What is the term for the waterborne wastes derived from ordinary living processes?

The correct term for waterborne wastes derived from ordinary living processes is "domestic sewage." This term encompasses the various types of waste produced by households, including wastewater generated from bathing, cooking, cleaning, and toilet use. Domestic sewage typically contains a mix of water with organic and inorganic materials, and understanding this term is vital for both plumbing and public health perspectives.

Domestic sewage is specifically treated and managed through wastewater treatment systems to prevent environmental contamination and protect public health. While the term "domestic effluent" also refers to waste discharged from residential areas, it is typically used in broader contexts that include treated wastewater, making "domestic sewage" the more precise term for untreated waste directly generated from household activities.

Household runoff generally describes surface water that flows over land from precipitation, which is different from waterborne waste. Wastewater treatment refers to the processes and systems designed to treat water generated from toilets, sinks, showers, and other household activities, but it does not directly describe the waste itself. Therefore, "domestic sewage" is the most appropriate term for waterborne wastes derived from ordinary living processes.
