LVVWD Leak Detection
The Water District actively seeks out
leaks to reduce water waste.
With more than 4,100 miles of pipe, locating leaks in the Las Vegas Valley Water District's (LVVWD) distribution system 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 1,300 underground leaks using Permalog and estimates that the technology has saved 3,336 acre-feet of water (more than 109 million gallons).
