Stormwater drainage systems are designed to manage excess rainwater and prevent flooding in urban areas. These systems typically include components like drainage pipes, catch basins, and stormwater ponds that collect and direct water away from streets and buildings. By channeling stormwater, these systems help protect infrastructure and reduce erosion. Properly functioning stormwater drainage systems also play a crucial role in maintaining water quality. They can filter pollutants from rainwater before it enters natural bodies of water, such as rivers and lakes. This helps to preserve local ecosystems and ensures cleaner water for both wildlife and human use.
