Gas pipeline upgrades underway in Washington

Washington, Ind. - Contract crews working for Vectren Energy Delivery (Vectren) have begun replacing gas mains and service lines in Washington as part of the company's pipeline replacement program, which is a multi-year program to replace about 1,300 miles of bare steel and cast iron pipeline infrastructure throughout Indiana. In Washington, nearly $4 million will go toward retiring nearly seven miles of gas main and nearly 500 service lines in 2018. Since 2008, nearly 17 miles have been replaced within the city. Vectren intends to replace a total of 29 miles in Washington over the next several years.

"To ensure the continued reliability of our natural gas pipeline systems and service, our program to replace essentially all of our bare steel and cast iron pipeline infrastructure carries on," said Brad Ellsworth, Vectren Energy Delivery of Indiana-South president. "As we continue to modernize our pipeline infrastructure, we remain focused on strengthening our system to not only meet federal requirements, but ensure the safe delivery of natural gas service to our customers for decades to come."

Streets affected during the first two projects include: NW 15th Street, NW 16th Street, NW 18th Street, Smoot Street, North Street, Vincennes Avenue, Jackson Street, N. Meridian Street, NW First Street, W. Maple Street, NE Third Street, NE Fifth Street, NE First Street, NW Second Street and E. Flora Street. Visit the Active Projects tab onwww.vectren.com/pipelinereplacement to view an interactive map displaying all streets in Washington where construction will take place in 2018.

In most cases, a polyethylene (plastic) system is being installed to replace the current bare steel and cast iron gas pipeline system. First, the gas main will be replaced within the right-of-way, and then the service lines running directly to homes and businesses will be replaced. Upon completion of the project, affected yards, sidewalks and streets will be restored.

"Construction for these pipeline projects may take several weeks to complete, and times may vary based on the size of the project, weather, ground surface/soil and other situations that may arise," said Ellsworth. "Please be assured that Vectren and its contractors will make every effort to complete each project as quickly as possible and minimize impact to customers and the community."

Vectren reminds Washington residents to please keep the following in mind:

• • Please exercise caution when driving through the construction zones.

• • We urge residents and their children to keep a safe distance away from any work zones.

Washington is one of nearly 75 cities in Indiana undergoing this type of pipeline replacement. Since 2008, nearly 150 miles of gas mains have been retired in the Vectren South territory, which has led to a reduction in leak calls and natural gas emissions from the distribution system.
