How much does a septic system cost?

The right budget depends on the site, expected use, treatment requirements, field layout, access and excavation. Remote transport can be a significant part of an island project. A site visit is the starting point for a useful estimate; we explain the proposed scope before you commit to construction.

How long does the process take?

Timing depends on site investigation, design, filing, equipment availability and the construction schedule. In BC, an authorized person files system information with the health authority before construction; this is not a conventional permit approval process for an ordinary septic system. We discuss the steps and a realistic schedule for your particular project.

What happens at the first site visit?

We talk about your building plans, occupancy and future uses, then review access, existing system information and possible field locations. Test pits and soil assessment help establish what the ground can support. Bring any existing septic records, survey or building plans you have.

What is the difference between Type 1, 2 and 3?

Type 1 uses a septic tank and dispersal field. Type 2 adds treatment to achieve a higher effluent quality. Type 3 achieves a further defined treatment standard and requires professional involvement. Treatment type and field layout are selected for the property, rather than chosen from a one-size-fits-all package.

Do I need a Registered Onsite Wastewater Practitioner?

BC’s Sewerage System Regulation requires an authorized person for Type 1 and 2 construction and maintenance, or an owner working under their supervision. Type 3 work requires supervision by a qualified professional. Mike is a Registered Onsite Wastewater Practitioner; engineering is coordinated where the project requires it.

How often should my system be maintained?

Follow the maintenance plan supplied for your system and keep service records. The interval depends on treatment equipment, pumps, usage and site conditions. Tank pumping and system servicing are different tasks. We can review the records and help identify the appropriate next service.

Can you work on islands or properties with difficult access?

Yes. Our project photos include island excavation, barge access, tank placement and bulk material handling. Tell us about the landing, access route, slopes and site restrictions early so logistics can be considered alongside the system itself.

Do I need a new system if I add a suite or bedrooms?

A change in occupancy or building use can change the wastewater design requirements. The existing system should be assessed before you rely on it for a renovation, suite or additional dwelling. We review the records and site to work out the next step.

Can Type 2 treatment reduce the field size?

It can reduce the required infiltrative area when the site supports a higher hydraulic loading rate. Minimum contour length is a separate consideration, so the field may become narrower without becoming shorter. See our Type 1, 2 and 3 explanation for a worked example.

Can a failing system be repaired?

Sometimes a component can be repaired or replaced; other situations call for a new dispersal field or system. An assessment helps separate pump, control, pipe, tank and field problems before a scope is chosen. Contact us if you see backups, persistent odours or unexpected wet areas.
