The City of Woodburn owns and operates a Wastewater Treatment Plant (WWTP) and Collection System located in the northern part of
Marion County. The Treatment Plant Facility is situated off Highway 211 on approximately 140 acres of land, east of Maclaren School
for Boys. The treatment facility is an Oregon Class IV System and the Collection System is an Oregon Class III. The wastewater
treatment plant provides primary, secondary, and tertiary treatment along with effluent reuse. Treated effluent is either discharged
to the Pudding River or irrigated to a poplar tree reuse system. The City provides secondary wastewater treatment from November 1
to April 30 and tertiary treatment with reuse from May 1 to October 31, depending on receiving stream flow.
Wastewater Treatment Plant & Poplar Tree Reuse System
The wastewater treatment plant operations includes activities and tasks that have the potential of affecting the public’s health
or the environment. Operator’s actions could change the treatment plant’s effluent or bio-solids quality. Operational activities
confirm process modes, change process modes, handle treatment plant products, and maintain product quality. The activities
directly determine effluent and biosolids quality that could affect public health. The activities use the majority of the
direct and indirect materials consumed at the POTW. Most POTW energy and chemical use is consumed in process control activities
at the treatment plant and lift stations. POTW operators operate the treatment plant, poplar reuse system, lift stations, and
force mains.
