The near neighbor survey includes feedback from the people who live and work near our three regional treatment plants: West Point Treatment Plant in Seattle, South Treatment Plant in Renton, and Brightwater Treatment Plant north of Woodinville.

The survey is conducted by an independent research firm that randomly polls businesses and residents in each community.

Questions enable respondents to describe their perceptions of our plants and to share both positive and negative opinions about how they're operated. People also have an opportunity to rank the county's priorities and offer suggestions on how the county can improve.

The survey helps us understand how we're meeting our values of customer service and to give our neighbors a chance to tell us how we measure up to community standards.

WTD used to conduct the survey annually, and made a decision in 2007 to do it every two years as a cost-saving measure. We will commission the next survey in 2019.
