Soil & Terrain Characteristics
Tyrrell County, the least populated county in NC, has extremely flat terrain with organic soils and water tables often within inches of the surface. Vast pocosins and swampland dominate the landscape, and even agricultural areas sit on poorly drained soils. Conventional septic systems are impractical for virtually every property, requiring advanced treatment technologies for all installations.
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
Advanced treatment systems are required for virtually every installation due to the extremely high water table and organic soils. The remote and sparsely populated character of the county limits contractor availability.
Well Construction Standards in Tyrrell County
Private wells in Tyrrell 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
