Is Danbury Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Yes, tap water in Danbury, Connecticut, is generally safe to drink. The Danbury Water Department treats and tests its water under Connecticut Department of Public Health and U.S. Environmental Protection Agency standards.
Water quality can vary in older buildings because lead may be present in service lines, plumbing, or fixtures. If concerned about lead, use cold water for drinking and cooking, flush the tap briefly, or use a filter certified to reduce lead.

Source of Water in Danbury, United States
Danbury’s tap water comes primarily from four local surface-water reservoirs: East Lake, West Lake, Kohanza Reservoir, and Margerie Reservoir. These reservoirs collect rainwater and runoff from the surrounding watershed.
The water is treated at the Danbury Water Department’s Miry Brook Water Treatment Plant before entering the city’s distribution system. Treatment removes particles and microorganisms, and the finished water is disinfected to meet Connecticut and federal drinking-water standards.
Danbury Drinking Fountains
Public drinking fountains in Danbury are generally safe to use when they are connected to the public water system and properly maintained. That water is tested and regulated under Connecticut and federal drinking-water standards.
Avoid a fountain that is visibly dirty, damaged, leaking, or marked with a do-not-drink notice. Let the water run briefly before drinking, especially if the fountain has not been used recently.
