Jim Henry Design Services

Jim Henry Design Services is based in Tumwater, Washington, a city adjacent to Olympia that borders some of Thurston County's most active residential development corridors. With a perfect 5-star rating from 4 customers, they've earned strong early reviews in what appears to be a design-focused septic specialty. The name and service category suggest this provider concentrates on system design rather than just pumping or maintenance, which fills an important gap in the local market. In a region where new builds, lot development, and system replacements require engineered designs before permits are issued, that specialty has real value.

Jim Henry Design Services focuses on septic system design, which involves assessing a property's soil conditions, lot size, and intended use to develop a system layout that meets Washington State and Thurston County health department requirements. A proper design determines the right tank size, drain field configuration, and setback distances from wells, property lines, and structures. This work is required before any new installation or major replacement can receive a permit. They may also assist with system evaluations and site assessments that feed into the design process, making them a useful first call for anyone planning a new build or replacing a failing system.

Jim Henry Design Services is located in Tumwater and serves the Thurston County region, including Olympia, Lacey, Tenino, and rural parcels throughout the county. Given the technical nature of system design work, they likely serve clients wherever a new septic permit is needed within their licensed service territory.
