What defines a public sewerage system?

A public sewerage system is characterized primarily by being a municipal system that is designed for the collection and treatment of sewage from a community or city. Such systems are typically managed and maintained by local government entities, ensuring that wastewater is adequately treated and disposed of in a manner that protects public health and the environment.

Municipal systems are generally extensive, covering large areas and serving numerous households, which aligns with the definition of a public service that provides essential infrastructure for waste management.

While other systems may involve private companies or be applicable to numerous households, these do not meet the specific public designation or the operational mandate of governmental oversight that defines a public sewerage system. Moreover, the mention of gravity-based systems does not capture the broader spectrum of technologies and methods that a public sewer system may employ, as these systems can also include pumped systems where necessary due to terrain or other factors.
