National Grid has restored gas service to all but 12 of the approximately 300 Woburn homes that lost service as a result of a pipeline pressurization error Monday, officials said Thursday.
Crews from the regional gas supplier worked to reintroduce gas into the system this week. Throughout the day Wednesday, the crews relit customers who had lost service, National Grid spokeswoman Christine Milligan said.
In order to relight customers, National Grid employees had to go door-to-door and turn on the gas from inside people’s homes. The 12 homes that still did not have gas by Thursday morning were the 12 locations where no one answered the door Wednesday, Milligan said.
National Grid employees left door hanger placards on those homes notifying the residents of the company’s attempt to restore gas. Those homes will have their gas turned on again as soon as the residents call National Grid, which continues to have crews stationed in Woburn, Milligan said.
Hundreds of families saw their gas service abruptly stop Monday when officials cut the flow of gas to their homes after a pressurization issue. Officials said the pressure rose when a worker accidentally introduced excess gas into a section of the pipeline system during routine maintenance work near Wyman and Hart Streets.
The pipeline system was not damaged, but the gas was shut off as a precaution after the incident, which officials attributed to “human error.”
National Grid and employee unions are locked in a protected contract dispute that has led to the lockout of union members.Travis Andersen contributed to this report. Andres Picon can be reached at email@example.com. Follow him on Twitter at @andpicon.
