Watertown plumbing systems
MWRA water is soft, with a hardness of about 15-20 mg/L (roughly 1 grain per gallon); MWRA considers water above 75 mg/L to be hard. MWRA adjusts pH and alkalinity with sodium carbonate and carbon dioxide, targeting a distribution-system pH of 9.3 and alkalinity of 40 mg/L.
There are approximately 9,250 water services on record in Watertown and none are comprised completely of lead pipe; however, older iron services were connected to the main with short lead "goosenecks" typically about two feet long, which the City removes each year during road reconstruction, water system improvements and incidental repairs from service leaks.
Watertown has received $1,800,000 from MWRA's Lead Service Line Replacement Loan Program, part of $72.4 million distributed to 22 communities through December 2025.
All existing or new building drains from plumbing fixtures liable to backflow from a DPW sewer, or from a private sewer connected to a DPW sewer, are required to have backwater valves installed at the owner's expense. Any fixture below the top of the manhole on the DPW sewer serving it is liable to backflow.
