A storm drain is a system designed to manage excess rainwater and prevent flooding in urban areas. It collects rainwater from streets, parking lots, and other surfaces, directing it into underground pipes or channels. This helps to keep roadways clear and reduces the risk of water damage to buildings and infrastructure. Storm drains often have grates or openings that allow water to flow in while keeping out larger debris. They are an essential part of urban planning and are connected to larger systems, such as sewers or retention ponds, to ensure proper drainage and environmental protection.
