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.
