BRIDGEPORT — Aquarion Water Co. has announced a deal to acquire a small, private water system in New Fairfield.

Terms of the utility’s deal to purchase the Dunham Pond Condominiums water system were not released. The system serves about 108 New Fairfield residents, Aquarion officials said Wednesday.

The deal is the fourth the company has made this spring to acquire privately owned water systems in Fairfield County. It previously acquired the Oakwood Acres and Fieldstone Ridge systems from Rural Water Co. and the Birches and Possum Ridge systems from Black Systems.

Aquarion already owned the Ball Pond water system and with this spring’s acquisitions, including the Dunham Pond deal, the utility now provides water service to about 1,500 residents in New Fairfield .

All of the deals must be approved by the state Department of Public Health, as well as the state Department of Public Utility Control.

The deals are part of an effort to consolidate small water utilities in the Danbury area and provide “a cohesive, long-term water solution to address future development in these communities,” said Charles Firlotte, Aquarion’s president and chief executive officer.

Aquarion provides water for more than 580,000 people in 39 communities in Connecticut, as well as serving customers in Massachusetts and New Hampshire.
