Request Septic DesignWhat Is Septic System Design?
Septic system design is the process of creating a custom wastewater system for your property based on soil conditions, property layout, and local health department requirements. Every system must be engineered to safely treat and disperse wastewater while meeting strict county and state regulations.
This includes evaluating your land, performing soil testing, and designing a system that will function properly for years to come.
If you’re not familiar with how these systems function, you can learn more about how septic systems work and what happens after the design phase.
Our Septic Design Process
1. Site Evaluation
We assess your property, layout, and proposed building location to determine the best placement for your septic system.
2. Soil Testing
Soil conditions play a critical role in septic performance. We conduct or coordinate soil testing to determine absorption rates and system requirements.
3. System Design
Based on your site and soil conditions, we design an engineered septic system that meets local regulations and fits your property.
Once the system is designed and installed, it’s important to understand how it operates over time. See our guide on how septic systems work for a full breakdown.
4. Permitting Support
We prepare the necessary documentation to help you obtain approval from your local health department.
