The story

Connecticut Water Service had been incorporated on February 1, 1956. It had been traded on NASDAQ under the ticker CTWS.

In October 2018, it was announced that Connecticut Water Service was being acquired by the SJW Group, a water utility company based in San Jose, California, pending federal approval.

Eversource Energy, an electric and gas utility serving most of New England (including areas served by Connecticut Water's Connecticut systems), submitted a rival bid, but was turned down by the board of Connecticut Water.

The SJW Group had earlier formed Hydro Sub, Inc. to conduct the acquisition. It was dissolved on 9 October 2019 following the completion of the merger.
