What is the primary function of a storm sewer?

The primary function of a storm sewer is to convey rain and surface water. Storm sewers are designed specifically to manage excess water from precipitation, such as rain or melting snow, directing it away from urban areas, streets, and other developed land to prevent flooding and water accumulation. This system collects runoff and channels it through drainage systems to prevent water from pooling in areas where it could cause damage or disrupt daily activities.

In contrast, other options are designed for different purposes. Removing sewage from buildings is the role of sanitary sewers, which focus on carrying wastewater from residential and commercial properties. Conducting drinking water falls under the responsibilities of potable water supply systems, ensuring that safe and clean water is delivered to consumers. Handling industrial waste involves specialized treatment and disposal systems tailored for managing byproducts from industrial processes. Each of these functions is crucial but serves a different aspect of public health and infrastructure.
