Water Meter Upgrade Program


The Wellesley Department of Public Works, Water and Sewer Division is resuming the Water Meter Upgrade program. Notices will be reissued to residents who were not able to make appointments for the upgrade before the program was suspended.  Please note that notices are being sent out in a specific order so if you have not received one to date, the contractor may not have reached your section of Town. 

The contractor (Baystate Winsupply) installing these meters has implemented a COVID-19 control plan. Installation technicians are taking additional precautions before entering homes to help protect residents and the installers. Click here for the plan.

More information on the project specifics and the scheduling process is below. If you have any questions feel free to contact the Water Division at 781-235-7600 ext. 3355.

Project Specifics

In a continuing effort to improve Advanced Metering Infrastructure Diagramwater service to our customers, the Wellesley Water Division is implementing a Town-wide upgrade to our water metering system. Beginning in December 2019 and continuing through June 2021, the Water Division is replacing the old water meter system with a modernized Advanced Metering Infrastructure (AMI) system that will improve our ability to measure water usage, detect leaks, and better answer questions about water usage.

Presently, our meter reader drives by your home to receive data from your water meter. The new meters will transmit water data directly to the Water Division automatically on a daily basis. The new system will also provide our customers with the ability to review their water usage and set up alerts for unusually high water consumption.

Approximately 13,000 meters will be replaced or retrofitted during this project. The upgrade includes the installation of new water meters and transmitting devices at your home or business. The installation is necessary and will be performed at no additional charge to you.

Installation Process

The TBaystate Winsupplyown of Wellesley has hired a contractor, Baystate Winsupply, to carry out the installations on an appointment basis. 

All Baystate Winsupply employees will have photo ID badges and drive clearly marked vehicles. Do not allow any stranger into your home that does not have a photo ID badge and a clearly marked vehicle. Call Baystate Winsupply at 1-866-983-8080 if you have any doubts.

The Town has been divided into sections and the meter replacement process will occur one section at a time until completed. Every home in each section will be sent a letter via U.S. mail when it is time to schedule their appointments. Homes that have two meters - one for domestic water use and another for irrigation - will receive a letter for each meter. If you have two or more water meters you must schedule concurrent appointments with the same technician on the same day.  

Appointment Process

Customers and property owners will initially be contacted through a letter sent via U.S. mail. The letter will include instructions on how to schedule an appointment as well as the Work Order and Service numbers for their installation.

The appointment can either be scheduled online through the website provided in the instructions or by calling Baystate Winsupply Co. toll free at 1-866-983-8080, Monday through Friday, between the hours of 8:00 a.m. and 4:00 p.m.

Please do not try to schedule your appointment until you have received a letter verifying your work and service numbers. Appointments can only be made with Baystate Winsupply; please do not contact the Town of Wellesley to schedule an appointment.

  • Appointments for meter replacement are available at set times, Monday through Saturday, from 8:00 a.m. to 4:00 p.m.
