Water Department


Our mission is to provide the Town with safe, potable drinking water through careful management and operation of the existing sources of water, and through ongoing maintenance and operation of the distribution system.

Long Pond Water Treatment Plan (12/18/17)

At 11:30 AM on October 18, 2017 the Long Pond Water Treatment Plant began pumping water into the distribution system.  The plant takes water from Long Pond, removes the algae, ozonates the water, filters the water through activated carbon and disinfects it with sodium hypochlorite.  During the week of November 17th Long Pond water turned over as the surface layer got colder.  In past years consumers experienced discolored water when the pond turned over.  After 60 days of operation, exceeding all performance parameters, we we have begun to slowly reduce the amount of chlorine that we add for disinfection going from a target of 2 mg/l to a target of 1.8 mg/l  as the system wide demand for disinfection is decreasing with the flow of water from the new plant.   

Irrigation and Conservation of Water (July 21)

To conserve water please only irrigate on alternate days, on days it has not recently rained, and in the evening, at night or early in the morning.   Irrigation systems need to be properly maintained to avoid  waste of water due to leakage. 

Water Quality Notifications (10/27/17)

In accordance with DEP regulations and guidance notifications have been mailed to all customers regarding two issues.  One is that the Town only had one form of disinfection on an the unfiltered water from Long Pond.  This has been corrected by the start up of the new filter plant.   The other is an exceedance of lead levels at 4 of the 30 homes tested in July of this year.  The lead is not from the source water but is present in piping in older homes.  For more detailed information open and read the documents on the right titled "Public Notification regarding unfiltered supply disinfection" and "Lead and Copper Public Education Program".
