Septic Maintenance

In an effort to protect the Lake Simcoe watershed and York Region drinking water wells, the Province of Ontario, through the Ontario Building Code, now mandates that all properties with septic systems located within 100 meters of the Lake Simcoe shoreline, water courses within the Lake Simcoe watershed, and septic systems located within an area around a York Region drinking water well must have a septic system maintenance inspection completed every 5 years. East Gwillimbury’s program requires residents to hire an inspection professional to complete the inspections. Affected residents will receive notification in the mail with next steps and a list of FAQs.

Maintenance Tips and Reminders

  • Pumping your tank on a regular basis is the most important step you can take to ensure the health of your family and surrounding properties.
  • A family of four with a 1000 gallon tank (1400 Litre) would normally pump every two years. While your tank is being pumped, be sure to have your contractor check that the inflow and outlet pipes are free of blockages, and all required baffles are in place. 
  • Keep a detailed record of repairs, pumpings, inspections, permits issued, and other maintenance activities.
  • If you have only a private sewage disposal system holding tank (with no leaching bed) you will need to pump more often, as frequently as every week or two, depending on usage and size of tank.
  • Conserve water
  • Avoid septic stimulators and additives
  • Give your septic system a healthy diet
  • Take precautions to protect your system -- don’t drive or park vehicles on top of your drainfield
  • The following items should be avoided, do not:
  • Plant trees or shrubs too close to your field or tank. Roots can cause damage and clog your drainfield (especially willows, silver maples and poplars)
  • Change your lot's drainage pattern.
  • Bury your drainfield under landscaping materials (such as plastic) or pavement; water must evaporate from the drain field for it to work efficiently.
  • Bury your septic tank under a driveway or deck, making it inaccessible for inspections and pumping.
