Water Treatment Plants
MWRA has recently completed two new water treatment plants: The John J. Carroll Water Treatment Plant, in Marlborough (2005) and The Quabbin Water Treatment Plant, in Ludlow (2000).
Both facilities improve finished water quality and comply with state and federal drinking water standards.
John J. Carroll Water Treatment Plant, Marlborough
The John J. Carroll Treatment Plant treats drinking water for the majority of MWRA customers: residents and businesses in MetroWest and Metro Boston communities (>list of communities)
The John J. Carroll Plant uses ozone as a primary disinfectant and chloramines for residual disinfection, allowing MWRA to meet current and tougher future state and federal water quality standards. The plant has the capacity to treat up to 405 million gallons of water from the Wachusett Reservoir each day, though 270 million gallons per day is the average.
The Quabbin Water Treatment Plant, Ludlow
This plant treats drinking water for three Chicopee Valley communities: Chicopee, Wilbraham and South Hadley Fire District #1.
Water enters this plant directly from the pristine Quabbin Reservoir. It is treated with chlorine, for primary disinfection in accordance with the federal Safe Drinking Water Act.
