About Marion County — What Affects Your Septic System

Water Table

Marion County Water Table and Septic Considerations

On the sandy loam uplands of Marion County, the seasonal high water table generally sits 3 to 5 feet below the surface, allowing adequate separation for conventional septic systems. In the extensive bottomlands along the Great Pee Dee and Little Pee Dee rivers, the water table frequently rises to within 12 inches of the surface or higher during the winter and spring wet season. The Lumber River also joins the Little Pee Dee near Nichols, adding to the volume of water that saturates the low-lying portions of the county and limits septic options in those areas.

Local Statistics

Marion County by the Numbers

Marion County has a population of approximately 28,900 residents with roughly 14,300 housing units across 489 square miles. As a predominantly rural county, a large share of homes — likely 50% or more — use septic systems rather than municipal sewer, with sewer service concentrated in the towns of Marion and Mullins. Rural lot sizes are generous, often ranging from one to five acres or more.

Soil Composition

Marion County Soil Types and Septic Performance

Marion County's upland soils are predominantly sandy loam of the Norfolk and Orangeburg series, which are well drained with moderate permeability and generally suitable for conventional septic drain fields. However, the county is flanked by the Great Pee Dee River on the west and the Little Pee Dee River on the east, and the wide river bottomlands between them contain poorly drained alluvial soils with high clay and organic content. These floodplain soils drain very slowly and typically cannot support conventional septic systems, requiring mound systems or connection to public sewer where available.

Seasonal Tips

River Flooding and Septic Care in Marion County

The Pee Dee River system that borders Marion County is prone to extended flooding after hurricanes and heavy rainfall events, with floodwaters sometimes remaining for weeks. If your property is in or near the floodplain, reduce water use dramatically during high-water events and avoid flushing anything other than waste and toilet paper. After floodwaters recede, wait for the soil to dry before scheduling a pump-out, and have the tank inspected for silt infiltration.
