Hyannis Water Announces a $12 Million Upgrade to Water System

New water filtration building...

The Hyannis Water System announces the construction of a new water filtration building at the Maher Water Treatment Plant.  The $12 million upgrade to the water system was recommended in the 2016 final conceptual design report and confirmed in the 2017 pilot test report. In addition to meeting new stricter federal and state regulations for the emerging contaminants PFAS and 1,4-Dioxane, the project will remove manganese and iron.

After much study the Hyannis Water Board recommended the construction of a new water filtration building near the Maher treatment plant. The Hyannis Water Board was created to provide citizen input and oversight for the Water Supply Division of the Department of Public Works. Mr. Stephen O’Neil, Chair of the Hyannis Water Board said “Our water system is over 100 years old and has serious capital needs we have been diligently addressing. The construction of this state of the art filtration plant will be a pro-active investment in the future of the Hyannis Water System”

Mr. Daniel Santos, Director of Public Works, Town of Barnstable said “this project will allow the Hyannis Water system to continue to provide adequate supplies of drinking water  to businesses, residents, and tourist that meets all federal and state standards.”

The water filtration building at the Maher Treatment Plant has a design capacity of 1,500 gallons per minute. The plant will remove PFAS with activated carbon filtration, 1,4-Dioxane by advanced oxidation with peroxide and ultraviolet light (UV) and remove iron and manganese by greensand filtration. Construction of the Maher water filtration plant will begin immediately and follow an accelerated schedule.  The water filtration plant is expected to be operational by the fall of 2021.

Contractors for the project include Tata & Howard, providing engineering services; and Waterline Industries Corporation will construct the filtration building.

Financing for the water filtration project is provided by borrowing from the Massachusetts Department of Environment Protection’ State Revolving Fund (SRF) with principal forgiveness resulting in a lower interest rate to minimize financial impacts to the rate payers.

The Hyannis Water System consists of four water treatment facilities, four storage tanks, 12 well pumping stations, and 107 miles of distribution system. The water system provides drinking water services to about 18,000 residents through 7,249 metered service connections to residential and commercial properties. Supplying its drinking water from ground sources, the Hyannis Water System draws about 2.77 million gallons per day (MGD) from wells with an annual production of 902 million gallons.
