What system is designed to convey stormwater runoff and other drainage?

The system designed specifically to convey stormwater runoff and other drainage is indeed the storm sewers. Storm sewers are engineered to collect and transport rainwater and melted snow from urban areas, streets, and other surfaces to prevent flooding and manage stormwater effectively. This system is critical for maintaining public safety and infrastructure integrity during heavy rainfall events.

Storm sewers typically lead directly to natural water bodies or treatment facilities, ensuring that excess water does not accumulate and cause damage. This design is essential for managing stormwater in a way that helps mitigate erosion, protect local ecosystems, and reduce the risk of combined sewer overflow situations.

The other systems have different primary functions; combined sewers handle both wastewater and stormwater in a single system, sanitary sewers are solely for carrying wastewater from homes and businesses, and stormwater mitigation systems involve various techniques to manage and treat stormwater but are not the primary conveyance system.
