Parkland/Brookdale Interceptor Projects
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.
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.
Parkland/Brookdale Interceptor Phase 1 (Completed)
- This project was the first of multiple phases necessary to increase the capacity of the Parkland/Brookdale Interceptor.
- The existing 21-inch and 30-inch sewer interceptors were replaced with a 72-inch interceptor to convey wastewater in an easterly direction on Brookdale Road from 13th Avenue Court East to just past Golden Givens Road East.
- This project was completed in 2001.
- This project was the second of multiple phases necessary to increase the capacity of the Parkland/Brookdale Interceptor.
- The existing 30-inch interceptor was replaced with 72-inch interceptor and extended along a new alignment to facilitate Phase 3 of the project.
- This project was completed in 2016
- 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
The original interceptor was constructed in the 1980s as part of a series of Utility Local Improvement District projects that were sized and located to serve properties within the Utility Local Improvement District boundaries at the time of construction.
Nearly 40 years later, the original pipe is reaching the end of its useful service life. At the same time, the growth within the County is expected to eventually exceed the capacity of the existing facilities.
Over the last 20 years the County has been proactive in planning and implementing a series of projects to increase the capacity and extend the useful service life of the interceptor to ensure the sanitary sewer system works well for those who live in the County now, and in the future.
