Waste Water Treatment Plant

Waste-Water-Treatment-Plant-Aerial-View

 The plant was rebuilt and upgraded in 2014 to include modern waste water treatment technology, a new odor control system and increased capacity from 2.5 million gallons a day to 4 million gallons a day to accommodate Wilsonville’s continued growth. The facility’s effluent discharged to the Willamette River will be both cooler and cleaner, providing environmental benefits for aquatic life and downstream water users.
 
The city contracts with CH2MHill for operation of the waste water treatment plant, located at 9275 Southwest Tauchman Road.
