Every day, Ameren Illinois delivers natural gas to 840,000 customers in central and southern Illinois. Our pipeline system including about 18,000 miles of pipeline - is part of a vast national network that transports huge volumes of energy products to Americans every day.

Accidental pipeline releases are rare, but can be dangerous because of the flammable nature of gas. To ensure the safety of our pipelines, we follow detailed operating, maintenance and communication plans.

Our highly trained employees constantly monitor our system and perform regular maintenance to ensure proper pressure control, odorization and reliable service. In addition, all new gas service installations include excess flow valves to stop the flow of gas in the event a service line is hit or ruptures.

Excavation Damage is the biggest threat to pipeline safety. You can help prevent potentially dangerous incidents by calling JULIE at 811 before any digging project and by reporting suspected gas leaks. Working together, we can keep the energy flowing and our homes and communities safe.
