Earthpulse deployed a satellite-based water monitoring system using high-resolution Sentinel-2 imagery from the European Union’s Copernicus programme. By combining Earth Observation data with AI-driven analytics, we transformed raw imagery into structured, actionable water quality indicators. The solution delivers scalable, continuous monitoring to support faster and more informed water management decisions. [Aigües de Manresa](https://www.aiguesmanresa.cat/) is the local water authority responsible for managing water resources in the Manresa region of Catalonia. Supplying drinking water to over 103,000 citizens, the utility must ensure high-quality water while responding to increasing environmental and operational pressures. To strengthen reservoir monitoring and support data-driven decision-making, Aigües de Manresa partnered with Earthpulse to integrate satellite-based water quality analytics into its operations. ![By Josep Renalias - Own work](https://www.earthpulse.ai/hs-fs/hubfs/Seu_Manresa_vista_general.jpeg?width=1280&height=851&name=Seu_Manresa_vista_general.jpeg) By Josep Renalias - Own work ## The challenge Monitoring water quality in reservoirs is a core responsibility for public authorities and an increasingly complex one. Climate variability, resource constraints, and operational demands make frequent, large-scale monitoring difficult. Traditional approaches rely on: - Manual field sampling, which is time-consuming and costly - Static sensor networks with limited spatial coverage - Fragmented data workflows that slow response times - Chlorophyll concentration - Turbidity levels - Dissolved organic carbon - Water extent These methods limit the ability to monitor water quality consistently across space and time, and to respond quickly to emerging risks. Aigües de Manresa needed a more scalable, automated solution that deliver reliable insights without increasing operational burden. ## Our approach Earthpulse deployed a satellite-based water monitoring system leveraging data from the European Union’s Copernicus programme, specifically Sentinel-2 imagery. The system have been used to monitor the Parc de l’Agulla reservoir in Manresa — a 0.64 km² artificial lake with a storage capacity of 200,000 m³. Copernicus data provides unmatched temporal consistency, wide spatial coverage, and high radiometric reliability making it ideal for water quality monitoring and long-term environmental management. #### Turning satellite data into operational insight The solution integrates advanced algorithms to transform raw satellite imagery into reliable water quality indicators, including: To ensure high data quality and usability, Earthpulse implemented: 1. **Automated cloud filtering** using AI (S2Cloudless model) 2. **Median filtering and interpolation** to clean time-series data 3. **Temporal extrapolation** to fill data gaps caused by atmospheric interference Beyond analytics, the system was designed with usability and confidence in mind. ![Screenshot 2026-02-20 at 17.12.18](https://www.earthpulse.ai/hs-fs/hubfs/Screenshot%202026-02-20%20at%2017.12.18.png?width=324&height=270&name=Screenshot%202026-02-20%20at%2017.12.18.png) Example of temporally extrapolated analytics. #### Confidence Layer Each monitored area includes a clear, colour-coded reliability layer: - Green: ideal conditions for accurate analysis - Grey: possible atmospheric interference - Red: presence of built structures that may skew results - Over 90% reduction in processing times by focusing only on new incoming data - Fully automated data acquisition and updates - Automated quality control processes Users can view a percentage breakdown of these conditions, giving them clarity on when and where the data can be trusted. #### Traceability Analytics A simple binary “Yes/No” timeline indicates when atmospheric conditions allowed for valid data collection. This transparency builds trust in satellite-derived insights and allows operators to plan actions with confidence. #### Operational efficiency at scale The system represents a shift from fragmented, reactive monitoring toward continuous, scalable oversight. Key improvements included: enable of near-real-time access to key indicators that support proactive water governance. ## The impact By leveraging trusted European satellite infrastructure, Earthpulse delivered a scalable and sustainable solution that supports informed decision-making today — and long-term resilience tomorrow. By integrating satellite intelligence into its workflow, Aigües de Manresa achieved: 1. Faster processing and significantly reduced response times. 2. Advanced filtering and automated quality control increased reliability, while confidence layers made the system accessible to both technical and non-technical users. 3. New spatial and temporal indicators allow authorities to take targeted action during critical events and manage water resources more proactively.   Acknowledgements: Aigües deManresa, Copernicus Content from: [NEREUS (Network of European Regions Using Space Technologies)](https://www.nereus-regions.eu/wp-content/uploads/dlm_uploads/2025/12/C4R_144-Advancing-Water-Monitoring-with-Satellite-Data.pdf) ## Share: - [Share on Facebook](https://www.facebook.com/sharer.php?u=https://www.earthpulse.ai/resources/advancing-water-monitoring) - [Share on X](https://twitter.com/intent/tweet?url=https://www.earthpulse.ai/resources/advancing-water-monitoring) - [Share on LinkedIn](https://www.linkedin.com/sharing/share-offsite/?url=https://www.earthpulse.ai/resources/advancing-water-monitoring) ## Related Articles [View All](https://www.earthpulse.ai/resources) ## [![A new evidence-based system to strengthen drought resilience in the Horn of Africa](https://www.earthpulse.ai/hubfs/The_Horn_of_Africa.jpg?noresize) News 27 May 2026 A new evidence-based system to strengthen drought resilience in the Horn of Africa Earthpulse Team](https://www.earthpulse.ai/resources/a-new-evidence-based-system-to-strengthen-drought-resilience-in-the-horn-of-africa) ## [![From space to preparedness](https://www.earthpulse.ai/hubfs/Screenshot%202026-02-20%20at%2016.44.39.png?noresize) Case study 26 Jan 2026 From space to preparedness ![false](https://www.earthpulse.ai/hubfs/favicon-1.ico?noresize) EarthPulse Team](https://www.earthpulse.ai/resources/from-space-to-preparedness) ## [![RISKCHAIN a simulator for smarter supply chains](https://www.earthpulse.ai/hubfs/22.png?noresize) Case study 02 Dec 2025 RISKCHAIN a simulator for smarter supply chains ![false](https://www.earthpulse.ai/hubfs/favicon-1.ico?noresize) EarthPulse Team](https://www.earthpulse.ai/resources/riskchain-a-simulator-for-smarter-supply-chains) [Home Earthpulse](https://www.earthpulse.ai/) - [Visit us on LinkedIn](https://www.linkedin.com/company/earthpulse-sl/) San Juan de la Salle 42, 315 Edificio Sant Gervasi SG.2.08 08022, Barcelona [info@earthpulse.ai](mailto:info@earthpulse.ai) [For media enquiries media@earthpulse.ai](mailto:media@earthpulse.ai) [+34 628 772 669](tel:+34628772669) - Solutions - [Strategic Intelligence](https://www.earthpulse.ai/solutions/strategic-intelligence) - [Operational Intelligence](https://www.earthpulse.ai/solutions/operation-intelligence) - [Compliance](https://www.earthpulse.ai/solutions/compliance-through-satellite) - [Pulses - Custom Solutions](https://www.earthpulse.ai/solutions/pulses) - [Solutions Catalogue](https://www.earthpulse.ai/solutions-catalogue) - [See all solutions](https://www.earthpulse.ai/solutions) - Products - [SPAI](https://www.earthpulse.ai/products/spai) - [Earthpulse!
