Well water now, MWRA water later
Wayland supplies its own water from wells, including the Baldwin Pond and Happy Hollow wellfields. In 2025 the town filed plans with the state for a permanent connection to the MWRA system through Framingham. The schedule in that filing has construction finishing in 2029.
For a water heater that means two things. Today the water is well water, which usually carries more minerals than MWRA water, so flush the tank at least once a year. MWRA water, when it comes, is soft. What hardness does to a tank.
The housing
About 88 percent of Wayland homes are single-family. The median home was built in 1962, and 63 percent heat with gas.
Two gas companies
Eversource serves part of Wayland and National Grid serves the rest. For a gas smell, leave the house and call 911. The gas emergency lines are 800-592-2000 for Eversource and 800-233-5325 for National Grid.
Eversource supplies the electricity, so Mass Save's 2026 rebate of $750 on a heat pump water heater applies.
