Which collection system handles all 'non-human waste' (excluding rainwater)?

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

Answer: (B)

Non-human wastewater comes from industrial processes, not from people’s homes. An industrial sewer system is designed to collect that kind of wastewater—the non-human, process-related effluent from factories, plants, and similar facilities. Rainwater is excluded in this question, so stormwater systems aren’t involved. Sanitary sewers carry domestic wastewater that includes human waste, while a combined system collects both sanitary and stormwater in one pipe. So, for handling non-human process waste, the industrial sewer is the appropriate choice.
