Our Mission: “Providing High Quality Water to our Customers at Competitive Rates”

HWWEstablished in 1872, the Holyoke Board of Water Commissioners had the vision and foresight to design, plan and build one of the most reliable water systems known today.  A network of reservoirs located within the City of Holyoke and five neighboring communities impound billions of gallons of water ensuring the City’s water supply needs are met under all operating conditions.   Thousands of acres of watershed land owned and operated by Holyoke helps to protect and preserve these resources from contaminants.  An energy efficient gravity based system conveys water from the reservoirs to a centralized treatment facility where it is treated to meet all State and Federal water quality regulations.  Treated water is then distributed to a series of storage tanks and pumping stations that service the five individual pressure zones within the City.

The water that reaches your tap is the result of a multi-step process that includes:

  • Protection – Our sources water protection program focuses on watershed management to maintain the quality of our drinking water sources.
  • Treatment – Our water treatment facility uses liquid chlorine and ammonium to disinfect the water so it is safe to drink.  The water is also fluoridated to reduce tooth decay and prevent cavities.  Finally, additives are introduced to regulate water pH and alkalinity helping to reduce corrosion inside the pipes.
  • Monitoring – We conduct hundreds of tests a year of samples collected from numerous locations throughout the distribution system, the water treatment plant and from the reservoirs.


As a result, the Holyoke Water Works has been able to provide an abundant supply of safe, clean drinking water which is essential to the health and well being of our consumers.  Holyoke Water Works is dedicated to protecting and preserving our valuable water resources for the benefit of the community today and for future generations to come.  Through sound and prudent fiscal practices, we can ensure these services are provided to our community at both affordable and competitive rates.
