The Town of Winchester’s middle-low system will be switching over to Massachusetts Water Resource Authority (MWRA) water supply during a reservoir construction project from March 2 through May 15, 2016.
The chemistry of the water supplied by the MWRA differs from that supplied by the Town of Winchester. The two main differences are:
MWRA uses chloramines – a mild and long-lasting disinfectant combining chlorine and ammonia (Winchester uses free chlorine).
MWRA water has a higher pH – around 9 to 9.5.
For more information, please read the Town of Winchester Water and Sewer Department Notice.
If you have any questions, please call the MWRA:
Joshua Das, 617-788-4822
