A septic system design is a detailed plan showing how your septic tank and drain field will be installed based on your soil type, property layout, and local regulations. It’s required before you can get a permit to install a septic system. In the Southeast, where soil conditions vary, a professional design ensures the system functions properly and avoids future issues.

Design costs typically range from $500 to $1,500, depending on the complexity of your lot, soil testing, and local regulations. We provide flat-rate pricing with no hidden fees, so you know what to expect.

Generally, 2 to 4 weeks, depending on how quickly the local health department processes permits. We aim to complete designs within 7–10 business days once all site info and soil data are collected.

You'll need a property survey or plat map, site access for soil testing, any house plans or layout info. We'll handle the rest, including soil tests, layout planning, and coordinating with your county health department.

Yes, to a degree. We’ll try to work around your preferences, but soil conditions, setbacks (from wells, property lines, etc.), and slopes dictate placement. We’ll walk you through the options.

If your soil doesn't absorb water properly, we may need to design an alternative system like a mound, ATU (aerobic treatment unit), or a pumped system. We’ll explain all your options and costs clearly before moving forward.

If the changes affect bedroom count, square footage, or layout, yes—your septic design must match your final building plans. Minor changes might not require a full redesign.

Traditional systems use gravity and require good soil. Alternative systems (e.g., mound, drip, or aerobic) are used when the soil doesn’t drain well or if space is limited.

Absolutely. We design gravity, pump, aerobic, drip, and mound systems, depending on site needs. We’ll work with you to meet code while keeping the install practical.

Yes. We consider contractor-friendly layouts, cost-efficient materials, and system types to avoid overengineering. We can design around preferred tank types or layouts when possible.

Yes. Some contractors prefer we work behind the scenes, while others want us to handle all homeowner communication. Either way, we’ll keep you looped in.

Yes. We offer system re-evaluations and redesigns for additions, garage conversions, or added bedrooms to help meet updated code requirements.
