Advanced Leak Detection Program: Finding Leaks and Saving Water

SJW employees working on a fire hydrant in front of a home.

Preventing water loss from our underground pipelines helps San Jose Water protect water resources and promote sustainability in our community.

We currently deploy the Echologics Echoshore-DX cellular fixed leak monitoring system, which uses acoustic technology to locate leaks throughout the system. By placing sensors on fire hydrants, the sounds generated by leaks on pipes up to 12 inches in diameter can be detected and analyzed. Other technologies are used to support our technicians as they pinpoint the location of leaks in the field.

“Absolutely wonderful. Explained everything to me in detail. After leak was found, followed up with complete details so I could get it fixed. I think this is a fantastic service. Not only did it find a major leak on my property, it saved me money and saved a lot of wasted water. The Field staff were so professional and incredibly courteous.”
