Dec 12, 2019


If you’re looking for a public utility leader who’s respected by her peers for her leadership style, passion about water and engagement across the industry to effect change in water resources management, Diane Taniguchi-Dennis checks all the boxes.

As chief executive officer of Clean Water Services serving Oregon’s second-largest county, Taniguchi-Dennis embodies the modern utility executive. Her education and background in both environmental engineering and business management reflect the utility’s approach of combining science and nature to enhance Oregon’s Tualatin River Watershed.

“She’s a very visionary thinker about the potential utilities have for contributing to the environment as a whole,” says Pat Sinicropi, executive director at the WateReuse Association, for which Taniguchi-Dennis is treasurer and a member of the board of directors. “She likes to think outside the box but at the same time understands the practical realities.”

Clean Water Services is renowned for its achievements in resource recovery and serves about 600,000 residents in the urbanized portions of the Tualatin River Watershed, which stretches from small cities near the foothills of the Oregon Coast Range to the suburbs on the west edge of Portland.
