Septic Systems

If you own a property with a septic system in the Town of Stouffville, you need to have septic system maintenance completed every five years if your property is within 100 m of:

• Any river or stream that continually flows in an average year
• Any lake or pond that is connected on the surface to a river or stream
• Any other lake or pond that has a surface area greater than eight hectares
• The Lake Simcoe shoreline

Septic system maintenance helps protect the environment and our drinking water while supporting the Clean Water Act and the Lake Simcoe Protection Plan.

View our sewage maintenance inspection map to find out if your property requires mandatory septic system inspections.

After completing your septic system inspection, please send a certificate of inspection to us at septic.inspections@townofws.ca
