Serving the Cowichan Valley Regional District
Septic Service Across Rural Duncan and the Cowichan Valley
Duncan Septic Systems works the rural acreages around Duncan — Glenora, Sahtlam, Cowichan Station and out to Maple Bay — where heavy clay and high water tables decide what we can build. We install, repair, pump, and inspect these systems — typically $250 to $500 for a pump-out and $15,000 to $45,000 for a new system, with the Island Health filing handled for you.
A free on-site assessment confirms the exact system a Duncan-area lot needs — Type 3 systems for a sensitive site are custom quoted.
Rural Duncan runs on septic
The acreages that ring Duncan — Glenora, Sahtlam, Cowichan Station, and out toward Maple Bay — are almost all on private septic. We work these rural properties, where your soil, your slope and your well setbacks decide what the system needs.
Clay soils and the valley floor
The heavy clay across much of the valley floor drains slowly, so on many Duncan-area properties we put in a Type 2 treatment system instead of a plain tank and field. If your system is an older conventional one, the drain field is the part we expect to fail first.
Filed with Island Health
We design and install Type 1 and Type 2 systems ourselves, filing and certifying each one with Island Health under the Sewerage System Regulation. Where a site needs a Type 3 system, we install it built to a professional's design. Book a free assessment and we'll confirm what your acreage needs.
