Rancho Palos Verdes Community Update Center

Last update: December 8, 2023, 8:15 am

Cal Water truck in Palos VerdesWhile 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 (Reported leak icon) for additional information. Leak reports will remain on this page for 48 hours after they have been resolved.

Current Projects/Leak Reports

Installing temporary, above-ground water main in Seaview

Summary: We will install temporary, above-ground water pipes in a portion of Seaview.

Status: Construction in progress.

Installing 9,500 feet of new water pipes on Narcissa Drive

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.

Stationing personnel in Seaview 24/7

Summary: Crew will be stationed in area, so we are closer and can respond more quickly to reported leaks.

Status: Effective until further notice.

Utilizing leak detection technicians

Summary: Leak detection technicians are "on the ground" to survey infrastructure and listen for active, unsurfaced leaks.

Status: Crews have canvassed Seaview, Portuguese Bend Beach Club, Portuguese Bend Community Association, and other areas.

Investigating other pipe materials and/or construction methods

Summary: Newer materials/methods for water main replacements that may better withstand ground movement are being evaluated.

Status: Evaluation of materials and methods underway.

Walking Burma Trail

Status: Ongoing since September 8, 2023.

Elevating all leaks in Rancho Palos Verdes

Summary: We have been elevating all water main leaks in Rancho Palos Verdes to our "Code 4"—or highest—response priority, so crews respond to water main leaks as quickly as possible.

Status: Ongoing since early 2023.

Checking for leaks on your property

Leaks can also occur on customers' private water lines, valves, hoses, sprinklers, and pools. Here are some ways you can spot a leak on your property.

  • Yard leaks: Look for wet spots or patches of grass that are greener than the rest of your yard—these could indicate a leak in the pipe.
  • Broken sprinklers: Check your sprinkler system for any broken sprinkler heads or leaks.
  • Pool leaks: Keep an eye on the water level in your pool. If it's losing an eighth of an inch or more per day, there's likely a leak.
  • Unsure if you have a leak: Turn off the water inside and outside your home, and check your water meter. If the small leak indicator dial spins, water is still pushing through the meter. (Please note the meter lid is heavy; please remove carefully.)
