Where Does Your Drinking Water Come From?

In the Neponset River Watershed, drinking water supplies vary based on the town that you live in.

Watch the video to learn more about water delivery.

In the towns of Foxborough, Canton, Dedham, Dover, Medfield, Randolph, Sharon, Stoughton, Walpole, and Westwood, drinking water mainly comes from groundwater aquifers.  (A number of these towns are also connected to the MWRA reservoirs for supplemental or back up purposes.)


Groundwater fills the spaces between soil particles and fractured rock beneath the earth’s surface.


The communities of Hyde Park, Mattapan, Milton, Norwood, and Quincy get their drinking water from the Massachusetts Resources Water Authority (MWRA) reservoirs.

Some water is treated extensively before drinking, some water needs less treatment.  Once water is used and becomes wastewater, it may be treated by a septic system or, more likely, a sewer system.  It all depends on where you live!

For more detailed information on your drinking water supply, call your local water department, or look up your town’s Consumer Confidence Report (CCR), which describes the town’s water system, quality of water, and anything else related to the drinking water in your community.

The Federal Safe Drinking Water Act requires each public water system to develop and distribute a CCR to its customers each year.

    Just a correction: Stoughton get most of its water from local sources – MWRA supplies less than 10% in most years.
