As part of the ongoing Eversource Sudbury to Hudson Transmission Reliability Project, the Sudbury Water District is working closely with Eversource to upgrade infrastructure along the project route. The project has now advanced to the Boston Post Road (Route 20) crossing at Station Road, where a section of water main is scheduled for replacement. This work will require a temporary interruption of water service within the construction zone. To minimize disruption to nearby residents and businesses, the work has been scheduled during overnight hours. We appreciate your patience and understanding as we complete this essential infrastructure upgrade to ensure the long-term reliability of our community’s water system.

Construction Schedule:
Sunday, April 28, 2025 through Tuesday April 29, 2025
9:00 pm to 5:00 a.m. (approximately)

Exact Utility Construction Location:
Boston Post Road at Station Road

Water Service Outage:
Boston Post Road/Route 20 (394 – 400)

Outage Duration:
8 hours each day (estimate)

Number of Services Without Water:
3

Reason for Outage:
Planned Water Main Replacement

Homes and businesses in close proximity to this area of town may experience fluctuating pressure (air in pipes) or discolored water (mineral sediment lifting from the bottom of the pipes and traveling with the water-flow inside the main.) Running your water after construction is complete from a cold tap briefly will assist in clearing your service line of air and minerals.

Is the water safe to drink? Slight discoloration may sometimes linger for a few hours, it is not harmful to your health and only temporarily affects the appearance of the water, it does not influence water quality. Water conditions typically improve overnight.

Preparing for a water outage:

  • Fill pots on the stove with water for cooking
  • Fill a couple of buckets with water for washing
  • Fill potable water containers for drinking (assume about one gallon of drinking water per person per day)
  • Fill bathtubs with water and use buckets to flush toilets, a toilet will flush when approximately a gallon of water is dumped into the bowl

During a water outage:

  • Try not to operate water faucets, dishwashers, or washing machines. This will prevent air from entering your plumbing.

Once water service is restored:

  • Flush your plumbing lines by opening a large tap while all other taps remain closed. The bathtub(s) in a home are ideal for this task. Open the cold-water valve in the bathtub. Listen for hissing and spitting, a sign that air remains in the line. Run the water to flush sediment (minerals) until it is clear, and no additional air bubbles are released.
