Our History

The City of Groton is a residential community which developed on the east bank of the Thames River, locally called the “Groton Bank”. It became the Borough of Groton by an act of the legislature at the turn of the 20th century. The charter creating a new government provided for a Department of Utilities. The proceeds of a bond sale by the Borough were used to purchase the Groton Electric Lighting Company, established in the early 1890s to provide lighting for the main streets of the Groton Bank, and Groton Water Company, also established in the early 1890s to supply water to Groton and a large New York, New Haven, and Hartford railroad facility located in the Poquonnock Bridge area.
