Services & Process

The core of this business is septic system design, which means evaluating a site's soil conditions through percolation testing, determining the appropriate system type, and producing the engineered drawings required by Pierce County Environmental Health for permits. This work is essential for new home construction, property additions, or system replacements that require county approval. Randy also assists clients who need a site assessment before purchasing land, helping buyers understand whether a lot can legally support a septic system before they commit to a purchase.

Frequently Asked Questions

Why do I need a septic designer for my new construction project in Pierce County?
Pierce County requires a permitted septic system design before a new home or structure can be connected to an on-site system. A licensed designer performs the soil testing and prepares the engineering documents that the county reviews and approves. Without this step, you can't get a building permit.
What is a percolation test and why does it matter?
A perc test measures how quickly water drains through the soil at your site, which determines what type of septic system can be used and how large the drain field needs to be. Soils that drain too slowly or too quickly may require a non-standard system design. The results directly shape every decision in the design process.
How long does the septic design and permitting process take in Pierce County?
It varies depending on site complexity and county workload, but plan for several weeks from initial soil testing to permit approval. Complicated sites, like those with steep slopes or marginal soils, may take longer if revisions are needed. Starting the design process early in your project timeline avoids construction delays.
Can I use an existing septic design if I'm replacing a failed system?
Not usually. If your existing system was installed years ago, the original design may not meet current Pierce County standards, and a failed system almost always requires a new permitted design before replacement work can begin. A fresh assessment ensures the new system is properly sized and sited for current conditions.
What types of septic systems are commonly designed for Pierce County properties?
Conventional gravity systems work well on lots with good soil drainage and adequate space, but many Pierce County properties require alternatives like pressure distribution, mound systems, or drip irrigation systems due to high groundwater, clay soils, or limited space. The right choice depends entirely on your specific site conditions.
Do I need a designer if I'm just repairing part of my existing system?
Minor repairs like replacing a broken pipe or a failing pump often don't require a new design, but more significant work like drain field expansion or tank replacement may trigger a permit requirement. Checking with Pierce County Environmental Health before starting any major repair work is always a good idea.
