On Wednesday, August 7, 2019, the Hyannis Water System and officials from MassDEP held a ceremonial groundbreaking for construction of the new Maher Water Treatment Plant designed by Tata & Howard, Inc.
The $12 million water system upgrade, funded by the MassDEP SRF program, will enable the Town to meet new and stricter federal and state regulations for emerging contaminants. The new plant will treat elevated levels of Perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), 1,4-Dioxane, iron, and manganese in the three drinking water production wells at the existing facility.
The water filtration building at the Maher Water Treatment Plant has a design capacity of 1,500 gallons per minute. Using granular activated carbon filtration, the successful removal of PFOS/PFOA will be obtained. Advanced oxidation with peroxide and ultraviolent (UV) light will treat 1,4-Dioxane. Lastly, greensand pressure filtration will not only remove the iron and manganese, but also extend the useful life of the granular activated carbon.
Tata & Howard has been instrumental in the evolution of this project. In December of 2016, Tata & Howard provided a conceptual design report to Barnstable’s Department of Public Works. A pilot test report was submitted in early 2018 and design began shortly thereafter.
The Hyannis Water System currently consists of four water treatment facilities, four storage tanks, 12 well pumping stations, and a 107-mile distribution system. The water system provides drinking water services to approximately 18,000 residents through 7,249 metered service connections to residential and commercial properties.
Waterline Industries Corporation of Seabrook, NH constructed the filtration building, and Tata & Howard provided construction administration and resident observation. The facility was operational in October 2020.
