How Much Does a New Septic System Cost in NC?

Typical ranges

What drives the number

• Soil and water table. Tight or wet ground may require a mound or advanced treatment system, which costs more than a simple gravity field.
• System size. The county sizes the system to the number of bedrooms.
• Site conditions. Access, slope, and how far the field sits from the tank all factor in.

What a complete estimate should include

Soil evaluation, the county/state permit, the tank, the drain field, and installation to North Carolina standards - all in one written number. Be wary of a low headline that leaves out the permit or the field. Ask for the all-in price after a site visit.
