What is a TNC?

A transient non-community (TNC) system is any publicly or privately owned establishment that has its own drinking water source(s), provides water for human consumption, and serves 25 or more people per day at least 60 days per year. The persons served need not be the same people. Some examples of businesses that are commonly TNCs are listed below. Many TNCs are the small businesses that help make Vermont unique and that are the mainstay of the state’s tourism industry. The WSD regulates about 700 TNCs.

Water for human consumption includes that used for drinking, bathing, showering, cooking, dishwashing, and maintaining oral hygiene and other sanitary functions in which the public has access to the water. Some examples at TNCs include water used in bubblers, coffee makers, post mixed beverage machines, restroom facilities, and that used to make ice, foodstuffs, or other products for human consumption.
