An increasingly scarce resource, an increasingly demanding management
Water is a critical resource under growing pressure: prolonged droughts, contamination of natural sources, and rising demand. Added to this are new regulatory, social, and operational requirements that demand doing more with less.
In the face of this challenge, digitalising the complete water cycle — through sensorisation, automation, advanced analytics, and cybersecurity — has become essential to reduce losses, improve efficiency, and ensure a resilient and sustainable service.

Our impact
Real impact on operations, experience, and the environment

Operational efficiency and economic return
We digitalise assets and processes to optimise water management at every stage. Our solutions have made it possible to reduce operating costs in networks and plants by up to 30%, increase the availability of critical infrastructures by 15%, and automate processes with time and resource savings of up to 25%.

User experience and excellence in management
We improve citizen relations with digital, personalised, and multichannel solutions. Utilities have reduced claims by 50%, shortened the Meter-to-Cash cycle by 3 days, and increased collection rates by 20%, while also optimising internal process efficiency.

Environmental sustainability and service resilience
We apply advanced analytics to reduce losses, emissions, and consumption. Results include a 90% reduction in leaks in distribution networks, up to 40% less non-revenue water, and energy improvements in plants that translate into a smaller carbon footprint and greater service continuity.
