The Orange Western Trunk Sewer Project is making its way to the City of Cypress. The regional sewer pipe on Orange Avenue needs to be rehabilitated. A segment of pipe between Valley View Street and Juanita Street will be relined, another segment will be replaced and the manholes along the pipe will be rehabilitated. To perform this work while maintaining service, it will be required to reroute the sewer flow which requires pumps to be placed above ground.
This work will enhance the condition of the pipe and allow it to remain in service for many years to come. In turn, the community will have a reliable regional sewer system they can trust.
