Septic installation in Keene and Otonabee-South Monaghan

Septic installation in Keene and Otonabee-South Monaghan covers a township with no municipal sewage treatment, so nearly every home, farm and Rice Lake cottage depends on a private system. Between the drumlins, pockets of old glacial lake clay drain poorly, and the Township wants a measured T-time on every design. Homes in the Keene Heights and Crystal Springs wellhead areas also sit on a five-year inspection cycle.

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 Keene and Otonabee-South Monaghan: what changes here

Who issues the permit

The Township of Otonabee-South Monaghan has issued sewage system permits since Peterborough Public Health handed the program over in 2024, through Cloudpermit. A permit is needed to install or replace any part of a system up to 10,000 litres a day; larger systems are sewage works under a provincial approval. A complete application carries the designer and installer schedules and a percolation T-time from a soil testing agency. We assemble it and book the inspections.

The ground you are on

The county soil survey records a short-lived glacial lake in southern Otonabee township that left patches of clay, and the Simcoe soils formed there are poorly drained lake clay at the foot of the drumlins. North of the east end of Rice Lake, the Bondhead soils sit on steep-sided drumlins over a gently sloping moraine base. Clay and drumlin till take very different beds, so the T-time and a test pit come first.

The rule that shapes the design

OSM's Building By-law 2024-64 sets a Mandatory Sewage System Maintenance Inspection Program for two wellhead protection areas, the Keene Heights Subdivision and Crystal Springs, with inspections every five years starting in 2025. The wells there supply drinking water, so the septic beside them is watched. A system we install inside either area keeps its tank lids easy to reach, so that inspection is simple to pass.

Septic installation in Keene and Otonabee-South Monaghan: your questions answered

Who issues the septic permit in Otonabee-South Monaghan?

The Township's Building Department, through Cloudpermit. It took over new applications from Peterborough Public Health in 2024. We prepare the application, including the percolation test.

How close to Rice Lake can a new bed go?

OSM's zoning general provisions keep any new building or leaching bed 30 metres from the normal high water mark of a lake or watercourse. On shallow waterfront lots, that line decides the layout first.

I am adding a bedroom. Does the septic come into it?

Yes. OSM's septic guide lists added bedrooms and other changes to the house as triggers for a septic review before building. We check what your system can carry and size any replacement.

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.
