Water Distribution System

Sharon Aquifer Map 1987Sharon relies on local groundwater aquifers for its drinking water.  The system currently serves about 17,500 customers or approximately 98% of the Town.

Water Mains
The Town’s water delivery system includes about 120 miles of pipe. Some of the pipes are unlined, small diameter cast iron water mains that are over 100 years old.

Water Storage Tanks
The Town maintains four water storage tanks with a total volume of 3 million gallons.

Water Supply Wells
The Town obtains its water supply from four gravel pack wells: Wells 3, 4, 5, and 6, and two well fields: Wells 2 and 7.

Each production well is comprised of a well point or series of well points, and motors that drive pumps.  Some pump stations have auxiliary power, others do not.

The combined MassDEP approved pumping rate of the groundwater supplies from all the sources is 3.12 million gallons per day (mgd).

Well stations and water tanks are monitored via the SCADA System (Supervisory Control and Data Acquisition), which controls well pumping and water levels at each of the storage tanks.

Water Treatment

All wells are treated with sodium hypochlorite for disinfection, sodium fluoride for dental protection, and potassium hydroxide for pH adjustment/corrosion control.

Sharon Water Quality Reports

Help Protect Our Water Supply

As a consumer, you have an impact on the quality of our water supply  sources, and  therefore,  the quality of the water you drink.

Our groundwater is highly susceptible to contamination from residential activities adjacent to the wells; residential land uses; accidental spills from local roadways, Route 95 and the railroad; hazardous materials storage; existing contamination sites; and
agricultural activities.

The land around our groundwater wells is mainly forested and residential with lesser amounts zoned as commercial.  When rain falls or snow melts, the seemingly small amounts of chemicals and other pollutants around your property may be transferred by groundwater or overland flows to the wells.  This contaminated water is called stormwater runoff, and it can be a major source of water pollution.

You can reduce stormwater pollution and help keep our water clean by regularly maintaining your septic system; reducing chemical use around your lawn and in your house; and by picking up after pets and throwing the waste into a trash can.
