Which of the following is a requirement for sewage treatment and disposal systems in North Carolina?

The requirement for sewage treatment and disposal systems in North Carolina involves maintaining a minimum distance from buildings. This distance is crucial for several reasons. It helps prevent contamination of drinking water sources by ensuring that sewage systems do not affect nearby structures or water supplies. Additionally, adequate spacing reduces the risk of structural damage to buildings caused by potential system failures or effluent backflow.

Adhering to these distance requirements is part of the overall regulation to ensure public health and safety while also protecting the environment. The specific minimum distances are typically outlined in local regulations and standards, which must be observed during the installation and maintenance of sewage systems.

While regular maintenance checks, installation of alarm systems, and inspections might also be best practices or recommendations for ensuring the proper functioning of sewage treatment systems, they are not universally mandated as a requirement for the installation itself.
