Water and Sewer Update June 25,2020 

The Water and Sewer Division continues its work to maintain our safe drinking water and collection system. During the Coronavirus crisis we have continued to respond to emergencies such as water leaks and sewer backups.

As Massachusetts is beginning to reopen we have started scheduling non-emergency services with proper precautions in place.  Residents are now able to schedule sewer safety roddings and water meter installations. To ensure the safety of our employees and the community we are asking to maintain proper social distancing practices if a site visit is necessary. We do ask to limit exposure to your living space, therefore, any direct entrance into the basement is ideal for these operations.  

Help Prevent Sewer Backups​

Flushing wipes, paper towels and similar products down toilets will clog sewers, cause backups and overflows with internal plumbing and within the Town system.  Even wipes labeled as "flushable" will clog pipes and interfere with the sewer collection system and pumps. Please dispose of these items in the trash. 

Please NEVER Flush:

  • Paper towels, disposable wipes, washcloths and rags
  • Any synthetic materials such as plastic, which do not decompose or dissolve
  • Feminine products
  • Cotton balls or cotton swabs
  • Unused medication or syringes
  • Fats, oils and grease
