How is a sanitary sewer defined in plumbing systems?

A sanitary sewer is specifically defined as a system designed to carry sewage and wastewater from various sources, such as residential, commercial, and industrial buildings, to a treatment facility or an appropriate disposal location. This system is crucial for maintaining public health and hygiene, as it safely transports waste away from populated areas and prevents contamination of the environment.

The distinction of a sanitary sewer is that it is intended solely for the disposal of human waste and wastewater, thereby ensuring that these substances are handled in a manner that minimizes the risk of disease and environmental impact. In contrast, systems that deal with rainwater runoff, stormwater, or irrigation serve different purposes and are not intended for the transport of sewage. This specialized function makes the sanitary sewer fundamental to modern plumbing systems, contributing significantly to effective waste management and sanitation.
