In 2004, the City of Newberg (City) contracted with Brown and Caldwell to develop a Facilities Plan to provide recommendations to the City’s Capital Improvements Program (CIP) for the City’s wastewater treatment plant (WWTP). The purpose of the Newberg WWTP Facilities Plan Update is to provide the planning for required modifications to meet projected growth within the urban growth boundary (UGB) and the urban reserve area (URA) to maintain compliance with its National Pollutant Discharge Elimination System (NPDES) permit and potential future regulations.

The City owns and operates a secondary WWTP located at 2301 Wynooski Road, Newberg, Oregon. The City currently provides wastewater collection and treatment services to its residents, commercial establishments, institutional customers, and a number of industries. Sewer service is provided only to customers within the city limits, with the exception of a few residences outside of the city and SP Newsprint Company, which discharges only domestic wastewater to the municipal system.
