Water supply, wells and septic tanks

The issue of water is vital in assessing the quality and value of an immovable. Certain substances can contaminate drinking water. Their presence may be of natural origin or associated with human activities.

This section of the Guide deals with the contamination of drinking water from a lake, river, stream, spring or well, as well as water contamination by lead.


Contamination of drinking water from a lake, river, stream, spring or well

When a property is served by a municipal or private water supply system, it is the responsibility of the municipality or the system operator to regularly analyze the quality of the water to ensure that it is safe to drink.

But when the water supply source is a lake, river, stream, spring or well, this responsibility rests with the property owner.

However, owners are not subject to the same stringent rules as municipalities.

The role of the broker whose services have been enlisted to sell a property that is not served by a municipal water supply system is crucial. It is his responsibility to carry out verifications and obtain the documents required for the proper completion of the transaction.
