Frequently Asked Questions

How much does a new septic system cost in Georgia?

A conventional septic system typically costs $15,000 to $30,000, depending on local permitting complexity, soil conditions, and labor costs. Alternative systems (mound systems, drip irrigation, FAST systems) required in certain areas cost even more.

What permits are needed for septic installation in Georgia?

You need a Soil Evaluation approval from your local board of health and a Construction Permit before installation. All work must comply with Ga. Comp. R. & Regs. Chapter 511-3-1 (On-Site Sewage Management Systems), administered by Georgia DPH. In some areas, additional regional commission approvals may be required. The permitting process typically takes 2-4 months.

How long does septic system installation take in Georgia?

The physical installation usually takes 3-7 days for a conventional system. However, the entire process from initial soil testing through final inspection can take 3-6 months due to comprehensive permitting requirements.

What type of septic system do I need in Georgia?

The system type is largely determined by Georgia DPH and your local board of health based on soil percolation results, lot size, setback distances, and proximity to wells or water bodies. Many properties in certain areas require alternative systems due to high water tables, poorly draining soils, or tight lot configurations.
