Williams’ Northwest Pipeline is a major transporter of natural gas in the Pacific Northwest. In fact, Williams delivers nearly 90 percent of the natural gas consumed in the state of Washington, heating homes and for use in generating electricity.

The Northwest Pipeline system has changed significantly since its beginnings nearly 60 years ago. What began as a 1,500-mile pipeline is now a 4,000-mile bi-directional transmission system crossing the states of Washington, Oregon, Idaho, Wyoming, Utah and Colorado. Northwest’s bi-directional system provides access to British Columbia, Alberta, Rocky Mountain and San Juan Basin gas supplies.

State of Washington

 Northwest Pipeline has 1,309 miles of natural gas transmission pipeline in the state of Washington with 13 compressor stations. Our three largest customers in Washington are Puget Sound Energy, Avista Corporation and Cascade Natural Gas.



Pipeline Safety

Pipelines are the safest, most reliable and efficient manner of transporting energy products. Pipelines exist almost everywhere throughout the United States — generally buried underground — transporting the energy that you depend on every day. At Williams, we understand that we have a responsibility to our neighbors and the communities along our pipelines to embrace pipeline safety by implementing stringent safety programs and practices every step of the way.

This video demonstrates how we keep our pipelines and the surrounding communities safe.
