Join us to learn about the Recycled Water Project taking place in the Sammamish Valley and how this water source may serve as a vital tool to protect rivers and streams throughout Washington as this region faces increasing demands and climate change stressors. Presenters will include: Washington Water Trust and University of Washington Associate Professor Ed Kolodziej.

A panel presentation about the Sammamish Valley Recycled Water Project will be held on Wednesday, April 7th, virtually via Zoom, as part of the on-going series of Community Education programs presented by the Sammamish Valley Grange in Woodinville.

The Sammamish Valley Recycled Water Project seeks to expand the use of recycled water in the Sammamish Valley, which is home to some of the most productive agricultural lands in the state and the King County Brightwater Treatment Plant. In collaboration with Washington State University Puyallup Extension and King County Wastewater Treatment Division, Washington Water Trust is conducting a recycled water pilot study in the Sammamish Valley, designed to investigate recycled water as an irrigation source and assess its safety on edible food crops.

Recycled water is already used nationally as a sustainable water source to irrigate edible food crops but is underutilized and underdeveloped in the Valley and Washington state. This project seeks to identify perceptions and address any concerns about using recycled water to irrigate. Ultimately, the benefits of using recycled water for irrigation would allow more water to stay in the Sammamish River by reducing river diversions, protecting salmon and other wildlife that depend on cool and clean water.

Perhaps you have heard the term “Recycled Water” but are not sure what it is, have concerns about its use, or want more details on how using it could lead to protecting salmon. The panel presentation will feature project staff and provide an overview of the project, study design and methodology, as well as the beneficial environmental outcomes.

Ed Kolodziej is an associate professor at the University of Washington with joint faculty appointments at Environmental Sciences at UW-Tacoma and in Civil and Environmental Engineering at UW-Seattle. He also is a Principal Investigator at the Center for Urban Waters (Tacoma, WA) where Ed and his research group use advanced mass spectrometry and hard work to investigate contaminant fate and transport, build effective treatment systems, and insure ecosystem health.
