About Us
The following report satisfies the Federal Safe Drinking Water Act (SDWA) requirement for community water utilities to provide annual water quality information to customers. This report covers 2017 but includes relevant data from other years. All test results are from independent certified laboratories.
This annual report helps inform Wellesley residents about their water sources, quality, and the decision-making processes affecting their water supply. Public participation opportunities are available at monthly Board of Public Works meetings. For more information, contact Water Superintendent Bill Shaughnessy at 781-235-7600 x 3350, located at 20 Municipal Way.
The MWRA (Massachusetts Water Resources Authority) is our regional utility that manages surface water supplies from the Quabbin and Wachusett Reservoirs and Ware River in central Massachusetts. Their water quality report is included as the final page of this document and available on their website. When reviewing water quality data, please note that the mixture of MWRA and local waters creates some variations between water sources.
Our diverse water supply sources ensure reliable service to meet community needs. In addition to our active sources, Wellesley's water distribution system connects with four neighboring suppliers (Natick, Needham, Weston, and Wellesley College) for emergency preparedness.
The Massachusetts Department of Environmental Protection has completed its Source Water Assessment Program (SWAP) Report for all Wellesley's local water sources. This report helps focus protection efforts on appropriate management practices for our water sources, which like most suburban locations, have high susceptibility ratings.
Our distribution system includes approximately 140 miles of street mains and two large storage facilities with nearly six million gallons capacity. Due to the system's configuration, water from any supply source can reach virtually any point within town.
Wellesley operates three water treatment facilities providing corrosion control under the Safe Drinking Water Act's Lead and Copper Rule. These facilities apply the same treatment processes to all wells. The treatment includes oxidation and pH adjustment before filtration, which removes naturally occurring iron and manganese minerals. The filters contain anthracite, green sand, and garnet sand. After filtration, water passes through tray aerators to remove naturally occurring carbon dioxide, reducing acidity. The water is then fluoridated and disinfected with hypochlorite before storage and distribution.

Over 350 years ago, when settlers first established themselves along the Charles River in what is now Wellesley, they were so charmed by their surroundings that they named the area "Contentment." Though the name evolved over centuries, residents' pride in their community remains steadfast today.
The 1981 Centennial Celebration marked a pivotal moment for many residents - a year-long exploration of Wellesley that renewed appreciation for its history, strengthened pride in its present, and reinforced commitment to its future. Through historical books, multimedia presentations, time capsules, theatrical recreations featuring elected officials as founding fathers, town gatherings, and educational programs, Wellesley spent a year reconnecting with its heritage.
Historical records show that in the 1630s, following negotiations with Chiefs Nehoiden and Maugus (whose names still appear throughout town), nineteen pioneer families purchased the land that would become Wellesley for five pounds of currency and three pounds of corn. Initially part of Dedham, population growth led to the creation of Needham, with the western portion later becoming Wellesley.
The quiet farming community of West Needham saw its residents join neighbors in pivotal American conflicts, from the Revolutionary War's first battles at Concord in 1775 to Gettysburg nearly a century later. The 1830s brought railway connections that forever changed the tranquil town by making it accessible to Boston businesspeople seeking pastoral surroundings.
Henry Durant significantly impacted the area in 1875 by establishing Wellesley College, now one of America's most prestigious women's universities, on its scenic lakeside campus. He named the college to honor his neighbor Horatio Hollis Hunnewell, a wealthy businessman whose estate was called "Wellesley" after his wife's maiden name, Welles.
By 1880, modernization was rapidly transforming the community with newspapers, banks, telephones, new churches and homes. Led by Durant, Hunnewell and politician Joseph Fiske, residents organized to separate from Needham. After intense campaigning and heated town hall debates, Wellesley officially became an independent town on April 6, 1881, named as a tribute to Hunnewell's contributions.
