What is the minimum horizontal distance between any building foundation and a sanitary sewage system?

The minimum horizontal distance between any building foundation and a sanitary sewage system is established to ensure the safety and effectiveness of both the building's structural integrity and the sewage system's function. In North Carolina, this minimum distance is set at 5 feet based on health regulations and building codes. Maintaining this distance is crucial because it prevents potential contamination of the building’s groundwater supply from the sewage system, reduces the risk of damage to the septic system from the building's weight, and allows for proper maintenance and access to the sewage system.

A margin greater than this minimum, while sometimes advised for specific situations or soil types, is not mandated as the minimum requirement under standard regulations, thus affirming that 5 feet is the legally acceptable minimum separation for safety and structural considerations.
