A soil wetness condition determined by observation or indication of lateral water movement within 48 inches of the naturally occurring soil surface shall be considered what?

Understanding soil drainage is crucial for a septic system’s effectiveness. If you observe wetness or see water moving laterally within 48 inches of the natural soil surface, the soil is effectively saturated and drains poorly. A drainage system needs soil that can accept effluent and allow it to infiltrate downward without sustained surface or near-surface saturation. When lateral water movement is that close to the surface, the soil cannot meet those requirements, so it’s considered unsuitable for a conventional septic absorption area.
