Septic systems for Nanaimo homes with no sewer connection
Septic service where there is no sewer
Nanaimo Septic Systems designs, installs and repairs onsite wastewater systems across Cedar, Lantzville, Nanoose Bay and Gabriola Island. Every new system is filed with Island Health by an Authorized Person before construction, then certified within 30 days of completion. Most tanks in the Regional District of Nanaimo need pumping every 3 to 5 years.
Cedar, Yellow Point, Lantzville, Nanoose Bay and Gabriola Island — acreage and island properties where the soil, the well and the setbacks decide what can be built.
Serving the mid-Island
- Filed before it is dug
- Every new system is filed with Island Health by an Authorized Person before construction, as the Sewerage System Regulation requires.
- Type set by the soil
- Type 1, Type 2 and Type 3 are defined by effluent quality, not by brand of equipment. The site decides which one applies.
- Wells come first
- A 30 m separation between a disposal field and a domestic water well drives the siting of most rural systems in this area.
- Built where there is no sewer
- Cedar, Nanoose Bay and Gabriola Island sit outside every Regional District of Nanaimo sewer service area.
Service lines
Four kinds of septic work
Four service lines, in the order most properties meet them.
New system installation
Soil assessment, design, filing with Island Health, construction and certification.
System inspections
Tank condition, disposal field performance, and the paperwork a property should already hold.
Field repairs
Diagnosis first — then a component repair, or a filed replacement field.
Tank servicing
Pumping, effluent filters, risers, and a maintenance interval that gets written down.
Process
From soil test to Letter of Certification
- Step 1
Site and soil assessment
soil depth, slope, drainage and any sign of a high winter water table, plus the position of every well and property line.
- Step 2
System type and design
Type 1, Type 2 or Type 3, chosen from what the ground and the setbacks allow, with the design prepared by an Authorized Person.
- Step 3
Filing with Island Health
the Record of Sewerage System, plans and a scaled site plan, filed before any excavation starts.
- Step 4
Installation and certification
construction, then a Letter of Certification with an as-built diagram and a maintenance plan within 30 days.

Where the sewer lines stop
Coverage across the electoral areas and Lantzville
Ground here is layered rather than uniform. A Geological Survey of Canada model of the Nanaimo Lowland describes Quadra Sand more than 75 m thick in places, sitting beneath Vashon Drift till up to 30 m thick, over a clayey silt aquitard. Soil depth can change across a single property, which is why a test pit at one corner does not describe the other. On Gabriola Island the rock is fractured sandstone instead, and the island's own community plan reports known problems with percolation for septic disposal.

Frequently asked
Common questions about onsite systems
- Does every property outside the city need its own system?
- Almost every one. Sewer in the electoral areas exists only as small pockets — the Cedar service area covers 128 properties, Fairwinds 796 — and those boundaries were drawn around development that already existed rather than around future need. A property outside one treats and disposes on site, however close the pipe happens to run.
- Who is responsible if a filed system fails?
- The Authorized Person who designed and signed the filing is responsible for the design, because Island Health neither approves designs nor inspects the work. Ongoing operation sits with the property owner, following the maintenance plan filed alongside the Letter of Certification.
- What is the first step on a new build?
- Test pits. Soil depth, slope and the position of every well and property line are measured before a design exists, because those measurements are what determine the effluent standard, the field type and the area required.
- Does adding bedrooms affect the septic system?
- Usually. A system is designed for a specific daily flow, so an addition that increases the number of bedrooms generally means the design has to be revisited by an Authorized Person and the change filed.
- Is a septic system a problem when selling?
- Not inherently. What buyers ask for is the paperwork — the filing, the Letter of Certification, the maintenance plan and pump-out records. Island Health releases existing records for a property for $50.
- What does maintenance actually involve?
- Pumping every 3 to 5 years for most tanks, according to the Regional District of Nanaimo, plus cleaning or fitting an effluent filter and keeping lids reachable. A Type 2 or Type 3 system carries additional servicing in its filed maintenance plan.
