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.

Main Street and Route 28 Water Main  (5/17/19)

We will continue to install the 16 inch water main in Teaticket Highway Monday through Thursday next week May 20th to May 23rd..We will not work on Friday the 24th to minimize any traffic impacts as we roll into the Memorial Day Weekend.
We will start just past Falmouth Lumber and continue westward on Route 28. We should be in the vicinity of Broken Bow and Norris Path by the end of the day Thursday.  As of Friday the 17th we have switched the alignment of the pipeline from the North Side of Route 28 to the South Side of Route 28.  This eliminates conflicts with the existing water main’s alignment, and should help us to stay on schedule.

We have a request in with Mass DOT to allow us to continue to construct after Memorial Day weekend up to Friday June 14th.  We anticipated a favorable decision on that request. We would resume construction on Tuesday morning after Memorial Day.

Expect  traffic delays. Go to http://www.falmouthmass.us/986/Traffic-Updates to see updated plans. If you want to be on a notification list for the project send an email to steve.rafferty@falmouthma.gov with your email address.     

Hydrant Flushing and Painting (5/17/19 )

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.  We have commenced with the 2019 painting program and we continue to focus on the main roads - we have completed Jones Road and will be doing Quaker Road next.

Water Quality - Lead and Copper (5/17/19)

In accordance with our testing plan we  are sampling for lead and copper at 61 private homes in the Spring of 2019. We have received 30 test results and all homes are below the action level for lead and copper.  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 -  (5/17/19)

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 2018 it provided 69.5% of our water.
  • The Crooked Pond Water Filtration Plant treats water from both the Crooked Pond Well and the Coonamessett Wells and provided 16.7% of our water in 2018.
  • 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 was not used in 2018.
  • Mares Pond Well provided  3.0% 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. In 2018 the Town obtained 10.8% of the total supply from this source.

Water Treatment (5/17/18)

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 approximately 8.0.   Water  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.
