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.

Services
The type of septic system we can design for you depends on several factors. Primarily, the depth of soil above a restrictive layer ("hardpan", clay, water, etc.) on your property determines the type of system will be allowed. Gravity is our goal! Standard gravity septic systems are the simplest and least expensive type of system allowed in Washington State.
We know that getting your septic system designed is an important step in the process of building your new home, remodeling your existing home, or repairing an existing failed septic system. After setting up an appointment with us, we'll meet you at your property to gather the necessary information needed to begin the septic system design process.

Larry and his team were absolutely fantastic. We had a difficult property and he gave us a few options to make it work. Office staff were very friendly and called me back every time I had a question (which was a lot). I always felt like part of the process and look forward to using Apex in the future.

You should be able to give minus stars for companies like Apex Septic Design. Just finishing building a new home. This is the fifth home I have built in my life and contractors can be a real challenge at times. Some are also great to work with as well.
I have never worked with any company as bad as Apex Septic Design. It would take far too long to describe just how bad they were. They make a great first impression and they offer a large discount if you pay up front. What a huge mistake taking them up on that offer. Once they had the money I had to beg them to call or to get anything done month
