Telefónica Tech drives IoT smart water roll-out for Aguas de Cádiz

Telefónica Tech drives IoT smart water roll-out for Aguas de Cádiz is profiled by BTW Media because public-source evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Telefónica Tech is connecting more than 4,000 water meters in Cádiz to its Smart Water platform using NB-IoT technology.
• The project creates a stable, long-term, low-risk revenue model for utilities through hourly data, remote management and predictive analytics.

What happened: Telefónica Tech transforms public utility metering into an IoT-based service offering

In a major step in public utility digitalisation, Spain’s municipal company Aguas de Cádiz has recently engaged Telefónica Tech, the digital business unit of Telefónica, to convert more than 4,000 conventional water meters into connected smart meters. This initiative, part of the WATERCOG-PC project under Spain’s Ministry for Ecological Transition and Demographic Challenge and financed by NextGeneration EU funds, uses NB-IoT (Narrowband IoT) to enable continuous remote data transmission.

Telefónica Tech’s Smart Water solution, developed in collaboration with meter manufacturer Contazara, supports remote operation with low data and energy usage, ensuring battery life of at least 12 years. The smart meters send hourly consumption data to a cloud-based platform for processing and analysis, replacing traditional bi-monthly or quarterly readings.

The digital transformation begins with a pilot phase in a selected neighbourhood, homeowners’ associations and public services such as park irrigation. Following evaluation, the city-wide rollout will proceed in phases.

Why it’s important

For technology companies and utility service vendors, this project exemplifies how IoT can underpin long-term, stable revenue models in public utilities rather than one-off build-out contracts. By moving from periodic manual readings to continuous, automated data flows, utilities like Aguas de Cádiz gain a predictable information stream that can be monetised through service contracts, analytics, maintenance automation and improved customer billing accuracy.

The combination of remote metering, data-driven management and low-power connectivity reduces operational risk and creates recurring income streams for platform providers and operators. In contrast to traditional infrastructure investments, these IoT-enabled services tie technology adoption to measurable business outcomes such as leak detection, infrastructure failure anticipation, anomaly detection and precise billing, making them attractive for both public stakeholders and private sector partners seeking sustainable digital utility engagements.

For technology integrators, network providers and analytics vendors, projects of this nature signal that public utilities are becoming strategic clients for IoT and managed services, driving recurring revenues and enabling long-term commercial relationships.
