Water & Sewer Division

An Important Message from the 

Water and Sewer Division

The Water and Sewer Division continues its work to maintain our safe drinking water and collection system. During the Coronavirus crisis, we will continue to respond to emergencies such as water leaks and sewer backups. To ensure the safety of our employees and the community, please be aware of these important changes to our response and business practices:

Residential Sewer issues: If you are experiencing a sewer backup, crews will respond to determine if the backup is caused by the Town system or by an internal issue. We will attempt to clear the blockage from the outside. We will not be entering homes if the blockage is an internal issue. Please call a private drain company. 

  • Flushing wipes, paper towels and similar products down toilets will clog sewers, cause backups and overflows with internal plumbing and within the Town system. Read this article from the Boston Globe (March 25, 2020).  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. 
  • The sewer "safety rodding" program is currently suspended until further notice. 
Leaking Water Meter: If you are experiencing valve or water meter leakage in a basement, please call the Water Division at 781-235-7600 ext. 3355. We are evaluating these issues on a case-by-case basis and will advise homeowners. 

 WATER METER UPGRADE PROGRAM IS TEMPORARILY SUSPENDED DUE TO COVID-19

The Water and Sewer Division is currently upgrading Wellesley’s water metering system.  This 18-month long project is necessary but involves no additional charge to residents.
