Infrastructure Projects

System improvements, upgrades and projects

We are continuously working to maintain and improve the water system.  Some of the major projects we are currently working on involve the installation of new, or the replacement of existing, equipment and facilities needed to provide safe, reliable water service.

Pipeline Replacement Project - Greenwich/Stamford

Nov 19, 2021 Connecticut

Project Goals and Objectives

The project is part of an ongoing program to improve Aquarion’s water supply system. The infrastructure upgrades will also help to reduce leaks and improve the transfer of water from the Bargh Reservoir to Rockwood Reservoir.

Scope of Work

Aquarion will replace an existing 20-inch raw water pipeline between Bargh Reservoir Dam in Stamford and the Rockwood Lake watershed in Greenwich.

Project Status

  • Aquarion has been working hard to reconstruct the roadway by removing the existing material in the roadway and replacing it with new process aggregate as directed by the City of Stamford.  This work should be completed and the area graded prior to Thanksgiving.  At this time, the plan is to pave the week after Thanksgiving if the weather and temperatures meet the requirements for paving.
  • Guard rail has been ordered and we are waiting for a delivery time from the supplier, which is expected later in December.



  • Aquarion is working with the contractor to identify the final remaining leak on the main.  Once this is located, final pressure testing will be completed and pavement will be restored.  We are presently working with the Town of Greenwich on a paving plan before winter.
