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  (6/14/19)

We have stopped pipe installation as of Friday, June 14th.   We will start up again after the summer on Wednesday, September 4th.   

If you have any comments or concerns, or 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 (6/3/19 )

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.  

Water Quality - Lead and Copper (5/30/19)

Every Spring and Fall the Falmouth Water Department, as part of its corrosion control program, samples the tap water at selected homes for lead and copper.    A minimum of 60 homes need to be sampled to have a large enough sample set to be statistically valid.   Homes have to generally be built before 1985 to be included in the program.  The use of lead based solder to fuse copper piping together was banned after 1985. 

We are looking for homeowners that are willing to participate in the sampling program.  Your home must have been constructed prior to 1983 to be eligible.   If you are interested please email(falmouthleadsampling@falmouthma.gov).   We will provide you with additional information and would want to conduct a visit to confirm that your piping has lead based solder.

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.
