B Street Interceptor Phase 3

BStreetMap-V1 Opens in new window

About the project

This project is the third of multiple phases to install new gravity sewer pipeline near Mountain Highway East to serve the growing population of the south Pierce County community. 

The project will extend sewer access to unsewered properties, encourage further development in the Spanaway Basin area, and provide capacity relief to other sewer mainlines in the area.

Pierce County will be installing approximately 5,500 feet of sewer interceptor pipes along B Street East from 192nd Street East to Hidden Village Drive/10th Avenue East (near the Walmart entrance).

The connection between Ellis Lane East and 8th Avenue East will cut across a Pierce County property and easement.

What is a sewer interceptor?

 A sewer interceptor is a major sewer line that receives wastewater flows from multiple collection lines. These could be main or trunk sewers, or force mains, or other kinds of sewer lines. This combined flow is then directed to a wastewater treatment facility or another interceptor.

Project Updates


Aug. 1, 2023

After 10 months of work, crews wrapped up the B Street Sewer Interceptor Phase 3 project this week in Spanaway. They spent the past few weeks repaving and placing road markings throughout the construction site. Crews will return to the area in September to plant grass seed where required.

What does this mean for me?


Benefits

The project will extend sewer access to unsewered properties, encourage further development in the Spanaway Basin area, and provide capacity relief to other sewer mainlines in the area.

Homeowners

Pierce County will maintain existing sewer connections and make connections to the new interceptor where applicable. Pierce County will maintain service in the area without interruption by bypassing existing sewer flows.

Traffic impacts

Intermittent road closures will be necessary to complete the work. The contractor will be required to provide advance notice of any closures and maintain local and emergency vehicle access.

Privately owned property in County right-of-way 

The contractor will need to make use of the county right-of-way to install the sewer line. Property owners may need to remove privately owned items within the right-of-way that they wish to salvage prior to construction.
