Ameren Illinois said its crews will be removing mechanically-coupled, vintage steel natural gas mains and services and replacing them with corrosion-resistant polyethylene infrastructure that is less prone to shifting as the ground freezes and thaws.

The Collinsville, Illinois-based utility said it also will upgrade the pipelines to the homes of nearly 1,200 individual natural gas customers.

The largest project will be in the Village of Grandview, where more than 420 services will be upgraded and 18,800 feet of pipeline will be installed. Work is scheduled to begin in March and be completed by the end of July.

Crews will be begin work after the Independence Day holiday in nearby Leland Grove, installing 19,000 feet of polyethylene pipe and 263 services. The work is expected to be completed by the end of October.

In the Northgate subdivision, crews are already working to install 15,000 feet of polyethylene pipe and 250 services to homes. Weather permitting, crews should complete the job in mid-May.

Starting in late April, crews will install new pipeline for the entire Village of San Jose. Ameren Illinois employees will install 26,250 feet of polyethylene pipe and 200-plus services. Completion is targeted for late June.

The Springfield and San Jose projects are part of Ameren Illinois' plan to replace nearly 600 miles of mechanically coupled steel natural gas distribution pipelines in central and southern Illinois. As part of its planned system upgrades around the state, the company recently said it is replacing 12 miles of aging natural gas pipeline in the Pekin and Glen Carbon areas for a combined cost of $64 million.
