ConEd: Replacing aging gas pipelines could take decades

|By:, SA News Editor

Consolidated Edison (ED) reckons it will take four decades - and cost $10B - to replace the hundreds of miles of aging iron and unprotected steel gas pipelines that form a large part of its infrastructure.

The issue has taken on new urgency following the gas explosion in Harlem in March, which killed eight people and injured dozens of others.

From 2010-2013, ConEd replaced 83 miles of cast-iron pipelines, leaving it with another 1,110 miles. ConEd has another 1,084 miles of unprotected steel gas pipes, nearly all of which the utility intends to replace.
