps by running the water in their sinks and into floor drains (i.e. with a garden hose) after the work has been completed.

The City asks that all residents remain patient during this process. Should you have any questions or concerns, please call the Water and Wastewater Division at 705 324 9411 extension 1121.
