Rancho Palos Verdes Community Update Center
Last update: December 8, 2023, 8:15 am
While the ground near Portuguese Bend and in other areas within Rancho Palos Verdes has been shifting for decades, we have seen an increase in ground movement recently, particularly following the significant rainfall we received over the past year. In this same time period, Cal Water has seen an increase in pipe leaks—along with leaks in customer private water lines and other utility lines—in this area.
On this page, we will share updates on what we at Cal Water are doing to address leaks that develop on our water mains, mitigate the occurrence of future water main leaks, and support our communities in Rancho Palos Verdes.
What We are Doing
We are taking a multi-pronged approach to address leaks in this area both immediately and long-term. Current and recently completed projects and their status are listed below. Click the title of a project or leak report () for additional information. Leak reports will remain on this page for 48 hours after they have been resolved.
Current Projects/Leak Reports

Status: Construction in progress.
Summary: Cal Water plans to replace 7,000 feet of smaller main with larger-diameter main and install additional main.
Status: Currently in design phase.
Summary: Crew will be stationed in area, so we are closer and can respond more quickly to reported leaks.
