Which collection system carries household waste?

Which collection system carries household waste?

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

Answer: (A)

Household wastewater is carried by the sanitary sewer. This system collects the used water from toilets, sinks, showers, and laundry from homes and transports it to a wastewater treatment plant. It is separate from stormwater systems, which only carry rain and runoff, and from industrial sewer networks that handle manufacturing waste. Some places historically used a combined system that carries both sanitary waste and stormwater in the same pipes, but that is not the dedicated path for typical household waste. So the option that describes carrying household waste is the sanitary sewer.
