July 2 - 2018 Heat Wave and Water Conservation

We are asking all water system users to avoid wasting water during the heat wave. July 4th weekend we have many visitors and there is a very high demand on the water system.   If you must irrigate or water your lawn or garden we ask that you do it at night and follow the odd/even rule.   Irrigate on alternating days with those on the odd number side of the street irrigating on odd numbered days and those on the even numbered side irrigating on even numbered days. 


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 (06/15/18)

The Long Pond Water Treatment Plant takes water from Long Pond, removes the algae, ozonates the water, filters the water through activated carbon and disinfects it with sodium hypochlorite.  75% of the water in the system is being produced by this plant.  We are currently disinfecting with hypochlorite at a rate of 1.2 mg/l and system wide we measure residual chlorine levels of 0.7 to 1.1 mg/l.    

Hydrant Flushing and Maintenance (05/23/18 )

Open the document to the right named  "Hydrants flushed 5-23-18" to see a map with all the hydrants located.  Highlighted hydrants are the ones that have been flushed since 2016.   We flush during the spring and the fall each year.  We have flushed over 50% of the 3000 hydrants todate.  Hydrants with the reflective whips on them are hydrants that have been flushed under this program.       

Water Quality Notification (10/27/17)

In accordance with DEP regulations and guidance, a notification was mailed to all customers regarding lead on 10/27/17.  There was an exceedance of  acceptable lead levels at 4 of the 30 homes tested in July of 2017.  The lead is not from the source water, but is present in piping in older homes and may leach into the water if the water is stagnant for a long period of time.  For more detailed information open and read the documents on the right titled "Sampling for lead at your house's tap" and the 2017 public education brochure - lead". 

Water Supply - 2017 Annual Statistics

Your water is supplied from several sources. Total flow for 2017 was 1,634 million gallons.  To see a map click on the document link for Water Resource Areas on the right side of this page.
  • Long Pond  is a protected surface water reservoir it provided 52% of our water.
  • The Crooked Pond Water Filtration Plant treats water from both the Crooked Pond Well and the Coonamessett Wells and provided 25% of our water.
  • Fresh Pond Well  was taken off line early in the year due to perchlorate being detected at 2.2ppb, above the allowable level of 2.0ppb.  It provided roughly 4.2% of our water.
  • Mares Pond Well provided  6.6% of our water.
  • From the Upper Cape Regional Water Co-op, the Town obtains water from wells located on the Mass Military Reservation. The Town obtained 12% of the total supply from this source.

Water Treatment (06/15/18)

All sources are disinfected with sodium hypochlorite and treated with sodium hydroxide to provide pH adjustment. The average pH of the water in the system is currently 8.03.   Water is then delivered to your residence through our transmission and storage system, comprised of 370 miles of water main, 4 water storage tanks and approximately 22,000 service connections.
