Professional engineering and design of septic systems tailored to your property's soil conditions, water table, lot size, and local code requirements.
Septic system design is the engineering phase that determines the type, size, and layout of your septic system. A properly designed system matched to your property's specific conditions will perform reliably for decades.
What Goes Into Septic Design
- Soil analysis: Percolation tests and soil borings determine how well your soil absorbs water.
- Site survey: Mapping the property to identify setback requirements, slopes, water features, and utilities.
- System sizing: Calculating the tank size and drain field area based on the number of bedrooms, estimated water usage, and soil capacity.
- System type selection: Choosing between conventional, mound, chamber, aerobic, or other system types based on site conditions.
- Engineering drawings: Detailed plans showing exact placement, elevations, and construction specifications.
Why Design Matters
A poorly designed system can fail prematurely, contaminate groundwater, or violate local codes. Professional design ensures your system meets all regulatory requirements and will function properly for its expected lifespan.
