About Us
Information About Your Municipal Water
Groton Utilities is pleased to report that our water supply meets all established Federal and State municipal water standards. Throughout 2017, as in previous years, we received NO violations for water quality. We did receive one infraction for failing to test for chlorine dioxide from September 9-14, 2017; however, we did test for chlorite (a by-product), and results remained consistent with values before and after this period (chlorine dioxide levels ranged from ND to 140 ppb, well under the MCL of 800).
This 20th Annual Water Quality Report contains essential information about your water source, treatment processes, 2017 testing results, and ongoing system improvements. The report also includes guidance on water conservation and protection measures for our valuable resource.
Safety in Our Community, Safety in Our Water
Thank you for reading our 2017 Water Quality Report. This year's theme focuses on Safety—defined as protection against danger, risk, or injury. At Groton Utilities (GU) Water Division, this concept is central to our mission.
Water—the universal solvent—can become contaminated as it moves through the atmosphere, rocks, gravel, and across various landscapes. Our responsibility is to provide safe municipal water through:
- Rigorous source water protection
- Advanced treatment processes
- Comprehensive testing
- Reliable distribution to our valued customers
Our safety commitment extends to our workforce through proper operating conditions and personal protective equipment (PPE). We also maintain appropriate water pressure and storage throughout our service area to ensure fire protection.
As you review this report, we hope you'll recognize our dedication to safety in everything we do.
Thank you!

Source Water Information
Groton Utilities' water comes primarily from a surface water system consisting of five interconnected reservoirs covering a 15.6-mile watershed, supplemented by three wells. The reservoirs—Morgan, Ledyard, Poheganut, Smith Lake, and Poquonnock (terminal reservoir)—have a combined capacity of 2.5 billion gallons when full.
Planning for future needs, in 2014 we secured water rights from Haley's Brook in Groton and worked with local and state agencies to ensure watershed protection status. Our reservoir patrol staff, along with local and state law enforcement, maintain high security levels, monitor for contamination sources, and regularly collect water samples for laboratory analysis. We also maintain a spill response team and equipment to assist with any threats to our water supply.
Protecting our water source is everyone's responsibility. Please report any suspicious activity by calling (860) 446-4000.

The history of Groton Utilities is deeply rooted in the local community – established by the residents of the Borough (now City) of Groton to serve their collective needs. Here's a glimpse into our rich heritage.
Laying the Foundation: Late 1800s
Life in Groton during the late 19th century differed dramatically from today, though many modern conveniences originated then. In 1879, Thomas Edison created the first reliable electric light practical for home use, though it would be decades before Groton Borough homes and streets were wired for electricity.
During the 1890s, municipal water systems became increasingly important, with many larger cities developing public water supply networks. However, few had proper sanitation facilities essential for public health. Fire protection in Groton consisted primarily of bucket brigades and possibly hand pumpers, with no quick access to substantial water volumes during major fires.
Formation of Local Utilities: Early 1900s
To address these critical needs, "Groton Bank" residents invested $100,000 to establish The Groton Water Company followed by The Groton Electric Lighting Company. They acquired land parcels throughout town, including the Poquonnock Bridge area, and constructed a small dam on the Poquonnock Reservoir – tested to be "as pure as spring water" – installing water mains and pumping stations.
1904: Birth of the Borough of Groton
As the region grew, public-spirited citizens (including Charles White, Charles Marquardt, E.A. Card, Arthur Card, Walter Denison, Belton Copp, and Thomas Avery) determined these utilities should belong to the people of Groton. They successfully petitioned the Connecticut legislature to establish "The Borough of Groton," which was officially chartered on May 26, 1904.
With the ability to issue bonds and implement taxation, the Borough raised $150,000 through its first 20-year bonds to purchase the existing water supply and electric distribution facilities. This civic investment allowed for the installation of fire hydrants for volunteer firefighters, the establishment of street lighting circuits, and the wiring of homes for electricity.
