Sewer Back Ups

InnServices Wastewater Operations Staff are on call (24 hours a day, 7 days a week) to deal with emergencies such as sewer backups.

  •  Call 705-436-3710 (8:30 a.m.- 4:30 p.m. Monday – Friday)
  • On Holidays, Evenings or Weekends – call 705-436-2141. You may need a licensed plumbing/drain contractor.

Once the operators have arrived, the property owner will be required to sign a “Sewer Servicing Agreement” prior to the commencement of any work.

If the problem with the sewer lateral exists on the private property side, then it is the property owners’ responsibility to call a licensed plumbing/drain contractor to perform any additional maintenance or rehabilitation work to address the cause of the blockage.

If there is a deficiency with the sewer lateral, and it is determined that the backup was caused by grease or materials such as diapers, paper towels or feminine hygiene products, the property owner will be responsible for having it removed.

If the problem with the lateral exists on the public property side, InnServices will make an assessment to determine if any additional remedial work is required.  Any work required on the public side will be scheduled and completed by the Town of Innisfil at no cost to the owner.  

Keep in mind that watermain breaks or sewer back-ups can be attributed to causes other than the Town’s failure to properly install or maintain its infrastructure. The weather, for example, can have a significant impact. The pressures created by the freeze/thaw cycles during the winter can also place a significant amount of strain on watermains. These pressures often result in leaks and ruptures. Severe weather systems that pass through the Town can also strain the sewer system. Significant rainfall over a short period of time can result in the Town’s storm and combined sewers taking in more water than they are designed to accommodate, resulting in sewer backups.

Because liability can never be assumed, the Town recommends that you first contact your home insurer before submitting a claim to the Town. If your insurer believes the Town is responsible for your damages, they may seek compensation against the Town on your behalf.

  • Do not dispose of paper towels, diapers and feminine hygiene products in your residential sewer line.   These products do not deteriorate quickly like bathroom tissue and should be disposed of in your garbage bin.
  • Avoid pouring cooking oil and grease down the sewer drain.  There is a common misconception that it is okay to wash grease down the drain with hot water.  In fact, the hot water will help to carry the grease down the drain, but quickly cools off as it flows into the sewer drain.  As it cools, it can solidify and clog the drain resulting in a sewer backup.
  • Review your residential insurance policy or contact your agent to determine if your policy covers damages due to sewer backups and/or water damage.  In many cases this additional coverage can be purchased at a minimal cost to cover your home in the event of a sewer back up incident.

“Before clearing a blocked sewer service line outside a house or building call Ontario One Call at 1-800-400-2255.  It is extremely important that you make sure no natural gas line intersects the sewer line before attempting to clear it.  Using rotating or water jetting equipment to clear a blocked sewer line can damage a natural gas line and cause a serious gas leak. Ontario One Call offers free Natural Gas Sewer Safety Inspections on behalf of Enbridge.  Inspections are offered throughout the Enbridge Gas Distribution service area, even if you are not a natural gas customer.”
