ON Sewer was built for one kind of project: connecting Ontario homes to municipal sewer. When a connection notice arrives, or a homeowner is ready to leave their septic system behind, the work involves permits, locates, excavation, installation, plumbing, inspections, septic decommissioning and restoration. That usually means juggling several contractors. We bring it all under one team, with one accountable point of contact from the municipal service point to your home. As a specialized division of Monterra Earthworks & Site Services, we combine established excavation and site-servicing capability with a focus that is entirely on homeowners and residential connections.

How we work is simple. We review your property and give you a clear scope and price before anything starts. We plan around your landscaping, your driveway and your municipality’s inspection requirements. The most important part of the job ends up underground, so we document key installation details before the trench is closed, and you can see the work you’re paying for. A sewer connection is permanent, and we treat it that way, leaving your property the way we agreed.
