Aquarion Water acquires Ansonia wastewater system in largest New England deal

Aquarion Water Company has officially completed the acquisition of the City of Ansonia’s municipal wastewater system, a landmark transaction marking the largest privatization of such a system in New England. This pivotal wastewater system acquisition, valued at $41 million, underscores a significant shift in New England infrastructure management. Aquarion has also committed to investing $15 million in infrastructure improvements within the next five years.

Aquarion’s president, Donald Morrissey, emphasized the company’s enthusiasm in welcoming Ansonia residents and businesses to their portfolio, expressing a long-term commitment to customer service and environmental stewardship. He noted that the acquisition aligns with Aquarion’s broader strategy of consolidating municipal wastewater systems across the region.

Ansonia Mayor David Cassetti framed the sale of the Ansonia wastewater system as a pivotal step in the city’s broader revitalization efforts. He highlighted that the transaction will allow Ansonia to prioritize core areas like public safety, education, and economic development while ensuring stable sewer and tax rates for years to come.

The Ansonia wastewater system, which serves 5,800 customer connections, expands Aquarion Water Company’s footprint in Connecticut. The company already provides water services to neighboring communities such as Derby, Seymour, and Shelton. This acquisition is part of a larger trend for Aquarion, which has integrated 91 water and wastewater system acquisitions since 2011. Notable transactions include municipal systems in Derby and towns such as New Hartford.

Under Aquarion’s ownership, customers of the municipal wastewater system will gain access to enhanced conveniences, including expanded options for bill payment. Customers can now pay online, by phone, through mail, or in person at designated payment locations.

As the largest privately-owned water utility in New England and a subsidiary of Eversource, Aquarion Water Company serves over 780,000 residents across 73 municipalities in Connecticut, Massachusetts, and New Hampshire. Founded in 1857, the company continues to emphasize sustainable practices and environmental responsibility while expanding its influence in New England infrastructure.
