Septic & well regulations in Union County, SC

Union County is located in the Piedmont region of South Carolina. Union County has Piedmont red clay soils (Cecil and Pacolet series) over granite and gneiss bedrock. The Broad River and its tributaries create alluvial corridors with poorly drained bottomland soils. Understanding local permit requirements and soil conditions is essential before installing, repairing, or inspecting a septic system.

Permits & Requirements

New Installation

Site evaluation and septic permit required from SCDES Upstate Regional Office before installation. A licensed installer (Tier 1–3) must be retained for construction. Soil evaluation determines system type per R.61-56 standards. Permit fee is $150 with 5-year validity.

Soil & Terrain Characteristics

Union County has Piedmont red clay soils (Cecil and Pacolet series) over granite and gneiss bedrock. The Broad River and its tributaries create alluvial corridors with poorly drained bottomland soils. Upland soils offer moderate percolation suitable for conventional septic systems.

The Piedmont region is characterized by clay-rich soils that can slow water percolation through drain fields. Professional soil evaluation is essential to determine drain field sizing, as clay content varies significantly even within a single property. Many Piedmont sites require larger drain field areas or modified designs to accommodate slower percolation rates.

County-Specific Considerations

Union County is predominantly rural with limited municipal sewer outside the city of Union. The Sumter National Forest occupies portions of the county, creating protected areas. The Broad River corridor provides recreational opportunities but restricts septic placement near its banks. Population decline has slowed new septic demand but increased the proportion of aging systems needing repair or replacement.
