A body waste holding tank that receives discharge from any toilet is called a _____________.

The term for a body waste holding tank that receives discharge from any toilet is specifically a "Black Water Holding Tank." This designation is used because black water refers to wastewater collected from toilets, which typically contains solid human waste and is distinct from other types of wastewater. Understanding this distinction is critical for proper RV maintenance and sanitation practices.

Fresh water tanks, on the other hand, are designed to store potable water for drinking and other uses. Grey water tanks collect wastewater from sinks, showers, and washing machines, which do not contain human waste but may still require proper disposal due to contamination. Liquid waste holding tanks is a more general term that does not specifically refer to the waste collected from toilets and could encompass various types of waste liquids.

Thus, being familiar with these definitions helps RV technicians correctly identify and manage the different types of holding tanks in an RV to ensure health, safety, and compliance with local regulations.
