PIERCE COUNTY — A sewer interceptor is a sewer trunk 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.
To address 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. 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. Here is the project link if you want to sign up for updates.
The Parkland/Brookdale Interceptor is one of Pierce County’s largest sanitary sewer pipelines in a network of sewer pipes and pump stations that convey wastewater from unincorporated Pierce County to the Chambers Creek Regional Wastewater Treatment Plant.
The Parkland/Brookdale interceptor collects wastewater from other sewer mains and interceptors serving the majority of the Pierce County Sewer Service area south of 112th Street East between the eastern boundary of Joint Base Lewis McChord and the plateau west of the Orting valley.
The interceptor starts near the intersection of 13th Ave Court East and Brookdale Road East and continues northwest to its connection to the Spanaway Loop Bypass Interceptor at the intersection of 116th Street South and Spanaway Loop Road South.
- This project is the third of multiple phases necessary to increase the capacity of the Parkland/Brookdale Interceptor.
- A 72-inch interceptor will be constructed to 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.
- Construction start: Summer 2022.
- Future phases will continue the 72-inch interceptor to the connection point at the Spanaway Loop Bypass Interceptor at the intersection of 116th Street South and Spanaway Loop Road South
