Island Health Septic Filing in BC: Requirements, Setbacks and Certification

A filing, not a homeowner permit

There's no septic permit in BC that you pull yourself. Under the Sewerage System Regulation an Authorized Person has to design a new or altered system and file it with Island Health before anyone breaks ground. That person carries the job: they draw it up, they file it, and they answer for it being built the way it was filed.

When you need a filing

Every new system needs a filing, and so does any repair that changes the system — a new drain field, a field we've had to move, or a switch from one type to another. Swapping a pump or a lid doesn't. If you're not sure which side your job falls on, ask us.

Plan the septic before you buy or build

The right time to sort the septic out is before anything else is fixed. Buying a bare lot, we can walk it with you first — soil, water table, setbacks — so you know a system fits and roughly what it costs before the subjects come off. Planning a new house or adding a suite, the bedroom count sets the design flow, and the house, well and driveway all have to leave room for the field and its setbacks. Bring us in early and the filing is one line in your project schedule instead of the thing that holds it up.

ROWP or Professional?

A Registered Onsite Wastewater Practitioner — a ROWP — can plan, install and file Type 1 and Type 2 systems. That's us. Step up to a Type 3, or to a site that's genuinely complicated, and you need a professional, usually an engineer. Which one your job needs comes down to the type of system and what your lot looks like.

The maintenance plan requirement

Every system we file comes with a maintenance plan. The Authorized Person writes it, and it goes in with the Letter of Certification alongside an as-built diagram of what actually went into the ground. Keeping the system serviced to that plan is your job, and so is holding the records. Those records matter later, when a buyer's inspector asks how the system has been looked after.

How we file a septic system

1. 1

   Site and soil evaluation — we dig into the soil, run a perc test to see how fast the ground takes water, and find how high the winter water table climbs. That tells us what type of system your lot can carry.

2. 2

   System design and filing — we draw up Type 1 and Type 2 systems ourselves as a ROWP. For a Type 3 we bring in a professional, who does the design and the filing. Either way it's filed before anyone digs.

3. 3

   Construction to the filed design — we build it to match the filed plan, and we write down anything we had to change in the ground.

4. 4

   Letter of Certification — within 30 days of finishing we send Island Health the Letter of Certification, saying the system went in as designed. That's the paperwork that lets you use it.

5. 5

   Maintenance plan and records — every system we file comes with a maintenance plan, written by the Authorized Person and filed alongside the Letter of Certification. You keep the servicing records from there. Ask us and we'll confirm what your system needs and how often.

Owners cannot self-file

Only an Authorized Person can file a system with Island Health, so you can't file your own. If a system went into the ground without one, there's no Letter of Certification on it — which means you can't legally use it, and it will come up the day you try to sell. An Authorized Person has to draw it up, file it, and stand on site while it's built. Tell us what you're dealing with and we'll tell you where you stand.

Setbacks from wells, water and property lines

Setbacks are usually what decides where a system can go, and on a smaller Oceanside lot they can decide whether it fits at all. The Sewerage System Standard Practice Manual sets the minimum distances we design to — 30 m from a drain field to a domestic drinking water well, 30 m to a permanent creek or lake, 15 m to the ocean, and 3 m to a property line. Neighbouring wells count too, not just yours, and local bylaws or a covenant can push the numbers further out. We measure all of it during the site visit before we draw anything.
