Communication Control Box Improvement Project

Construction is complete on an Environmental Services project that modified and installed communication control boxes (CCBs). These electrical panels are located throughout Portland to collect flow rates and other information needed to maintain the sewer system (see diagram).

CCBs can detect problems in the sewer system and alert Environmental Services staff to take corrective actions. As the city upgrades sewer pipes, monitoring points may move and new monitoring points may be added. These improvements will help prevent combined sewer overflows to the Willamette River. Enhancing our system technology protects water quality and public health.

Over the course of this project, many neighbors have contacted us to ask questions, report concerns, and provide general comments and feedback. Thank you for your involvement and cooperation during this important project.
