Conn. Gen. Stat. § 25-33c

The General Assembly finds that an adequate supply of potable water for domestic, commercial and industrial use is vital to the health and well-being of the people of the state. Readily available water for use in public water systems is limited and should be developed with a minimum of loss and waste. In order to maximize efficient and effective development of the state's public water supply systems and to promote public health, safety and welfare, the Department of Public Health shall administer a procedure to coordinate the planning of public water supply systems.
