Hydrant Flushing and Painting (3/12/19 )

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 to date.  Hydrants with the reflective whips on them are hydrants that have been flushed under this program.  During the spring, summer and fall we paint hydrants.  In 2019 we plan on painting hydrants on Wild Harbor Road, Sippeswissett and Quissett Ave and the Akapesket Penninsula.  

Water Quality - Lead and Copper (3/28/19)

In accordance with our testing plan we  sampled for lead and copper at 61 private homes in the fall of 2018.  We have commenced with the 2019 spring round of testing.  During the Fall testing cycle, 3 of the 61 homes tested above the action level for lead and those homeowners were notified.  The lead is not from the source water, but is present in the 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 -  (3/12/19)

Your water is supplied from several sources. 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 is our primary sources, and has been since 1898.  In 2017 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 in 2017.
  • Fresh Pond Well  was taken off line early in 2017 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 northen side of the Mass Military Reservation. The Town obtained 12% of the total supply from this source.
