Storm sewers are underground systems designed to manage rainwater and melted snow. They collect excess water from streets, parking lots, and other surfaces to prevent flooding. The water flows through a network of pipes and drains, directing it to nearby rivers, lakes, or treatment facilities. These systems are essential for urban areas, where large amounts of impermeable surfaces can lead to rapid water accumulation. By efficiently channeling stormwater, storm sewers help protect property and infrastructure from water damage and reduce the risk of pollution entering natural water bodies.
