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.

Traffic Impacts

Intermittent road closures will be necessary to complete the work. During the road closures, the road will be closed for through traffic. Access for local traffic and emergency vehicles will be maintained at all times. Detour signs will also be placed for drivers and pedestrians.

Jan. 13, 2023 Update

Road closures for phases 2 and 3 have been lifted for the B Street Sewer Interceptor project in Spanaway. B Street East between 192nd Street East and SR 7/Mountain Highway East and access to Pirnie Road East from SR 7/Mountain Highway East are back open to all traffic. Crews will still be working in the area in the coming weeks, so please continue to travel with caution. 

 Road closure for the Phase 6 work will begin on Tuesday, Jan. 17, 2023. Eight Avenue East between SR 7 and 197th Street Court East will be closed during this period. Detour signs will be in place to direct drivers to an alternate route. Access for local traffic and emergency vehicles will be maintained at all times.

There will be no construction activities on Jan. 14 and 16 in observance of the Martin Luther King Jr. Day holiday.

The road closure for this phase will be in effect through Monday, Feb. 20, 2023. 

Hours of Work

The contractor will be working six 10-hour days per week, Monday through Saturday. There will be no work on observed holidays nor on adjacent weekends when the holiday falls on a Friday or Monday.

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.
