What is the primary distinction between sanitary and storm sewers?

The primary distinction between sanitary and storm sewers lies in their intended purposes and the types of water they transport. Sanitary sewers are specifically designed to convey wastewater generated from residential, commercial, and industrial sources, including sewage and effluent from bathrooms, kitchens, and other plumbing fixtures. This wastewater is typically treated before being released into the environment.

On the other hand, storm sewers are constructed to handle rainwater and surface runoff. This includes water that accumulates on the ground during rainfall or as a result of melting snow. Storm sewers are crucial for preventing flooding and ensuring that excess water is drained away from urban areas quickly and efficiently.

Understanding this distinction is important for anyone involved in plumbing or municipal water management, as it informs how systems are designed, maintained, and regulated to protect public health and the environment.
