Septic installation in Gravenhurst and Bracebridge

Septic installation in Gravenhurst, Bracebridge and Muskoka Lakes is Shield work: granite close to the surface, lake setbacks, and cottage lots that were built before today's code. We install new systems and replace old beds, raising them on certified fill where the soil is too thin for a conventional bed. We file the permit with your town or township and book every inspection.

  • ✓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 Gravenhurst and Bracebridge: what changes here

Who issues the permit

Each Muskoka municipality issues its own Part 8 sewage system permit: the Town of Gravenhurst, the Town of Bracebridge and the Township of Muskoka Lakes each have a building department that handles it. We file with the one that covers your lot and book every inspection.

The ground you are on

This is Canadian Shield. Granite surfaces as outcrops and the soil over it is often too shallow for a conventional bed. The Building Code requires 900 millimetres of unsaturated soil between the bottom of the bed and bedrock, so most new systems here are raised beds built with imported certified fill, and some lots need rock broken to seat the tank. Small waterfront lots often call for a tertiary unit such as Waterloo Biofilter or Ecoflo to meet setbacks.

The rule that shapes the design

Shoreline setbacks on Lake Muskoka, Lake Joseph, Lake Rosseau and the smaller lakes decide where a bed can go before anything else does. A replacement on an old cottage lot is designed to current setbacks, and we plan the barge or road access with you before the crew arrives.

Septic installation in Gravenhurst and Bracebridge: your questions answered

Who issues the septic permit in Muskoka?

The building department of the municipality your lot is in: Gravenhurst, Bracebridge or Muskoka Lakes. We handle the application and the inspections.

Is a raised bed the only option on rock?

It is the usual answer where bedrock is shallow. Where the lot is too small or too close to the water for any bed, a tertiary treatment unit lets the system meet code in less space. The site visit tells us which.

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.
