Pierce County built a new eductor waste decant facility adjacent to the Central Maintenance Facility in Frederickson in 2014.
The facility allows the county to separate, process, reuse and dispose of liquid and solid waste generated when road crews clean catch basins, ditches and drainage pipes located in unincorporated Pierce County.
Waste is transported from job sites back to the facility in vactor trucks. It is then emptied into the facility and processed. The resulting processed water is used to wash maintenance trucks, while the solid waste is reused as a soil amendment or transported to a solid waste facility.
This new facility increases Pierce County's capacity for processing waste from the storm drains, and is more cost effective and efficient since the facility is home base for most of Pierce County's road crews and in an area where most of the county's storm drains are located.
The new facility was built on a storage and stockpile area, and has a footprint of approximately two-and-a-half acres.
