Septic & well regulations in Greene County, NC
Greene County is located in the Coastal Plain region of North Carolina.

Understanding local permit requirements and soil conditions is essential before installing, repairing, or inspecting a septic system.

Soil & Terrain Characteristics
Greene County has flat coastal plain terrain with loamy soils that provide generally adequate drainage for conventional septic systems. However, low-lying areas near Contentnea Creek and its tributaries have seasonally high water tables that can reach the drain field zone. Upland sites typically have sandy loam over clay subsoil with moderate percolation rates.
The Coastal Plain features flat terrain with naturally high water tables that create challenges for conventional septic systems. Many properties require advanced treatment systems, mound systems, or other alternatives designed to function where groundwater is close to the surface. Seasonal flooding and storm surge can also affect system performance in low-lying areas.
County-Specific Considerations
Properties near Contentnea Creek should be evaluated for seasonal water table fluctuations before system design. Well water testing for agricultural contaminants is advisable given the county's farming intensity.
Well Construction Standards in Greene County
Private wells in Greene County must meet North Carolina well construction standards under 15A NCAC 02C. These requirements apply to all new domestic and irrigation wells.
Casing Height Requirements
Well casing must extend at least 12 inches above the finished grade around the well. This prevents surface water from entering the well during rain or minor flooding events.
Concrete Pad & Well Cover
A concrete pad or slab is required around the well casing to prevent surface water infiltration. The well must have a sanitary seal or cap that meets NC DEQ standards.
Casing Materials & Depth
Approved casing materials include steel, PVC, and stainless steel. Bedrock wells require casing to extend at least 20 feet into competent rock. A 6-inch diameter is standard for residential wells.
Setback Distances
Wells must be at least 50 feet from septic tanks, 100 feet from drain fields and soil absorption systems, and 100 feet from animal waste areas. Contact Greene County Environmental Health for county-specific setback requirements.
