North Seattle Delivery Lateral Expansion Project
North Seattle Delivery Lateral Expansion Project
The North Seattle Delivery Lateral Expansion project is being constructed by Williams to meet Puget Sound Energy’s growing demand for natural gas in the greater Seattle area.
Project Description
The project involves removing the existing 8-inch diameter pipeline between milepost 0.00 and 2.2 on Northwest’s North Seattle Delivery Lateral Expansion and replacing it with new 20-inch diameter pipeline within the existing right of way and upgrading the existing North Seattle meter station.
These infrastructure improvements to Northwest’s system will increase the delivery capacity on the North Seattle Delivery Lateral by 84,200 Dekatherms per day.
