July 30 - 2018 Heat Wave and Water Conservation

We are asking all water system users to avoid wasting water during this heat wave. During early morning hours there is spike in the demand for water. We attribute that spike to the use of irrigation systems. Please minimize the amoutn of irrigation.  If you must irrigate or water your lawn or garden we remind you to do it at night and to follow the odd/even rule.  Only Irrigate on alternating days. If you are living at an odd numbered home only irrigate on odd numbered days.  If you are living in an even numbered home only irrigate on even numbered days.  



Mission


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 (07/30/18)

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 operating at near full capacity, as intended.  Currently  75% of the water in the system is being produced by this plant.  We are disinfecting with hypochlorite at a rate of 1.2 mg/l and system wide we measure residual chlorine levels of 0.7 to 1.1 mg/l.    


Hydrant Flushing and Painting (07/30/18 )

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 todate.  Hydrants with the reflective whips on them are hydrants that have been flushed under this program.  During the summer we paint hydrants.  We have painted the hydrants on Gifford Street and are currently painting the hydrants on Blacksmith Shop Road.      
 

Water Quality - Lead and Copper (07/30/18)


In accordance with our testing plan we sampled for lead and copper at 61 private homes this spring/early summer as well as at the east falmouth elementary and the High School.  No lead was measured at the two school sites.  3 of the 61 homes tested above the action level for lead and those homeowners have been notified.  The lead is not from the source water, but is present in 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 currently 8.03.   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.
