Gas-main Replacement on Commonwealth Avenue Now Underway

July 24, 2012

National Grid is now replacing 2,000 square feet of gas main on the inbound side of Commonwealth Avenue between Exeter and Hereford streets, according to company spokesman David Graves.

Graves said the project, which began July 5 and will continue through mid-October, entails the decommissioning of infrastructure that dates back to the early 20th century and replacing it with 8-inch plastic joints.

“It’s part of the overall replacement of leak-prone pipes,” said Graves, adding that 150 miles of gas main would be replaced in the Commonwealth this year alone. “It’s less expensive and has more long-term benefits for customers than simply patching the leaks.”

Graves said National Grid would also replace service lines that run to individual residential units and buildings beginning in mid-August.

“We will need to enter each building, shut off services and make the new connections before relighting any pilot lights, “ Graves said.

Graves said customers would lose service for approximately four hours while the new connection is made, and that National Grid will set up appointments with customers beforehand to minimize disruptions and accomodate their schedules.

In 2013, National Grid will replace another 2,000 feet of gas main on Commonwealth Avenue between Berkeley and Exeter streets, although no timetable has been determined for the project yet.

“We still have to go through the permitting process and arrange police details,” Graves said. “Our goal is to finish the project during [the pre-winter] construction season and possibly commence work after July 4 of next year.”
