Wastewater Treatment Services is comprised of Administration, Operations, Maintenance, Biogro, and Laboratory. There are 52 FTE in this division with an annual operating budget of approximately $9 million.
To meet or exceed the requirements of the federal Clean Water Act (CWA) and the Oregon Department of Environmental Quality (ODEQ) administration of these CWA rules.
The Willow Lake Water Pollution Control Facility (WLWPCF) and River Road Wet Weather Treatment Facility (RRWWTF) are responsible for treating the wastewater generated by the citizens of Salem, Keizer, Turner, and other unincorporated areas of Marion County served by the sewer collection system. Salem’s wastewater treatment service population is approximately 229,000 people. The performance of the facilities is measured on a daily basis through the collection and analysis of influent and effluent samples. The results of the analysis confirm compliance with the operating permit regulatory standards. These standards are designed to protect in-stream water quality and the health of the organisms living in and around the Willamette River.
The maintenance department executes an aggressive preventative maintenance program to keep existing and new equipment at WLWPCF and RRWWTF operational and reliable. Upgrades and enhancements to the Electrical, Mechanical, and Distributed Control System (DCS) have significantly improved both facilities.
The Biogro program ensures that all 34 million gallons of biosolids (primarily organic product produced from the wastewater treatment process) produced at WLWPCF are beneficially reused in an environmentally sound, publically acceptable and cost-effective manner consistent with all state and federal biosolids regulations and management practices.
The laboratory analyzes samples supporting many programs throughout the City including, wastewater treatment, water treatment and distribution, industrial billing and pretreatment and stream and storm water monitoring. The laboratory is Oregon Environmental Laboratory Accreditation Program (ORELAP) accredited and performs many different types of analysis including, microbiological, metals, solids and nutrients.
