Typical septic installation prices.
These are the average installation ranges Tim supplied in October 2026 for planning a project around Prince George. They are not fixed quotes, repair prices or a guarantee that a system is suitable for your property.
| Installation | Typical range (CAD) | Learn about the layout |
|---|---|---|
| Gravity field | $25,000–$35,000 | Gravity fields |
| Pressure system | $35,000–$45,000 | Pressure distribution |
| Sand mound | $45,000–$55,000 | Sand mounds & raised beds |
Confirm inclusions and tax. The scope, site conditions, design, materials and access affect the price. Ask Tim to identify what is included and the applicable GST in your written estimate. These ranges do not state that tax is included.

Different problems. Different scopes.
There is no useful single price for “septic work”. Before comparing estimates, establish what is being exposed, repaired, installed or replaced. Northern Septics focuses on the excavator work; pumping and routine mechanical servicing are separate.
| Project | What changes the excavation cost |
|---|---|
| Damaged buried pipe | Length and depth, access, rock or roots, affected connections and the surface to reinstate. |
| Tank installation or replacement | Excavation, selected tank and placement method, removal responsibilities, base preparation and backfill. |
| Field repair or replacement | Localised repair versus reconstruction, field layout, design, soil conditions, area and specified materials. |
| Lagoon installation or earthworks | Defined work area, inlet or embankment scope, design, material movement, lining and work by others. |
| Tank lids, risers and access excavation | Tank depth and location, compatible replacement parts, excavation limits, removal and reinstatement. |
| Distribution box replacement | Access, depth, specified component, connected pipework and backfill. |
| Old tank removal or decommissioning | Agreed method, tank condition, lifting or transport, handling by others and backfill. Pumping is separate. |
| Buried access or test pits | Machine mobilisation, known locations, working room, depth and who directs the investigation. |
Ask what the estimate includes.
- Travel, mobilisation and minimum machine time.
- Operator time and the exact excavation limits.
- Material supply, delivery and any removed spoil.
- Existing tank handling and any work by another provider.
- Backfill, final surface and the extent of reinstatement.
- Design, assessment, testing, documentation and applicable tax.
A quote for digging access should not be compared with a quote that also includes replacement materials and finished reinstatement. Ask where the work starts and ends.
Get a price for your property.
Send Tim your property area, the problem or proposed work, access photos and any drawings or findings. If a defect has not been identified, say that too. A symptom on its own is not a complete excavation scope.
Prices and any applicable tax are confirmed in your estimate. The installation ranges above are a starting point; contact Tim for current pricing for the actual work.
