About Oregon City Wastewater Division
- Protects public health by complying with sewage collection system environmental standards
- Maintains, plans, and improves the wastewater collection system, including 22 pump stations, 100 miles of pipelines, and over 2,000 manholes
- Implements best management practices while performing operations and constructing improvements to protect the surrounding environment
In addition to maintaining the current collection system, the Sewer Division helps Engineering Services provide capital improvements that replace deficient pipes and equipment and add system capacity or increase level of service to accommodate a growing population. The Wastewater Master Plan and its CIP identifies and prioritizes needs and construction projects that are funded by sewer utility fees and System Development Charges (SDCs) (collected when building permits are issued). Projects are implemented that protect natural resources and complement the surrounding environment.
Oregon City’s collection system transports our wastewater to the Tri-City Service District water pollution control facility (treatment plant) that is operated by Clackamas County Water Environmental Services (WES).
