Did you know?
"SJW were super duper! They were kind, patient, helpful, knowledgeable and amazing!! ⭐⭐⭐⭐ Highly Recommend!"
“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.”
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.
This program offers several benefits:
- Identifies leaks before they become catastrophic
- May help prevent customer water bill increases from long-term leaks
- Helps prevent damage to customer property
- Reduces community disruption from unscheduled repair work
- Sustainably reduces water loss
- Protects the environment and wildlife from chlorinated water discharges
- Protects water quality
Acoustic Leak Detection
Acoustic leak detection sensors are placed on special fire hydrant caps. These sensors monitor sounds within our water system and identify acoustic anomalies, which indicate leaks. When acoustic anomalies are found, geographic information is automatically sent to our staff for further investigation. During further investigation, our staff more precisely locates leaks, usually with the leak correlator or ground microphone.
