What is the wastewater from a water closet commonly referred to as?

• A. Grey water
• B. Black water
• C. Clean water
• D. Storm water

Answer: (B)

The wastewater from a water closet, commonly known as a toilet, is referred to as black water. This term specifically denotes wastewater that contains human waste and other organic materials, making it distinct from other types of wastewater. In residential and commercial settings, black water is characterized by its high potential for contamination, requiring particular handling, treatment, and disposal methods to ensure that public health and environmental safety are maintained. In contrast, grey water refers to wastewater from sinks, showers, and appliances that does not contain significant amounts of human waste. Clean water is typically treated water that is safe for drinking and other uses, while storm water pertains to runoff from rainy weather, which may carry pollutants but does not directly relate to toilet waste. Understanding these definitions is crucial for proper wastewater management and sanitation practices.
