Project
Duwamish Materials Recovery Facility
Stormwater treatment for a materials recovery facility that discharges to an impaired waterbody
This facility processes various recyclable materials and sees high truck traffic. It discharges to the Lower Duwamish, a 303(d)-listed impaired waterbody.The lack of available space onsite was a key factor in the design of this stackable multi-media treatment system. The system takes up roughly one parking stall, and it has relatively low O&M costs compared to an active treatment system. Since the installation of the treatment system, this facility has achieved consistent attainment on all applicable ISGP parameters.
Gallons treatedThe passive stacked media filtration system is a one-of-a-kind semi-passive filtration and adsorption treatment system. These systems are built to suit the project, and are designed to operate in two parts to allow for an options-based treatment train while providing easier system maintenance.
The system can be utilized for different applications and can be incorporated as water storage, media adsorption tanks, or up-flow treatment.
