We have gone virtual! The Education Team from King County Wastewater Treatment Division has turned our field trips, tours, and other programs into virtual experiences. For information, visit our virtual education offerings and resources.

The Wastewater Treatment Plants are currently operating as normal, 24/7. Following the guidance of Seattle-King County Public Health, all facility tours and in-person education events have been suspended and the Brightwater Center is closed until further notice. Please check back periodically for updates.

How can WTD support educators and remote learning?

King County WTD Education and Outreach is committed to doing what we can to support educators during this time. If you would like individualized educator support from our team, please fill out this SURVEY . Support could include additional remote teaching resources and virtual experiences. Once you have filled out the survey our Education and Outreach team will be in contact with you with 3-4 business days to start the conversation.

Only toilet paper belongs in the toilet. Do not flush anything else (even if it is labeled flushable). Flushable: wipes are not really flushable – they don’t break down and can cause expensive plumbing problems in your home and damage the sewer system. Put wipes in the trash. Learn more.
