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.

Long Pond Water Treatment Plan (01/18/19)

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. The plant is in its second year of operation.  Currently  25% of the water in the system is being produced by this plant.  We are disinfecting with hypochlorite at a rate of 0.9 mg/l and system wide we measure residual chlorine levels of 0.4 to 0.7 mg/l.    

Hydrant Flushing and Painting (10/28/18 )

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 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 2018 we have concentrated on painting hydrants on the main roads including Gifford Street, Blacksmith Shop Road, West Falmouth Highway, Central Ave, Davisville Road, John Parker Road, and Marivista.    

Water Quality - Lead and Copper (10/28/18)

In accordance with our testing plan we are again sampling for lead and copper at 61 private homes this fall.  The fall results will be summarized when completed in November.  During the Spring 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 - 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 approximately 8.0.   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.
