Project Background
The objective of the Project was to reduce the potential damage to, and post-earthquake recovery time of, the pipelines and the associated vault structures. The site is located on a slow-moving landslide known as the Penitencia Creek Landslide. Furthermore, the Hayward Fault runs in a northwest to southeast direction approximately 1.2 miles to the east of the site. During the past 40 years of operation, the slow creep of the landslide has impacted the structural integrity of the three pipelines.
The Project included replacement of approximately 865 lineal feet of each of three pipelines - the 66-inch diameter Penitencia Force Main, the 60-inch diameter Penitencia Delivery Main, and the 72-inch diameter South Bay Aqueduct, currently conveying raw and treated water to and from the Penitencia Water Treatment Plant with earthquake-resistant pipes. The Project also included installation of a new flowmeter, a new control building, and several pipeline vaults.
