Emptying septic tanks

The owner of a building located on the territory of the municipality must send, by any means, a copy of the invoice attesting that the emptying of his septic tank was carried out before October 1 of the year, each time such emptying is required.

We remind you that all septic tanks must be emptied according to the following frequency:

  • once every two years for a septic tank serving a permanently occupied building;
  • once every four years for a septic tank serving a seasonally occupied building.

In the meantime, it is possible to complete the declaration of the type of use or occupation of the building and send it to Nathalie Bouchard, environmental inspector at 1262 Mille-Isles Road, Mille-Isles (Quebec) J0R 1A0, by email at nbouchard@mille-isles.ca or by fax at 450-438-6157.

Failing to receive this proof of emptying, the Municipality sends a notice giving 15 days to remedy the situation. Failure to comply will result in penalties to the owner.
