About Us
The Holyoke Water Works (HWW) is pleased to present its 2017 Annual Water Program Report. This report aims to inform residents about the high-quality water and services we provide daily. Our team is dedicated to safeguarding and preserving local water resources. In 2017, your water successfully met all Federal and State water quality standards, with detailed results available on pages 2-3 of this report.
If you have questions about water quality, please contact Butch Seidel, Reservoir Division Supervisor at (413) 532-6778. For billing inquiries, call our main office at (413) 536-0442. Additional information is available at the Holyoke Board of Water Commissioners' monthly public meetings, with dates posted at Town Hall and on the City's website (www.holyoke.org).
Holyoke's water primarily comes from the Tighe-Carmody Reservoir in Southampton via a 6.6-mile Pre-stressed Concrete Cylinder Pipe built in 1997. Supply is supplemented by the McLean Reservoir through a transfer pump station in the Ashley Reservoir watershed. Blending these sources ensures optimal water quality year-round.
Our water undergoes treatment at the Water Treatment Facility at 600 Westfield Street near McLean Reservoir. In 2017, HWW continued efforts to reduce trihalomethanes and haloacetic acids formation through controlled blending. We combined 80,669,500 gallons (4.93%) from McLean Reservoir with other sources to meet the city's annual demand of 1,635,415,000 gallons. With these measures, Holyoke maintains an unfiltered status in Massachusetts along with MWRA, Northfield, and Concord.
In 2017, Tighe & Bond conducted an inspection of our Risk Management Plan, identifying needed updates to signage, alarms, and treatment equipment. HWW promptly implemented these improvements to maintain full compliance with EPA safety requirements for facilities storing hazardous chemicals like gaseous chlorine.
The Holyoke Water Works has developed Forest Stewardship Council Green Certification Management Programs for its reservoir properties. These programs help protect water quality through selective harvesting that creates diverse, all-aged forests serving as natural filtration systems. Our watershed management approach reflects globally approved standards for resource protection and sustainable forestry practices.
Our Watershed Resource Protection Plan (WRPP) identifies potential threats to water supplies, implements protective measures, and develops strategies against future risks. The plan includes Forest Management guidelines to maintain forest cover, preserve water quality, prevent erosion, and reduce fire hazards. For WRPP questions or to learn how you can help protect our watershed, contact Butch Seidel at (413) 532-6778.

Holyoke holds the distinction of being the first planned industrial community in the United States. The downtown area features distinctive rectilinear street networks, unusual in New England architecture. In 1847, merchant investors utilized a natural 57-foot drop in the river to construct an innovative stone dam and canal system. This development sparked the creation of an extensive complex of factories and worker housing.
The thoughtful street hierarchy supporting both industrial buildings and residential areas was designed as an economic development tool. The layout accommodates taller structures, while the surrounding waterways were transformed into recreational spaces. Holyoke attracted successive waves of immigrants—Irish, French Canadian, German, Polish, Jewish, and Italian—who worked in the mills, established small businesses, and built community.
The population surged from approximately 5,000 in 1860 to over 60,000 by 1920, prompting official incorporation as a city on April 7, 1873, just 23 years after its initial establishment as the "Town of Holyoke." The city's primary industry was paper manufacturing, earning Holyoke the nickname "Paper City" as it became the world's largest paper-producing center—a moniker that persists today.
The Wistariahurst Museum on Cabot Street preserves Holyoke's rich history. Originally home to prominent silk manufacturer William Skinner and family, the museum now offers diverse educational programs, workshops, exhibits, lectures and performances that enhance community life. The History Room at Holyoke Public Library maintains valuable collections including maps, photographs, city directories, and newspaper archives (on microfilm) dating from the 1850s through the 1990s.
