PPSU Pre-construction Activities Start Today in South San Francisco
Today the project contractor, Ranger Pipelines, Inc., will begin pre-construction activities for the Peninsula Pipeline Seismic Upgrade (PPSU) inside the San Francisco Public Utilities Commission (SFPUC)’s right of way in South San Francisco. Work will occur Monday through Friday from 7 a.m. to 5 p.m. Please keep an eye out for intermittent sidewalk closures and detours on Arroyo Drive and Westborough Boulevard.
The contractor will clear the project site of materials and brush within the right of way and begin potholing to locate existing underground utilities. The contractor will begin construction of a new tunnel across Westborough Boulevard in October 2014. The installation of the new pipeline from West Orange Avenue to Arroyo Drive will start in January 2015.
The PPSU project includes the seismic upgrade of three Hetch Hetchy regional water delivery pipelines located in Northern San Mateo County. This project will ensure the pipelines can continue to deliver water to customers after an emergency. For more information, please subscribe to this blog to receive project updates.
