Storm drains: essential infrastructure for flood

Storm drains are an essential component of urban water management, designed to collect and convey rainwater quickly to prevent pooling on roads and properties. In cities and towns, a well-planned network helps minimize flooding, protect infrastructure, and reduce health and safety risks associated with standing water.


Why they matter

During heavy downpours, rainfall can overwhelm surface drainage. Storm drain systems, including catch basins, underground pipes, and outfalls, are engineered to handle peak flows and prevent rapid water accumulation that can threaten homes, businesses, and critical services.

How they work


Most systems use gravity to move water from residential areas to larger channels, rivers, or into controlled discharge points. Regular maintenance—clearing debris, inspecting grates, and repairing pipes—keeps flow unobstructed and reduces the risk of blockages that can cause localized flooding.
