What type of pipe system receives rainwater for disposal into a waterway?

• A. Storm sewer
• B. Subsoil drainage pipe
• C. Combined sewer
• D. Sanitary building drain

Answer: (A)

A storm sewer system is specifically designed to collect and transport rainwater or surface runoff to prevent flooding and manage water drainage. The primary function of storm sewers is to direct rainwater efficiently into nearby waterways, such as rivers or lakes, or to designated drainage areas. This system typically does not handle wastewater from homes or businesses, which differentiates it from combined sewers and sanitary drains. Combined sewers handle both stormwater and wastewater together, which can lead to issues during heavy rainfall where the capacity may be exceeded. Sanitary building drains are designed for the removal of wastewater from toilets, sinks, and other plumbing fixtures, while subsoil drainage pipes are used mainly for groundwater management rather than surface water like rain. Therefore, the storm sewer is the most appropriate choice for managing rainwater runoff specifically.
