BACKGROUND
The upper reaches of the Newhope-Placentia Trunk Sewer carry flows from the cities of Brea, Fullerton, Placentia, and Anaheim to Plant No. 1 for reclamation. The Newhope-Placentia Trunk Replacement, Project No. 2-72, increases the capacity of the trunk sewer to satisfy current and future flows, allows abandonment under a subsequent project of the Yorba Linda Pump Station, and adds flexibility to the collections system to divert reclaimable flows to Plant No. 1.
In May 2018, a Construction Contract was awarded to Group OHL USA, Inc. for Newhope-Placentia Trunk Sewer Replacement, Project Nos. 2-72B and 2-72C. The contract replaces four miles of pipeline within sensitive areas along State College Boulevard, including Anaheim's Platinum Triangle, and business and residential areas. The work includes traffic control sequencing, deep excavations, multiple shifts, sewer bypassing, pipeline abandonment, four trenchless jack and bore crossings through major arterial streets and railroads, and sewer pipe crack repair work on the Rolling Hills Sub-Trunk. The pipeline work is complete with the paving and restoration work scheduled to be complete by the end of September. Only pavement striping and punch-list work will remain outstanding to be completed at the beginning of October. At the time of award, the work was scheduled to be complete in February 2021, however, due to construction delays, it is expected to be substantially complete in October 2021.
