What we do
Our septic services
We handle installation, inspection, repair and Island Health filings for your property across the Comox Valley.
Septic System Installation
We design and install Type 1 and Type 2 systems sized to your lot, your soil and your household, and install Type 3 systems built to a professional's design.
Septic Inspection & Island Health Filing
We inspect your system, then file the paperwork Island Health requires — the Letter of Certification included.
Septic Repair
We diagnose failing drain fields, cracked risers and blocked distribution boxes, and fix what's actually wrong.
Riser & Distribution Box Service
We install risers and rebuild distribution boxes to current standards — the two repairs the CVRD's own rebate covers.
Septic Tank Pumping
Most tanks need a pump-out every 2 to 5 years. We pump yours out, check the tank while it's open and put you on a schedule.
What changes the price for your septic system?
When we design your system, we check your lot size, soil type, slope and bedroom count. Design and filing typically run $2,000 to $5,200 across BC. If your property sits in CVRD Electoral Area A, B or C, a maintenance rebate covers 75% of an inspection, riser or distribution box repair — up to $500, $400 or $200 — through 2028.

Where we serve
We serve Courtenay and the unsewered pockets around it — Black Creek, Royston, Union Bay and Merville, plus the smaller communities nearby. Royston and Union Bay are moving off septic under a planned CVRD sewer extension, though construction hasn't started yet. Until sewer arrives, you still rely on your septic system to keep your household running.

Frequently asked
Septic FAQ
How much does a septic system cost in Courtenay?
Design and filing typically run $2,000 to $5,200 across BC, and the system itself depends on your lot, soil and household size. We'll give you a firm number after we walk the property.
Do I need a permit for a septic system in the Comox Valley?
You don't need a municipal building permit for the septic system itself — it's filed directly with Island Health under the provincial Sewerage System Regulation, separate from any building permit your municipality issues.
Is there a rebate for septic maintenance in the Comox Valley?
If you're in CVRD Electoral Area A, B or C, the regional district's maintenance rebate covers 75% of the cost — up to $500 for an inspection, $400 for a riser or $200 for a distribution box — through 2028. It doesn't cover new installs or pump-outs.
How often should I pump my septic tank?
Most tanks need pumping every 2 to 5 years, depending on size and how many people are in the house. We can set you up with a maintenance schedule so you're not guessing.
Do you work outside Courtenay?
Yes — Courtenay is only part of our service area. We also serve your properties in Comox, Cumberland, Royston, Union Bay, Black Creek, Merville, Fanny Bay, Denman Island and Hornby Island.
What's a Letter of Certification, and do I need one?
It's the document that proves your system was installed to the filed design — Island Health requires it within 30 days of completion, and you'll want it on hand if you ever sell the property.
