WILMINGTON — Crews working for Vectren have begun the process of replacing gas mains and service lines throughout the state as part of the company’s pipeline replacement program, which is a multi-year program to replace about 700 miles of bare steel and cast-iron pipeline infrastructure in more than 40 cities or towns in west central Ohio.

This year, 21 west-central Ohio cities will be impacted — including Wilmington — and crews will retire more than 60 miles through an investment of nearly $58 million.

These infrastructure enhancements are vital to meeting federal requirements and ensuring safe delivery of natural gas service to customers for decades to come, the company stated in a news release.

Replacement work is prioritized based on pipeline assessment and leak repair data as well as the opportunity to minimize the construction impact to the affected city.
