The natural gas system in South Tacoma had reached its capacity. The new line increases our natural gas system's reliability, as well as accommodates current and future growth in west Pierce County and surrounding areas. PSE's natural gas system works as a large network; any main line upgrade helps stabilize the system in adjacent communities as well as the entire geographic area.

Gate and Limit Stations

Gate and limit stations are devices in our natural gas transmission and distribution system that regulate the pressure of the natural gas. Specifically they decrease the pressure of the natural gas for use in residences and business.

How does natural gas get to my home or business?

Natural gas is a fossil fuel composed almost entirely of methane. Interstate pipelines transport natural gas to regional utility natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses. More than one-third of all Washington state households and businesses use natural gas.
