From site evaluations to final approval, we handle the details so you don’t have to.


Making Sense Of The Process

For many homeowners, the idea of designing a septic system can feel overwhelming - you’ve got to think about county regulations, soil requirements, and design options, and that’s a lot to sort through. That’s where we come in. Our team knows the local rules, understands the land in Battle Ground, and works directly with you to put together a design that’s both practical and approved, so no matter whether you need a perc test, drain field layout, or a complete aerobic system design, we make sure the process is straightforward.


Why Homeowners Trust McNair Septic 

When you choose McNair, you’re choosing more than a design - you’re choosing a partner. Here are just a few reasons families in Battle Ground call us first:


Generations of Experience

Our family has been designing septic systems in Washington since the 1970s - that’s over 40 years of knowledge applied to each project, so you can be confident your system will be reliable for years to come.


Licensed and Insured

We hold a Washington State On-Site Septic Designer license and carry full insurance, and you can rest assured that every design is completed by qualified professionals who meet state and county requirements.


Fast Turnaround

We know timing matters. Once you approve a bid, we can submit your septic design package for county review in as little as two weeks, and that means less waiting and fewer delays on your project.


Trusted Reputation

With hundreds of positive reviews and a near-perfect rating, our customers consistently praise our communication, problem-solving, and professionalism. We’re proud to have earned that trust one project at a time.


Tailored Designs For Every Property

Battle Ground has a mix of property types, from larger rural lots to smaller residential developments, and because no two sites are exactly alike, every design we prepare is based on the property itself - we don’t sell pre-packaged systems or push specific brands. Instead, we design for your soil, your layout, and your long-term needs. That might mean a gravity system for one homeowner and an advanced aerobic setup for another, and in the end, our only goal is to create a system that’s efficient, effective, and affordable for you.

Support From Start To Finish

We do more than just draft drawings - our team manages county paperwork, keeps you updated with clear timelines, and communicates openly about every step. By the time your septic system design is approved, you’ll understand exactly how it works and what to expect going forward.
