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.

Hydrant Flushing and Painting (10/10/19 )

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.  We are currently painting hydrants whenever the weather cooperates.  We recently completed the hydrants out to Penzanze Point and along Teaticket Highway.  We will be in the area of Locust Street next week.  

Backflow Prevention - Public Notice (7/12/19)

We recently sent a notice to all users to educate them on how to avoid a backflow event.  Homeowners need to be sure that if they have underground irrigation that there is an approved backflow device between the water suppy and the irrigation system.  For more info see the informational documents to the right.

Water Quality - Lead and Copper (7/12/19)

Every Spring and Fall the Water Department, as part of its corrosion control program, samples the tap water at selected homes for lead and copper.   sixty homes need to be sampled to have a large enough sample set to be statistically valid.   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.   Interested? 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.

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 -  (7/12/19)

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.  During this summer it supplied over 80% of our daily water needs..
  • The Crooked Pond Water Plant treats water from both the Crooked Pond Well and the Coonamessett Well and provided 16.7% of the water in 2018.
  • Mares Pond Well provided  3.0% of our water in 2018.
  • From the Upper Cape Regional Water Co-op, we obtain water from wells located on the northern side of the Cape. 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 398 miles of water main, 4 water storage tanks and approximately 22,000 service connections.
