The Biddeford and Saco Water Co. said it would be acquired by Connecticut Water Services Inc., giving the Maine water services company greater access to funds to make infrastructure improvements.

The deal with Connecticut Water Services, based in Clinton, Conn., is expected to close in the fourth quarter of 2012. The terms of the deal were not disclosed.

Biddeford and Saco Water customers should not be disrupted by the deal, the company said. As a result of the proposed transaction, the rate increase application for Biddeford and Saco Water that was originally planned for 2012 will now be delayed until at least 2013, the company said.

When the transaction is complete, Biddeford and Saco and Maine Water will service more than 30,000 customers in 21 communities in Maine.

“As part of CTWS, our customers will continue to be served by the same Biddeford and Saco employees and our office and existing facilities will be retained,” Jerry Mansfield, president of Biddeford and Saco Water said.

Over time, the companies said there would be opportunities to share staff, systems and services between the two Maine firms. Additional details were not disclosed.
