Conference Agenda

Piece County Tour 1:00pm - 2:00pm

Pierce County’s Cascadia Wastewater Treatment Plant is a state-of-the-art MBR facility, serving the Employment Based Planned Community of Tehaleh in Bonney Lake Washington. Currently operating in the midst of a phased construction plan, the plant treats an average of .35 MGD to the highest standards in the Pacific Northwest, with plans for much more!

Some of the unique highlights of Cascadia include: 

• • A phased approach to construction that provides capacity as the community is built out.
  • Microdyne Flat sheet membranes producing superior effluent quality.
  • Currently operating with liquid stream processes only.
  • Built with a public/private partnership that provides an innovative solution to construction and operation issues. 
  • Intended as a closed loop community.   

Follow along with Jon Kercher as we tour the facility and learn more about what makes Cascadia and Tehaleh unique.
