Pipeline
Information
Important information about the natural gas pipeline in our community
The Deer Park neighborhood in Sammamish, Washington, is traversed by a 3,900-mile-long interstate natural gas pipeline operated by Williams Northwest Pipeline Corporation.
This pipeline runs through a 60-foot right-of-way that follows the greenbelt within Deer Park.
In 2006, Williams completed a Capacity Replacement Project, replacing a 50-year-old 26-inch pipeline with a new 36-inch line. The project began in March 2006 and was completed in November 2006, with the new pipeline going into service in December 2006.
Contact the Northwest Pipeline 24-hour Emergency Hotline:
If you suspect a gas leak or pipeline emergency, call immediately. Do not attempt to investigate or repair the issue yourself.
