Wells & Septic: What Buyers Must Check
If a property has a private well and septic system, get a water potability/quantity test and a septic inspection before your conditions expire — don’t rely on the seller’s word or the system's age alone.
This applies most directly to properties in Erin, Rural Erin, Mono, Amaranth and East Garafraxa, where most homes outside village cores are on private systems rather than municipal services.
How do I know if a property has a well or septic?
The listing or seller disclosure should state it, but always confirm directly — well records are often available from the Ontario well records database, and septic permits from the local health unit or township.
What does a septic inspection actually check?
A qualified inspector checks tank condition, the leaching bed, pumping history and signs of failure — this is different from a general home inspection and should be booked separately.
Can well water quality change after closing?
Yes — water quality can vary seasonally, so a single pre-closing test is a snapshot, not a guarantee. Some buyers arrange a second test after possession.
