Water Treatment Plant


In April 2002, Wilsonville began operation of its new water treatment plant on the Willamette River. The plant is capable of processing 15 million gallons per day (mgd). Within Wilsonville, demand for water varies seasonally from a low of approximately two mgd in the winter to nearly six mgd in the peak of the summer.

Emergency Reserves & Backups

The plant's additional treatment capacity is available to meet growth in demand. As further backup supply, the city's water system includes storage tanks throughout town with a total combined capacity of nearly 11 million gallons.

Wilsonville's former water supply (a system of eight local wells) is also available for use in emergencies. All of Wilsonville's storage tanks and wells are covered and have security systems in place. Operation of the water treatment plant is performed under contract by Veolia Water North America.
