The Board of Water Commissioners voted to remove the outdoor water restrictions that were in place since May 2016. The restrictions were removed due to the onset of winter and customers are asked to concentrate on conserving water indoors.
We test our sources for total manganese on a monthly basis. The results of these tests will be posted on this page as they become available. All results are shown in micrograms per Liter unless otherwise noted. The value shown is the average for the month if multiple samples were taken.
Please review the public notice that was sent to our customers in November 2013 to see how these levels compare to guidance from MassDEP. Manganese levels typically decline as water moves futher away from the sources because it precipitates out of solution and coats the pipe walls. Although system levels are normally low (<300 micrograms per Liter) this level can easily be exceeded when sediment in water mains and home plumbing lines is disturbed.
A system map (14 MB) showing the test sites and water mains is available to help customers determine which sampling sites are closest to their homes.
The Town approved funding for the design of a water treatment facility to remove manganese from the source water. The Town has hired Woodard & Curran as the Owner's Project Manager and Wright-Pierce as the designer. Design work is underway and we expect to go out to bid for the construction of the plant prioir to Town Meeting in May 20017. If approved construction would begin during the summer of 2017 and the plant would be operational in the fall of 2018.
December 2016: Reviewing 60% design plans and contracts.
September 2016: Soil borings were conducted along transmission main routes. Review of the Basis of Design report continues.
August 2016: We've received and are reviewing the Basis of Design report prepared by Wright-Pierce. This report describes the design parameters for the plant, required equipment, etc.
July 2016: Actual design work begins with the development of the Basis of Design Report. Surveying along the water main routes continues and layout of easements begins.
June 2016: MassDEP approved the pilot test report.
March 2015: We've reviewed the pilot test report and it was submitted to MassDEP for approval. Testing results were very favorable. All finished water manganese lab tests were below detection limits. An aeration process and permanganate system was added to the project as a result of the pilot testing.
December 2015: Pilot testing was completed and the results look very favorable. We expect the report by mid-January. Work has started in obtaining one or more easements needed for the installation of the raw water transmission main. The easements are needed to reduce or eliminate the amount of pipe installed on Route 1.
Water customers will receive a copy of the updated Manganese Drinking Water Advisory notice in the mail shortly. The Water Department instituted an advisory in 2013 due to manganese contamination. Recent tests have indicated on of our sources exceeds the MassDEP limit of 300 micrograms per Liter of manganese.
We conduct hundreds of water quality tests each year. Results are now available on our Water Quality Site which includes information about which water sources are in use. The site has been under development for several years and more functionality will be added as time permits.
