Question

Waste water from which source is technically considered gray water, but should be treated as black water?

Washing machine

Shower

Kitchen sink

Toilet

Answer 1

Wastewater from the **kitchen sink** is technically considered gray water, but it should be treated as black water due to the presence of food particles, grease, and potential pathogens. Unlike gray water from sources like a washing machine or shower, which typically contains less harmful contaminants, kitchen sink wastewater can pose greater health risks and is often not suitable for reuse without proper treatment.
