Your soil decides which line you land on, not the salesperson. Below is where the money goes, and three real-world examples from our area.

Quick answer: conventional bed $25,000 to $40,000; filter bed $30,000 to $45,000; raised bed $30,000 to $50,000; advanced treatment $35,000 to $65,000 or more (2026). The soil test or test pit that starts the job is typically $700 to $1,200 on its own (source), and the permit fee is set by your town (see fees by town).
2026 septic cost by system type
| System | When you need it | Installed range |
|---|---|---|
| Conventional tank and leaching bed | Decent soil, water table well below the bed | $25,000 – $40,000 |
| Filter bed | Tighter lots, moderate soils | $30,000 – $45,000 |
| Raised bed | High water table or shallow bedrock: the bed comes up and sand comes in | $30,000 – $50,000 |
| Advanced treatment unit | Poor soils, small lots, some waterfront | $35,000 – $65,000+ |
These are installed planning ranges from SepticReplacement.ca’s 2026 Ontario cost guide, not quotes. Two neighbours on the same road can be $15,000 apart because of what is under the grass.
Where the money goes
| Item | Typical 2026 range | Notes |
|---|---|---|
| Soil evaluation / test pit | $800 – $1,800 | Needed before the permit |
| Design paperwork (if hired out) | $800 – $2,000 | Part 8 calculations, site plan, forms |
| Septic permit (your municipality) | $350 – $750 | Tiny, Tay, Midland and the rest issue their own |
| Septic tank, supplied and installed | $4,000 – $9,000 | Minimum 3,600 L for most homes |
| Leaching bed excavation and fill | $6,000 – $18,000 | The biggest variable: driven by the soil |
| Pump chamber and distribution | $2,000 – $6,000 | Raised and pressurized beds only |
| Engineering (complex lots) | $1,500 – $4,000 | Raised beds and advanced treatment |
| Advanced treatment unit | $8,000 – $18,000 | Includes electrical and setup; yearly service contract |
| Grading and basic restoration | $1,500 – $4,000 | Rough grade and topsoil, not landscaping |
| Inspections | $200 – $500 | Usually two or three visits |
| Old system removal | $1,000 – $3,000 | Often left off quotes: always ask |
Builder truth: a quote 25% below the others is usually missing a line from this table. Ask which one before you sign.

What moves the price in our area
- Sand versus water. Tiny’s sand drains well, which keeps many inland beds conventional. Near the shoreline the water table comes up and the bed has to come up with it.
- Rock. Parts of Tay, Severn and the Muskoka fringe hit bedrock early. Imported fill and a raised bed follow.
- Access. A long laneway or a tight waterfront lot means smaller machines and more hours.
- Bedrooms, not people. The Building Code sizes the system by bedroom count. Turning a den into a bedroom can make your current system too small.
- Setbacks. Distances from the well, the lake and the lot lines decide where the bed can go. See well and septic setback distances.
Design, permits and who does what
In Simcoe County the septic permit comes from your own municipality’s building department: the Township of Tiny, the Township of Tay, the Town of Midland and so on. The design is done by a qualified designer under Part 8 of the Building Code. For how design, permits and system types work, see SepticReplacement.ca, our Ontario septic guide, and the Simcoe County septic permit process.
We do the dig, the tank, the bed, the inspection and the restoration with our own crew and equipment, and we coordinate the paperwork so the install is legal before the first bucket goes in.

Frequently Asked Questions
How much does a septic system cost in Georgian Bay in 2026?
Most new and replacement systems land between $25,000 and $50,000. A conventional bed on good sand is $25,000 to $40,000; a raised or filter bed $30,000 to $50,000; advanced treatment $35,000 to $65,000 or more.
Who issues the septic permit?
Your municipality’s building department. In Tiny the Township’s approval agent is Tatham Engineering; Tay, Midland, Penetanguishene, Wasaga Beach, Collingwood, Oro-Medonte and Barrie handle their own.
Why are quotes so far apart?
Soil, access and what is included. Line up the quotes against the table above and the gap usually explains itself.
Can I replace just the tank?
Sometimes, if the bed is still healthy. Most failures are in the bed, though, and replacing only the tank does not fix a saturated bed.
