This project is the third of multiple phases necessary to provide increased capacity for the Parkland Brookdale Interceptor. The existing 36-inch sewer interceptor between phase 2 and the future interceptor phases is expected to reach its capacity by the end of 2024. To address that capacity need, and to build a system that will last well into the future, Pierce County is constructing a 72-inch interceptor that will convey wastewater from the intersection of 131st Street East and A Street South to an existing sewer interceptor at 129th Street South and C Street South. See map below.
Future phases of the project will address other capacity issues in the existing system.
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.
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.
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.
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.
