With robot on job to fix leaks, we have an answer to the push for more pipelines

For years, construction and natural gas companies have been trying to force gas pipelines on New England communities that don’t want them. And for years, environmentalists have been urging the gas companies to fix leaks in existing pipelines, which would eliminate anticipated gas shortages.

The new, noninvasive, low-cost repair method described in the Globe last week (“To fix buried gas mains, a robot dives in,” Page A1, May 30) should remove the last excuse for building new pipelines. We can invest in fixing dangerous leaks and provide time to build up offshore wind and solar.
