Question

Wastewater from which source is technically considered graywater, but should be treated as blackwater?

kitchen sink
toilet
shower
washing machine

Answer 1

The wastewater from a **kitchen sink** is technically considered graywater, but it should be treated as blackwater due to the presence of organic material, food particles, and potential pathogens. While graywater typically includes wastewater from sinks, showers, and washing machines (excluding toilet waste), the contaminants found in kitchen sink wastewater warrant more stringent treatment.
