Sammamish Plateau Business Survey  

For over 50 years, King County Wastewater Treatment Division (WTD) has collected and cleaned wastewater for the Puget Sound region. Operating a regional system allows WTD flexibility to adapt our service to meet community needs as our region grows. Now, WTD is working to send more wastewater flows from the growing Eastside to Brightwater Treatment Plant in Woodinville. The Sammamish Plateau Diversion Project will help make that happen.  

Our team is currently doing a lot of research as we develop project options. As part of this work, you may see teams in the field carrying out research. These activities may create temporary traffic delays or other disruptions in the project area. Eventually, your community will see a larger scale construction project that will have impacts in the area.

As we look at options, we want to connect with our business neighbors.

Let us know how we can serve you!

We invite you to complete our business survey by mid-December, 2024. We expect that this survey will take about ten minutes. We want to meet your needs for information and participation and hear your thoughts and concerns related to future construction and potential impacts to your business activities. This survey will help the project team understand how to best work with you and your employees.
