Customers of Aquarion Water Co. should reap the benefits in their monthly bill from a $29 million settlement reached between the state and water utility related to a change in the Internal Revenue Service’s accounting regulations.

Aquarion stands to recover about $29 million for taxes paid since 2007 and, as part of a settlement agreement, the company will refund those dollars to its customers over a three-year period, Consumer Counsel Elin Swanson Katz and Attorney General George Jepsen recently announced.
