Understanding How Pipelines Work

The Washington Gas system is part of a vast nationwide network of mostly underground pipelines that deliver natural gas. The company operates approximately 200 miles of transmission pipelines and thousands of miles of distribution pipelines.

Transmission pipe carries natural gas at high pressures from gate stations - where gas enters the system - to regulator stations, where pressure is reduced for distribution to customers. Pipeline markers indicate the presence, but not the exact location or depth, of transmission pipelines in underground rights-of-way. The markers identify the fuel, operator, and phone numbers to call before digging or excavating. Less than half of Washington Gas' transmission pipe is in high consequence areas, where gas leaks could have greater consequences to health, safety and the environment.

Distribution pipelines deliver natural gas directly to customers and can cause serious injury if damaged by digging or excavating. The majority of buried distribution pipelines are not marked aboveground.

Therefore, whether you are planting a tree in the back yard or planning major excavation work, it's critical to have all underground utility lines in the work area or pipeline right-of-way located before you begin to dig - regardless of whether any type of pipeline markers are visible. It's the law, and, now, it's easier than ever to comply. Just dial 811. Your call to 811 starts the process of having the underground utilities located and marked with bright safety paint and/or flags.

Always call 811 before you dig to prevent serious injury and property damage.
