Septic permits in Duncan
In South Carolina, septic permits come from the state, through the SC Department of Environmental Services, rather than from the county. That applies in Duncan and across Spartanburg County.
A site evaluation comes first to confirm the soil can support a system. The permit then covers the specific system to be installed, and the finished installation is inspected before it is approved for use.
We handle permit acquisition and inspection coordination as part of every installation, so you are not chasing paperwork.
South Carolina septic work is performed under On-Site Wastewater Installer License #OSWWI0812 (Tier 2).
Newer neighborhoods and established homes
In built-up areas the jobs are usually about fixing and adding: regrading a yard that holds water, trenching for a new utility line or outbuilding, or replacing a septic system that has reached the end of its life on a property outside sewer service. We keep the footprint small and leave the site clean.

Common Questions
Who issues septic permits in Duncan, SC?
The SC Department of Environmental Services. In South Carolina septic permits are issued at the state level, not by the county. We handle the permit and inspection coordination for you.
My yard in Duncan holds water after it rains. Can you fix that?
Often, yes. Plenty of our grading work is on homes that have been standing for years. We look at the slope first, then regrade so water drains away from the house, and we will tell you honestly what the fix requires.
