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.

Hillside Ave, Hillside Ct, Hamilton Ln, Casement St, & Patricia Ln Main Replacements - Darien

Jun 9, 2022 Connecticut

Project Goals and Objectives

A water main replacement project is scheduled to begin in Darien on Hillside Avenue, Hillside Court, Hamilton Lane, Casement Street, and Patricia Lane and is expected to be completed by late fall. Final paving will then be scheduled in coordination with the Town of Darien.

Scope of Work

The project, which will replace approximately 5700 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. 

To keep customers informed about scheduled/unscheduled work, Aquarion utilizes an Everbridge notification system to call affected customers. Aquarion encourages customers to sign up for this free service at

Thank you for your patience as we proceed with this important project.
