B&w On-site
For real estate sales/purchase contracts/development feasibility studies (formerly known as Perc or Perk test). Ranging from conventional gravity systems, pressure distribution to enhanced treatment systems and mounds. We work with a network of licensed professionals who can assist with your excavation and installation needs.

I have over 20 years of experience in the environmental field, with the last 14 years being in the on-site septic industry. I have been producing septic system designs in Spokane County, as well as evaluating test holes, reviewing design submittals and inspecting septic system installations as a regulator at a Local Health Jurisdiction in Washington.

I hold current credentials of an On-site Designer License and an On-site Inspector Certificate and I have provided soils evaluation instruction for other professionals working in the on-site septic industry. With an unmatched understanding of various septic development issues, I am here to help you navigate the permitting process in a stress free manner.
Services
I am a low overhead service provider, specializing in on-site septic system design in Spokane County. With my background as a licensed septic system inspector, I approach the septic system design process with the mindset of a regulator and take pride in producing high quality septic system designs and soils evaluation reports which meet all State requirements as well as those of the Spokane Regional Health District.
We'll provide you with the knowledge and guidance needed to purchase undeveloped land, permit a new septic system, expand an existing septic system, and repair or replace a failing septic system. Please provide the following information and I will contact you as soon as possible regarding your septic system design needs.

We received great service and were impressed with Bryan’s expertise and his ability to help us navigate the permitting process. We’ve recommended him to several of our friends.

B&W On-site helped me with my shop septic system. B&W’s recommendation saved me thousands of dollars over what my plumber had proposed. When I mentioned it to my plumber, he said B&W’s recommendation was a good one. I’d do business again.
