Which collection system carries surface runoff to a desired location, often a catch basin and then to receiving waters?

Which collection system carries surface runoff to a desired location, often a catch basin and then to receiving waters?

• A. Sanitary
• B. Storm
• C. Industrial
• D. Combined

Answer: (B)

Surface runoff from rain or melted snow needs a dedicated path, so a stormwater collection system is built to capture that runoff and move it to a receiving body of water. It uses inlets and catch basins to collect water, then carries it through storm sewers to streams, rivers, or other outlets. This is different from sanitary systems, which are designed to carry domestic wastewater from homes and businesses; industrial systems, which handle process waste from manufacturing; and combined systems, which carry both stormwater and wastewater in the same pipes (and can overflow during heavy rain). The description—carrying surface runoff to a catch basin and then to receiving waters—fits the stormwater system best.
