A sanitary sewer is specifically defined as a conveyance system designed to transport domestic wastewater away from homes, businesses, and other facilities for treatment and disposal. This definition highlights its primary purpose of handling sewage and wastewater generated from household activities such as bathing, cooking, and flushing toilets.

The characteristics of sanitary sewers differentiate them from other types of sewer systems. For instance, stormwater management systems are designed to handle rainwater and prevent flooding, and drainage systems for industrial waste cater to unique needs associated with the disposal of industrial byproducts. Similarly, systems for outdoor water runoff manage excess surface water rather than treating or transporting sewage. The clarity of function is critical in plumbing and environmental safety, ensuring that wastewater is handled appropriately to maintain public health and comply with local regulations.
