A2A Ciclo Idrico
Brescia
A2A Ciclo Idrico, part of Italy’s largest multi-utility company, oversees 3,000 km of water pipes in Brescia and nearby areas, serving 1.5 million people. In 2019, A2A set a goal to reduce water losses by 40% and implemented Aliaxis’ AQS technology to detect leaks and lower energy consumption. During a pilot test in Brescia, 39 underground acoustic sensors were installed along 15 km of pipeline, identifying 10 hidden leaks within the first week. Following this success, A2A expanded the use of the AQS solution.
By 2022, 92 km of pipes were monitored, revealing over 170 leaks, and the repairs saved 1.4 million cubic metres of water annually, worth €560,000. By reducing the need to pump and treat excess water, the initiative also lowered energy consumption by 1 million kWh per year and reduced greenhouse gas emissions by 504,000 kg annually.
Water is a finite resource, and as global population growth, urbanisation, and climate change intensify, efficient water management becomes crucial. Even minor losses in water-scarce areas can significantly impact agriculture, industry, and the well-being of communities reliant on these resources. Globally, the estimated volume of non-revenue water — water that is produced but lost or unaccounted for — stands at 346 million cubic metres per day, amounting to 126 billion cubic metres annually. Valued conservatively at USD 0.31 per cubic metre, these losses represent a staggering USD 39 billion each year.1, 2
And when water leaks from distribution pipes, energy is lost twice.3
In Italy, approximately eight billion cubic metres of water enter the public distribution network yearly, yet 42% is lost due to leaks in ageing infrastructure, enough to supply 43 million people. While Europeans average 125 litres of water consumption per day, Italians consume nearly double that, up to 236 litres a day.4
A2A Ciclo Idrico is committed to reducing water loss and enhancing efficiency for more sustainable operations that align with European standards. With AQS by Aliaxis technology, our continuous monitoring enables us to effectively address leaks in ageing infrastructure and strengthen the resilience of our water network, making significant progress toward a more sustainable future.
Tullio Montagnoli, Managing Director at A2A Ciclo Idrico
AQS by Aliaxis uses fixed acoustic sensors and mobile devices, integrated with AI, for advanced leak detection. Independent of pipeline type, it detects leaks above or below ground, generating alerts with precise locations. Field teams are then dispatched to repair leaks based on these accurate alerts.
