Pam Elardo, WTD Director

Pam Elardo, King County Wastewater Treatment Division Director

In October 2010, Executive Constantine appointed Pam Elardo as the Director of the Wastewater Treatment Division in the Department of Natural Resources and Parks. Pam served as interim director following Christie True’s appointment to director of the Department of Natural Resources and Parks in July 2010.

With an impressive array of professional credentials and prior experience in the division, Pam is uniquely poised to manage WTD’s 600 employees as well as an operating budget of $108.9 million and a capital budget of $219.1 million.

Pam most recently served as manager of the West Point Treatment Plant, which is the largest wet weather treatment facility on the West Coast. Prior to that, she oversaw the division’s Asset Management Program and worked in the division’s Capital Program as a supervisor of the Permitting and Right-of-Way group during the planning and design of the Brightwater Project.

Before coming to King County, Pam worked with the Washington State Department of Ecology for 14 years.

In addition to her educational credentials, which include master’s degree in environmental engineering as well as a bachelor’s degree in chemical engineering, Pam is a licensed Professional Engineer (PE) in the state of Washington and holds certification as a Group IV Wastewater Treatment Plant Operator.

What truly makes Pam unique is her personal passion for water quality that began long before she started her career with King County. Pam taught math and science in Thailand and served in the Peace Corps in Nepal as a sanitary engineer that supervised a team of workers constructing water supply systems. She also runs a small non-profit organization dedicated to village-level community development and water resource projects in developing countries.
