Greater Portland's supplier of natural gas is set to begin a 14-year, $60 million project to replace or upgrade more than 100 miles of underground gas pipeline throughout Portland and Westbrook.
Residents who want the latest information on the Greater Portland natural gas pipeline replacement project will be able to call a toll-free hotline at (866) 821-4386 or go to a website dedicated to the project, at www.ngupgrade.com.
The replacement project is one of the largest of its kind ever undertaken in the Northeast, according to Unitil, the Hampton, N.H.-based company that operates the system. Unitil bought Northern Utilities in 2008.
Work is expected to start in early April in Portland's Old Port. Construction also is set this year for the Veranda Street - Washington Avenue area. No work will be done during the winter.
Unitil says there are no imminent safety concerns with the network but some cast iron lines are more than a century old and must be replaced. They will be upgraded to plastic pipe.
