The term that describes wastewater generated from sources other than toilets is gray water. Gray water typically comes from sinks, showers, bathtubs, and washing machines. It is distinct from black water, which refers specifically to wastewater that contains human waste and is generated from toilets. Gray water can often be reused for purposes such as irrigation or toilet flushing after proper treatment, making it a valuable resource in water conservation efforts.

Stormwater refers to precipitation that flows over surfaces and can carry pollutants but does not originate from household wastewater sources. Sewage is a broader term that includes all types of wastewater, including both gray water and black water. By understanding these definitions, one can appreciate the role and potential reuse of gray water compared to other classifications of wastewater.
