Welcome to Apex Septic Design, owned and operated by Larry Purdum. Our goal at Apex is to provide you with the best septic design and maintenance services possible. We are licensed Washington State Onsite Wastewater Treatment System Designers with over 10 years of experience in the Western Washington septic design and maintenance industry. We are Puget Sound natives and avid outdoorsmen, which gives us knowledge and understanding of the soil, water, and weather conditions that affect septic system design and maintenance in the Puget Sound area.
We stick by our motto: “Better by Design” We want to design for you the least expensive, longest lasting type of septic system allowed by state and local codes. The less you have to pay for the system, the happier we are. We have years of experience designing everything from simple gravity-flow systems, to complicated high-volume commercial systems. Whether it is a conventional gravity system, or a more complex alternative system, we want to design a system for you that will meet your needs for years to come.
