Officials from the Department of Ecology presented Sewer Utility staff with the Outstanding Treatment Plant award for the Kingston and Manchester treatment plants on Monday, November 9, 2015, at the Kitsap County Commissioners meeting.

More than one-third of Washington’s wastewater treatment plants – 127 – have received an Outstanding Performance Award from the state Department of Ecology for perfect performance in 2014. When the awards program began in 1995, only 14 treatment plants had perfect compliance. One of these was the Manchester Treatment Plant, which has consistently received the award for 20 years in a row.

A special award was given to the Manchester Treatment Plant to recognize the milestone of 20 years of outstanding performance. Congratulations to all of our treatment plant operators for a job well done.
