What is the minimum horizontal distance required between a sanitary sewage system and any swimming pool?

The minimum horizontal distance required between a sanitary sewage system and any swimming pool is indeed 15 feet from the water's edge. This distance is established to protect public health and safety, as it minimizes the risk of contamination from sewage systems to swimming areas. Inadequate separation could lead to potential hazards, including the introduction of pathogens and pollutants into the pool, which could pose health risks to swimmers.

This specific distance ensures that any potential leaks or issues with the sewage system do not have a direct pathway to the pool area. It is essential for inspectors to be aware of such regulations to ensure proper installation and maintenance of sewage systems in relation to recreational water facilities.

Other distances provided in the choices, such as 10 feet, 20 feet, and 25 feet, do not align with standard regulations established for protecting water quality and public health within North Carolina. Maintaining the correct minimum distance is critical for compliance with legal and safety standards in septic system management and swimming pool operation.
