New acoustic system efficiently locates escaping water in pipes, removing the need to prioritise massive investment in meters

See https://www.economist.com/news/science-and-technology/21741134-saving-millions-litres-using-ai-trace-leaking-pipes

Geophones for detecting leaks in water pipes required very sensitive hearing by their operators. The linked article describes how a pilot version of a new AI acoustic system named Fluid https://stattus4.com/pt_BR/fluid/ * in use at 10 water companies identifies leaks in a fraction of the time it takes with geophones alone.

Given the huge volumes of water leaking from Irish Water's pipes, Fluid should achieve major cost savings by quickly identifying leaks and removing the need to prioritise massive investment in meters.

Maybe the real purpose of metering was more about facilitating a tax grab,not water conservation.

*Need Google Translate as in post number 3 below.

Their website is in some form of barbarian-speak:

Google Translate limited the length of translation of the description below:

Automatic detection system of network water leaks and distribution branches. It is based on an artificial intelligence system that, through the samples collected by the mobile collector, can analyze the data and classify them as leak / non-leak.
The manager has access to the dashboard, which enables the real-time monitoring of field scanning work and access to managerial reports. You can check the route taken by the data collector operator, access sample audio for system effectiveness auditing, and receive field data reports.
Automatic data analysis
No interference from external noise
Real-time tracking
More data for decision making
Less water withdrawn from springs
Increased service capacity
Does not have the need for a geophonist to be operated on
Water loss
According to the National Sanitation Information System (SNIS), the national index of treated water losses in distribution is 36.7%. In 2013, when losses were 37%, Instituto Trata Brasil estimated the volume of treated water lost in the country at 6.5 billion cubic meters per year, which gives 6.5 times the total storage capacity of the Cantareira system , in the state of Sao Paulo. It's enough water to supply 50 million people for a year. Sold, this volume represents approximately R $ 8 billion in damages annually.
Fluid combats so-called "physical losses", that is, leakage water losses corresponding to 60% of the total volume of losses in Brazil.
Cases
Fluid has been tested and approved by some of the country's major water distributors, including Águas de Votorantim, SABESP Jundiaí / Capivari, and ARES PCJ (in Santa Bárbara d'Oeste). In all cases, the system presented an assertiveness equal to or greater than the traditional scanning method in the shortest time, in total more than a thousand water meters and around 20 leakages were verified.
In the city of Votorantim, approximately 600 branches of a DMC were surveyed, where network and branch leaks were found, confirmed by the distributor's geophonist. In the city of Santa Bárbara d'Oeste, two hydrometers with high probability of leakage were pointed out. When repairing the first leak, the DMC's loss ratio fell from 41% to 18%.

If this system operates like other comparable existing tracing systems it will be only be useful when you know there is a leak that you need to look for.
In other words metering tells you that there is a leak at a particular address or on a particular line. Then you use this to pinpoint the exact location.
In that case you still need meters to tell you that there is a leak.

Otherwise would this not be like the health system running a scope into the veins of every person in the population every 3 years to see if they had a heart blockage, rather than just checking blood pressure and cholesterol etc for everyone and only scoping the small percentage where those checks identify a problem?

Would you not still need meters to identify when and where to use this system, otherwise it would be incredibly labour intensive and wasteful?

Well thank God that wasn't available 3 years ago or it would have been difficult to bury €500m worth of meters in the ground never to be used.

Acoustic leak detection has been around for a lot longer than 3 years.
See Domestic - Lowflo
This system may add a bit of software to process the signals but that too is not exactly ground-breaking.
Calling it AI is what makes it so 2018.
I do hope that they upload all the data to the cloud.............

That would really "close the loop" on water leaks :D:p

The increased speed of the AI system allows mapping of leaks in an entire water system on a far bigger scale than before.
