From Gold to Platinum, King County Wastewater Treatment Division is moving up the periodic table!

Each year NACWA recognizes member agency facilities for their dedication in maintaining compliance of NPDES limits. All of our plants are receiving awards this year, but we’re especially excited to announce that our Vashon Plant has now moved up the ranks from Gold to Platinum. Platinum Awards recognize 100% compliance with permits over a consecutive five-year period.

In other words, we’ve been following all the rules.

Check out our treatment plants below, including the awards they’re receiving!
