Which type of water is defined as wastewater from non-latrine sources?

Gray water is defined as wastewater generated from non-latrine sources, such as sinks, showers, washing machines, and dishwashers. This type of water typically contains fewer pathogens and is less contaminated than black water, which comes from toilets and contains human waste.

Understanding gray water is important because it can potentially be reused for irrigation or other purposes, depending on local regulations and treatment processes. This characteristic makes it a valuable resource in water-scarce regions or in situations where conservation is critical.

The other options focus on different categories of water: black water is heavily contaminated and contains fecal matter, raw water refers to untreated water from natural sources, and non-potable water is water that is not safe for drinking, which can include both gray and black water as well as other sources. These definitions highlight the distinct nature of gray water and its utility in water management practices.
