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.

Nawthorne Road and Keofferam Road Main Replacement - Greenwich

Apr 27, 2022 Connecticut

Project Goals and Objectives

A water main replacement project is scheduled to begin in April 2022 on the following streets: Nawthorne Road and Keofferam Road in Greenwich.  Final paving will then be scheduled in coordination with the Town of Greenwich.

Scope of Work

The project, which will replace approximately 2700 feet of water main, is part of an ongoing program to improve Aquarion’s water distribution system and to ensure the highest quality water.  The upgrades will also help to reduce leaks and water main breaks that can cause service interruptions. Due to construction, customers should expect minor traffic delays and possible detours during the working hours of 7:00 a.m. to 5:00 p.m. 

The project on Keofferam Road will require that your existing water service be connected to an above ground temporary water main during construction.  It will be transferred over to the new water main once it is complete.
