Water Supply Sources

Where does your water come from?

The Town of Maynard's water comes from seven groundwater sources. Four of the  sources consist of 40 to 70 feet deep wells and constructed in sand-and-gravel deposits that overlie bedrock; they are located in the southern half of Maynard. The remaining three sources care approximately 400 feet deep into bedrock and located in the northern half of Maynard. 

White Pond, a surface water supply located in Hudson and Stow, is no longer in service; however, it remains available as a future source if treatment is implemented. For more information on our current sources and future sources please look at  Water Resources Report 2011.

How is the water treated? 

The town has the infrastructure to supply 1.3 million gallons per day or MGD of treated drinking water from three treatment plants known as Old Marlboro Road Treatment Facility, Green Meadow Treatment Facility and Rockland Avenue Treatment Facility. All three water treatment facilities use greensand filters to remove iron and manganese, and they add chlorine for disinfection. In addition, the Old Marlboro Road and Green Meadow facilities add potassium hydroxide to control corrosion in household plumbing. The Rockland Avenue facility is equipped with an air stripper to remove radon, a naturally occurring contaminant in bedrock wells. The water we deliver must meet specific health standards and is monitored for many different substances on a very strict schedule. Detecting a substance does not mean the water is unsafe to drink; our goal is to keep all detections below their respective maximum allowable levels.
