A Las Vegas Valley Water District leak detection van

Stopping leaks in the water distribution system

With more than 6,500 miles of pipe in the Las Vegas Valley Water District network, locating leaks in the valley’s water system can be a daunting task.

To help track leaks down before they become a problem, the Water District uses an acoustic leak detection system that "listens" for water leaking underground and pinpoints where leaks are occurring.

This system is critical to water conservation efforts. It has led to the discovery of more than 2,500 underground leaks and saved more than 665 million gallons since 2004.

Would you believe us if we said we can see underground? This guy can!

Need to report a leak?

Call Customer Care at 702-870-4194 to report potential water system issues, including suspected leaks from water mains, service lines, valves, meters and public fire hydrants.

What happens after a leak is reported?

Emergency vs. non-emergency leaks

Once first responders from the district investigate reported leaks, they are classified as emergency or non-emergency, depending on:

  • The leak’s nature and severity.
  • The level of hazard posed to the general public.
  • The risk of potential damage to property or roadways.
  • Impacts to traffic and/or customers.

In the Water District service area, emergency leaks result in an immediate response for repairs. Non-emergency leaks are subject to different protocols and procedures in accordance with state laws.

Underground utilities are marked

Before repairs can begin, local utilities are mandated by Nevada law to locate and mark underground infrastructure.

The district will submit a “Call Before You Dig” request to have gas, power, sewer and communication lines marked. This protects underground utility lines from damage and helps ensure public safety, as well as the safety of utility workers.

For emergency repairs, this process is expedited and lines are marked within hours.

During non-emergency repairs, the process—by law—requires a minimum of 48 business hours to complete line locations.

System leak repairs are scheduled daily and may occur after hours to minimize impacts to customers and the public.

When will the street be repaired?

After all water system repairs are complete, district crews will temporarily patch the roadway to restore travel lanes.

The district’s asphalt contractor will install the final asphalt patch and repair sidewalks or curbs within the next three to six months in accordance with city and county standards.
