King County plans to site a new storm water treatment plant in the Duwamish area to improve the water quality and control the frequency of CSO events in the Brandon and Michigan basins. The key objective of this project was to determine to best possible alternative for conveyance routing and treatment station siting while reducing CSO frequencies.

UrbanTech has provided engineering services to assist with the analysis of 5 alternative treatment site locations and 3 alternative outfall locations.  Our analysis assistance included combined sewage conveyance alignments and diversion locations for 5 alternate treatment station siting locations.  UrbanTech is currently working on the site Demolition and conveyance 30% designs.
