Septic Design & Consulting in Klickitat County

Septic Design & Consulting Services in Klickitat County

When planning a new home, business, or property development in Klickitat County, septic design is one of the most important steps. At McNair Septic Design & Consulting, we bring three generations of experience to every project. Our team manages the entire process—from soil testing and site evaluations to design, permitting, and final approval—so you don’t have to juggle multiple contractors or county paperwork.

Our septic consulting services are built to handle a wide range of property needs. Whether your land requires a gravity system, sand filter, mound, pressure distribution, aerobic, subsurface drip, OSCAR II, or Glendon Pods system, we design based on what works best for your site—not what benefits a supplier. We’ve worked across Klickitat County in communities like White Salmon, Goldendale, Bingen, Lyle, and beyond, creating property-specific solutions that comply with local health department regulations.

One of the biggest advantages of working with McNair Septic is our streamlined permitting process. Once you approve your bid, we move fast—submitting for county review in as little as 14 days. This helps keep your project on schedule, whether you’re building a new home, adding an ADU, or preparing land for future development in Klickitat County.

Beyond septic design, we also provide consulting to homeowners who may be facing unique site challenges, existing system issues, or simply want expert advice before moving forward. Our transparent communication and proven process ensure you’re never left in the dark about your project’s status.
