Non-revenue water recovery and leak detection in Anapra, Mexico

In this project, Idrica played the role of contractor, and provided the crews and the five technological leak detection solutions, including the acoustic equipment, the geophone, the correlator, the multipoint correlator, the tracer gas, and the endoscopic camera.

The main constraints encountered when detecting NRW were:

• Unpaved streets 
• Non-identified network lines
• Social problems at the border
• Around 80% of users did not have a meter or a micro-metering system.
• Users were connected to a network or to a network extension which were not recognized by JMAS Juárez.

This project showcases Idrica’s expertise in leak detection using helium tracer gas, a technique that has proven to be highly effective in locating leaks that are not detected using acoustic methods. 

Thanks to the non-visible leak detection program, the client located 140 leaks in six weeks, with an average distance of 0.5 km between them. This benefited over 20,000 people and saved 148,000 liters per day.
