Septic installation in Cobourg and Port Hope

Septic installation in Cobourg, Port Hope and most of Northumberland goes through the County's Plumbing and Sewage System office in Cobourg. North of the 401 the Oak Ridges Moraine sand drains fast; toward the lake the clay drains slowly, so the design changes from one side of the highway to the other. We install new systems and replace failed beds, and we file the permit for you.

New septic installation

Building a house, cottage or shop? You get a complete system sized for the bedrooms and fixtures you are actually putting in, designed to pass the inspection the first time.

  • ✓System design and the Part 8 permit application, handled by us
  • ✓Tank, distribution box and leaching bed installed
  • ✓Conventional bed, raised or filter bed, or tertiary unit, whichever the site needs
  • ✓All excavation, imported fill and backfill included
  • ✓Final grading and site restoration

Septic replacement

Old bed failing? Sewage surfacing, slow drains, a health unit order, or a system that predates the property? You get the old tank out and a new system to current Ontario Building Code, with the inspection coordinated for you.

  • ✓Old tank pumped, removed and disposed of
  • ✓Failed drain field, weeping bed or leaching bed excavated
  • ✓New system to current Part 8 code
  • ✓Health unit or building department inspections coordinated
  • ✓Site restored clean when we leave

We install conventional drain fields (weeping beds, leaching beds, tile beds), raised and filter beds where bedrock or the water table is close, and tertiary treatment units such as Waterloo Biofilter and Ecoflo where the lot or the shoreline calls for one.

We install and replace. We do not do pump-outs or minor repairs. If you only need a tank pumped or a baffle fixed, we will point you to someone who does that. If your system has failed or you are building new, we are the right call.

Septic in Cobourg and Port Hope: what changes here

Who issues the permit

Northumberland County's Plumbing and Sewage System officials issue Part 8 permits for the whole county except Trent Hills, from the County office at 600 William Street in Cobourg. Applications go in in person or by email. The County also runs a re-inspection service under By-Law 18-2022 that property owners and home buyers can book for an existing system. We prepare the application and book every inspection.

The ground you are on

North of the 401 the Oak Ridges Moraine is sand and gravel that drains fast, sometimes fast enough that treatment, not drainage, sets the design. Toward Lake Ontario the ground turns to heavier clay that drains slowly and needs a larger bed. Rice Lake shoreline lots bring setbacks on top. The test pit at the site visit tells us which you have.

The rule that shapes the design

If you are buying or selling a rural property here, the County's re-inspection is the honest way to find out what the existing system is worth before you close. If it fails, we quote the replacement in writing after one visit.

Septic installation in Cobourg and Port Hope: your questions answered

Who issues the septic permit in Cobourg or Port Hope?

Northumberland County, from its office at 600 William Street in Cobourg, for every municipality in the county except Trent Hills. We handle the application.

Can you check my system before I buy?

The County offers a re-inspection service for buyers and owners. We do not do inspections ourselves, but if the report says replace, we quote it in writing after one site visit.

Do you handle the septic permit?

Yes. We arrange the design and file the Part 8 sewage system permit with whichever office covers your property, a municipal building department or the health unit, and we book every inspection.

How much does a new septic system cost?

A conventional system for a typical home in Central Ontario runs about $15,000 to $30,000. Raised beds, tertiary units and difficult access push it higher. You get a written price after the site visit.

How long does an installation take?

Three to five days on site for most systems. Add the permit lead time in front of that, which we manage and keep you posted on.

How do I know my septic system is failing?

Sewage surfacing or a wet, spongy patch over the bed, slow drains through the whole house, gurgling, sewage smell outside, or an unusually green strip of lawn over the bed. If you see any of these, call. If it needs replacing we will tell you straight, and if it only needs a repair we will send you to someone who does repairs.

Do you install raised beds and tertiary systems?

Yes. Where bedrock, a high water table or a small lot rules out a conventional bed, we install raised and filter beds and tertiary treatment units such as Waterloo Biofilter and Ecoflo.

Can you install in winter?

Often, depending on frost depth and access. Frozen ground costs a bit more. If your system has failed and cannot wait for spring, call and we will tell you whether your site works in winter.
