Most homeowners in Roswell, GA can expect to pay between $6,000 and $12,485 for a typical septic tank installation, which usually includes the tank, drain field, and labor.
Higher costs generally stem from advanced system types (like aerobic, drip, or spray systems), difficult soil conditions requiring more extensive drain fields, larger tanks, poor site accessibility, and the need for additional components such as risers or pumps.
Advanced septic systems, such as aerobic, drip, or spray, typically fall into the premium price tier of $10,001–$15,000, which includes the tank, field, labor, and often sod. Basic installations can be as low as $3,200–$6,000.
Yes, concrete tanks are roughly $1,200-$1,500 for the tank alone, while plastic tanks can run about $500 more. These figures do not include installation or other components like risers.
Labor costs for site survey, excavation, tank placement, and drain field installation are typically integrated into the overall project cost. The complexity of the site and system type will dictate the labor hours required, which in turn influences the final price.
