We have nearly 40 years combined experience evaluating soils across many Eastern Washington counties. While, we are licensed to design septic systems throughout the state of Washington, we focus on 8 Eastern Washington counties. We provide septic design services for Chelan, Douglas, Okanogan, Grant, Kittitas, Adams and Benton Counties.

Tower Designs was established in 2000 in Leavenworth, Washington. Our goal is to provide quality septic system designs and repairs for a reasonable fee. We are proud to stand by our work and guarantee an accurate assessment of the soils on your property. Most site assessments require machinery to dig a test pit.

We received prompt and professional assistance with our Septic repair project in record setting time! Keith helped us submit plans to the health department for approval and was most helpful in answering any questions we had! Highly recommend using Tower Designs for your septic design needs.

Do yourself a favor and find someone else to design your septic system, there's plenty of other great options in the area. Keith and his team don't care about you or whether you'll be able to use his design.
