Home


As we monitor the unprecedented developments of the COVID-19 pandemic and its impact on the community we serve. Our hearts and thoughts go out to all those affected personally. We applaud the healthcare workers, local communities, and governments around the state of WA on the front lines working to contain this outbreak.

After great consideration, we have decided to remain open as our business doesn’t require us to have personal contact with our clients. In the event that a client would like to have personal contact with Brad, we will maintain all recommended safety requirements outlined by Gov. Inslee and the Health Organization.

As we work closely with the Health Dept., if anything changes we will address it at that time. In the mean time, our operational hours will remain the same for your septic feasibility / design needs.

With kindest regards,
Jennifer Scherz / Davis
