(P&GJ) — Eversource is replacing more than 18,600 feet of aging natural gas lines in Danbury, Conn., as part of an accelerated program to improve safety and reliability for customers. The work involves swapping out leak-prone cast iron and bare steel pipes with high-density plastic, which is designed to last for decades.
Since 2018, the utility has replaced nearly 200 miles of older gas mains across the state.
“Cast iron and bare steel mains become brittle over time due to the freezing and thawing cycles we experience in Connecticut, which is why for the last several years replacing those leak-prone pipes has remained a top priority for us,” said Michael Needham, Eversource vice president of gas operations. “These vital improvements reduce carbon emissions, modernize the gas distribution system, and minimize repairs and any service interruptions. Not only do these critical investments result in strengthened reliability for our customers, but they also enhance public safety for our communities.”
The project includes replacing dozens of customer service lines and moving most inside gas meters outdoors. Work is taking place in multiple areas, including 9th, Forest, Virginia and Westville Avenues; Ohehyahtah Place; Golden Hill Road; and 5th, Abbott, Beckett, James, Montgomery, Stevens, West, West Wooster and White Streets.
Eversource is coordinating with community leaders to reduce traffic impacts and align with other roadwork. Customers may experience brief service interruptions during line activation, with advance notice provided. Weather permitting, the current upgrades will be completed by year-end, with final road restoration dependent on project timelines.
An additional 25,000 feet of gas main replacement in Danbury is planned for 2026.
