2022 Water Master Plan

In 2019, the City of Corvallis embarked on an update to its Water Master Plan. The goal of the update was to bring together three older master plans (representing the three major components of the water system) into one comprehensive plan. Water Master Plans are required by the state to address future needs of the water system, which must follow all State and federal drinking water standards. Such plans typically look 20 years in the future to anticipate needs and challenges. The new master plan was completed in late 2021 and adopted by the City Council in 2022.

Water Distribution and Treatment Facilities Master Plan

Our Water System

The City's water system includes two water treatment plants that draw raw water from the Willamette River and the Rock Creek Watershed on the east side of Marys Peak. The system also includes 252 miles of distribution pipe, as well as pump stations, fire hydrants, and water meters. The entire system has a value of more than $350 million, representing a significant infrastructure investment for the Corvallis community. The Water Master Plan provides a framework to ensure the health and stability of that system for future generations.

Public Involvement

The Water Master Plan update was a multi-year effort involving public outreach, data analysis, and strategic planning. Most of the process was guided by regulatory requirements from the Oregon Health Authority, but the City also evaluated several other areas of operation, including disaster resiliency, intake options at the Taylor Water Treatment Plant, and the effects of climate change on the water system.
