Newhalem, Diable Wastewater Treatment Plants Awarded for Perfect Performance in 2013

Seattle City Light's wastewater treatment plants in Newhalem and Diablo earned perfect scores and Outstanding Wastewater Treatment Plant Awards from the Washington Department of Ecology for 2013.

Seattle City Light’s wastewater treatment plants in Newhalem and Diablo earned perfect scores and Outstanding Wastewater Treatment Plant Awards from the Washington Department of Ecology for 2013.

“Treatment plant operators are professional who understandably take a lot of pride in their work and its importance in protecting the environment. It is an honor to recognize their contributions with these awards,” said Heather Bartlett, manager of Ecology’s Water Quality Program.

Award winning plants passed all environmental tests, analyzed all samples, turned in all state-required reports and avoided permit violations during 2013.

The Newhalem and Diablo plants at City Light’s Skagit Hydroelectric Project were among 126 plants that achieved a perfect score for 2013.

This is the sixth consecutive year the Diablo plant has earned the award, the second consecutive award for Newhalem and the 13th time both plants have been recognized since the awards were started in 1995.

About 330 wastewater treatment plants operate in Washington. When the award program began in 1995, only 14 treatment plants had perfect compliance.

A complete list of the award winners by county is available on Ecology’s website.
