Little Bay Road Water Main Replacement

Completed Updated July 15, 2026

Project Overview

This joint project with the Town of Newington involved the installation of an eight-inch ductile iron water main and the replacement of 25 water services and four hydrants. The project is substantially complete and was paved by the Town of Newington.  

Project Description:

This project replaced approximately 4,300 linear feet of eight-inch water main along Little Bay Road in Newington. Observations of the water main over many years of failures have made it clear that the breaks in the 1969 cast-iron water main are due to inadequate pipe bedding material and compromised portions of pipe. The replacement of this main was necessary to maintain a reliable water supply in this area.
