Chesapeake strives to ensure that pipelines are built to last. Pipeline routes are inspected by foot, vehicle or airplane to regularly check the surface above the pipeline.
Pipeline cleaning and inspection tools, called PIGs, can be inserted into the line at locations called PIG launchers. Using fluid pressure for movement, PIGs sweep through the pipeline gathering any residual moisture or sediment contained in the pipeline and pushing the debris to a location where it can be removed.

Smart PIGs have the capability to accurately detect and locate any pipeline anomalies.

Another maintenance method used to prevent the occurrence of corrosion involves the use of cathodic protection. This common technique uses a low-voltage electrical current to protect the pipe from corrosion. Cathodic protection systems are utilized in many industries to protect fuel pipelines and storage tanks, ships, offshore oil platforms and onshore oil well casings.​
