What is the term used for water that is safe for drinking?

The term used for water that is safe for drinking is "Palatable Water." This designation indicates that the water not only meets safety standards for human consumption but is also agreeable in taste, odor, and appearance.

Gray water refers to wastewater generated from household activities such as laundry and dishwashing that can be reused for irrigation or flushing toilets, but it is not safe to drink. Pests are typically insects or animals that might pose a threat to health or hygiene, and they have no relation to the classification of water. Black water includes wastewater that comes from toilets, containing pathogens and other harmful substances, making it unsafe for human consumption. Therefore, palatable water is the correct term for water that is suitable for drinking.
