urban drainage systems

Urban drainage systems are networks of pipes, channels, and storage areas designed to manage rainwater and runoff in cities. They collect excess water from streets, roofs, and other surfaces to prevent flooding and water damage. The system often includes storm drains, underground pipes, detention basins, and pumps that direct water safely away from urban areas into natural water bodies or treatment facilities. Proper design ensures efficient water flow, reduces flooding risk, and helps protect public health and the environment by controlling pollutants carried with the runoff.
