Parkland/Brookdale Interceptor Future Phases

Update


Aug. 13, 2021

This future project is in the preliminary design phase, and the alignment of the sewer system and roadway impacts are in the process of being finalized. In the meantime, we are installing groundwater monitoring wells starting mid-August to better understand seasonal groundwater trends that may impact the future construction timeline. Installation of the groundwater monitoring equipment will be completed this fall. Staff will continue to monitor the groundwater levels until construction of the project begins.

About the project

This project is the final of multiple phases necessary to provide increased capacity for the Parkland Brookdale Interceptor. 


To address that capacity need, and to build a system that will last well into the future, Pierce County is continuing the 72-inch interceptor from the completion of Phase 3 to the connection point at the Spanaway Loop Bypass Interceptor at the intersection of 116th Street South and Spanaway Loop Road South.

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.

What does this mean for me?


Benefits

This project will increase the capacity of the existing interceptor to handle growth beyond 2024. It also replaces aging infrastructure with materials that are less likely to corrode, and so will last longer in the wastewater environment.


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.
