Detecting Water Leaks

LVVWD leak investigation vehicle

The Water District actively seeks out
leaks to reduce water waste.

Just as customers find and fix leaks in their homes, the Water District is vigilant in stopping leaks in the water distribution system. With more than 4,500 miles of pipe in our network, locating these leaks can be a daunting task.

To find and prevent leaks, LVVWD employs more than 8,000 leak detection units within the Water District's service area. The devices record sustained sounds or vibrations that may be caused by water seeping from the system.

These small two-pound listening devices are magnetically attached to underground water valves. Each night, the units "listen" for sounds of a leak. This information is sent to a receiver module mounted to district vehicles.

LVVWD crews patrolling the valley collect the data to help identify suspected leaks, which are then pinpointed with additional listening equipment.

Early Detection Saves Water

With the Permalog leak detection technology, surveying for leaks is quicker. Leaks are found and repaired before they surface on streets.

The leak detection transmitters are critical in water conservation efforts. Since 2004, LVVWD has detected more than 1,600 underground leaks using Permalog and estimates that the technology has saved 890 acre-feet of water (more than 290 million gallons).
