Everything we do at Clean Water Services aims to protect public health, while enhancing the natural environment of the Tualatin River Watershed.
We are a water resources management utility that combines science and nature to clean water and return it to the Tualatin River so it can be used again. We work in partnership with others to safeguard the river’s health and vitality, ensure the economic success of our region, and protect public health for more than 600,000 residents and businesses in urban Washington County, Oregon.
In conjunction with 12 partner cities, we provide sewer and Surface Water Management (SWM) to over 600,000 people in the urban areas of the Tualatin River Watershed (PDF), which closely follows the urban growth boundary.
The partner cities are Banks, Beaverton, Cornelius, Durham, Forest Grove, Gaston, Hillsboro, King City, North Plains, Sherwood, Tigard, Tualatin, small portions of Lake Oswego, small portions of Portland, and portions of Clackamas and Multnomah Counties.
