Water Supply

The Water Supply program regulates permanently installed systems providing piped water to the public for drinking and other potable purposes. All such systems with at least five service connections used year-round must obtain a Water Supply Permit from DEC before undertaking any of the published regulated activities (e.g. expanding or interconnecting systems). This program protects and conserves available water supplies by ensuring equitable and wise use so that the state’s waters can satisfy domestic, municipal, agricultural, commercial, industrial, power and recreational needs and other beneficial public purposes.
