EnergySolutions : Eversource Begins Natural Gas System Upgrade Project in Putnam

Company investing $474,000 to increase safety and reliability for customers

BERLIN, Conn. - To ensure the safe and reliable delivery of natural gas to its customers, Eversource is investing $474,000 to upgrade the gas distribution system in Putnam. The project includes replacing more than 1,670 feet of existing cast iron and bare steel gas main with newer plastic pipe - which is safer, more durable and better able to handle fluctuations in underground temperatures. Since 2012, Eversource has replaced more than 120 miles of older gas main around the state.

'These investments allow us to further modernize the gas distribution system, minimizing repairs and any service interruptions,' said Al Marsocci, Vice President of Gas Operations at Eversource. 'Proactively upgrading the system helps to ensure the continued safe and reliable delivery of natural gas to our 226,000 customers in Connecticut.'

The Putnam upgrade project is underway, with construction crews working between the hours of 7 a.m. and 4:30 p.m., Monday through Friday. Work will be done along Chassey, Farrows, Leyden and Walnut streets.

Eversource communicates with community leaders and customers where work is being done to minimize the impact to traffic and coordinate with other roadwork happening in the town. Drivers may experience delays due to alternating one-way traffic. Customers may experience a short disruption to their natural gas service when the new main is being activated and they will be notified in advance by letter, phone or an in-person visit. This gas main improvement project is expected to be complete by early June.
