Pierce County announcement.
Pierce County is installing a new sewer interceptor in Spanaway near state Route 7/Mountain Highway East as part of the B Street Interceptor project.
This is the third phase of a multi-phased project to install new gravity sewer pipeline to serve the growing population of the south Pierce County community.
Project schedule
Road closures on work zone 3 will go into effect starting Monday, Oct. 24. During work zone 3, access to SR 7 from B Street East and Pirnie Road East will be closed. Drivers should use Field Road East as an alternative route.
On Wednesday, Oct. 26, the road closure for work zone 2 will go into effect, where B Street East between 192nd Street East and 196th Street East 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.
This project will consist of eight different work zones. Work hours consist of six 10-hour days per week, Monday through Saturday. There will be no work on observed holidays or on adjacent weekends when the holiday falls on a Friday or Monday.

About the project
Crews 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.
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.
A sewer interceptor is a major sewer line that receives wastewater flows from multiple collection lines, which is then directed to a wastewater treatment facility or another interceptor.
The construction work is estimated to cost approximately $11.5 million and is funded by revenue from connection charges and monthly sewer rates.
