The pipes that carry natural gas through the heart of Zionsville are getting an upgrade. Vectren is working to replace bare steel cast iron transmission pipelines with polyethylene pipes. Polyethylene is the new industry-grade material, and Vectren is installing it across its service area to ensure continued integrity.

Zionsville is part of a large, multi-year project in which 1,300 miles of Vectren’s infrastructure is being replaced. In 2015, Vectren will retire .4 miles of bare steel cast iron pipe in Zionsville, and more than 4.4 miles will have been replaced in the town since 2008. This work is currently underway and impacts about 70 of Vectren’s customers.

In addition to pipeline replacements, Zionsville projects slated to begin mid-May include the retro-fitting of a 16-inch transmission pipeline that runs for 8.6 miles through the town. After the work that will replace the valves and 90 degree elbow joints with rounded ones, this particular pipeline will become “piggable.” Vectren will be able to perform a new in-line inspection using a device called a smart pig – named so due to the squealing sound it makes as it passes through the pipe. This new form of inspection will be added to Vectren’s regular seven-year inspection rotation.
