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.

Value proposition

Awards and recognition
Awarded for our technological and sustainable impact

Best technological solution in urban water network management
Recognition for the project carried out with Canal de Isabel II for its impact on operational efficiency, sustainability, and citizen service.

Digitalisation of the water cycle with a sustainable approach
Award for the use of Microsoft Azure for environmental monitoring and advanced analytics in water projects.

Onesait Customers recognised as an outstanding solution
Included in Gartner’s Market Guide and implemented in more than 90 companies serving over 110 million customers.
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.

Trends
Discover the trends that are revolutionising the sector

Smart storage for a more resilient water network
New regulation on energy storage sets an important precedent for more flexible hydraulic infrastructures, enabling integration with renewable sources and improving system stability.

Artificial intelligence for more efficient water management
AI is driving the transition towards sustainable models, optimising water use, improving operational efficiency, and supporting decision-making with reliable, real-time data.

Prepaid water: efficiency, inclusion, and billing control
The prepaid model in water services reduces non-payment, improves transparency, and ensures fairer, more efficient access to this essential resource, especially in vulnerable contexts.
