Experience You Can Count On
Founded in 2011 by Travis Buck, Advanced Septic Consulting has built a reputation for dependable septic design and development consulting services throughout the region. Together with Kurtice Lindsey and Chris Buck we specialize in onsite-wastewater treatment system design. Our team works closely with homeowners, builders, and developers to provide practical solutions tailored to each project.
While Advanced Septic Consulting has the ability to design septic systems anywhere in Washington, we primarily focus on serving Cowlitz, Wahkiakum, Lewis & Clark Counties, successfully designing and permitting hundreds of systems annually throughout Washington state. At Advanced Septic Consulting, we believe every project deserves careful planning, clear communication, and solutions designed specifically for the property and long-term success of each project.
