Public sewer

**Public sewer**

A public sewer is a municipal system of underground pipes and infrastructure designed to collect and transport wastewater and stormwater from homes, businesses, and streets to treatment facilities. Unlike private sewer lines that serve individual properties, public sewers are managed and maintained by local government or public utilities to ensure safe and efficient removal of sewage, prevent environmental contamination, and protect public health. Proper functioning of public sewer systems is essential for sanitation, flood control, and sustainable urban development.
