 For more information please contact the Construction Hotline at or at (657) 208-7900.

We started 2020 in full construction mode. We have installed about 60 percent of the pipe, as we continue to make progress on that front, we are also connecting all the laterals to the new sewer line to make sure service is not interrupted, and restoring the areas that are completed. It's a big job with a lot of puzzle pieces to put together so it takes quite a bit of time.  Take a look at all of our current activities below:

Project Description:

The project is replacing four miles of sewer along State College Boulevard from the SR-91 to Orangewood Avenue in the City of Anaheim. Construction began in late summer 2018 and is scheduled to be completed in 2020. Once the project is complete, eight million gallons of wastewater will be diverted to OCSD’s Plant No. 1 in Fountain Valley for treatment before being send to the Groundwater Replenishment System.  This is Phase B of a two-phase project; Phase A was completed in 2017 and took place from Yorba Linda Blvd. to SR-91 in the City of Fullerton.
