Septic System Installation in Whatcom County

A septic system is designed around what the ground will accept. That is the whole logic of it. Two properties a mile apart in this county can need completely different systems and completely different budgets, because one sits on free draining glacial material and the other sits on heavy clay with groundwater two feet down in February.

So the process starts with digging test pits and reading the soil profile, not with picking a tank.

What comes out of that determines whether you get a conventional gravity system, a pressure distribution system, a sand filter, a mound, or something else. It also determines how much land the drain field needs and where on the lot it can go, which occasionally changes where the house can go.

Doing that work properly at the start is the difference between a system that lasts thirty years and one that is in trouble in eight. In wet ground there is very little margin for a design that was optimistic about drainage.

We do the evaluation, the design, the permit and the installation as one job. Splitting those across a designer, a contractor and the homeowner is the normal arrangement and it is where projects stall, because the gaps between them are nobody's responsibility.

We design for winter, not for the day we visited. A soil evaluation done in August tells you a great deal less about groundwater than one that accounts for what the site does in February. In this county that is a design input, not a footnote.

We are honest about permit timelines. They are what they are, they are not within our control, and building expectations around an optimistic version helps nobody.

And we hand you the as-built at the end and tell you to keep it somewhere findable. It is a five second piece of advice that saves the next owner a few hundred dollars and a lot of probing.
