The WaterClue project proposes a transformative approach to enhance drinking water treatment systems by leveraging real-time data analysis, predictive modeling, and intelligent optimization. Climate-resilient water supply systems are key for ensuring the delivery of safe and high-quality drinking water, given the growing challenges posed by alterations in surface water sources and the implications of global warming on water quantity and quality. This research aims to identify dissolved organic matter (DOM) proxies related with the reactivity with disinfectants and its relationship with the formation of disinfection by-products (DBPs) during water treatment.

The project focuses on three key objectives: to integrate fast online multiparametric sensors for continuous monitoring of DOM variations; to develop predictive models correlating DOM proxies with DBP formation; and to optimize DWTP operations by applying real-time data and predictive models to adjust dosages and operating conditions effectively to mitigate chemical and microbial risks.

WaterClue’s novelty lies in the specific context it addresses: an Early Warning System (EWS) for DWTPs and distribution networks. By combining online sensor technology, advanced analytics, and predictive modeling, the project enables proactive monitoring and timely detection of potential DBP-related risks. This approach facilitates prompt corrective actions and interventions, ultimately enhancing the resilience and responsiveness of DWTPs.

The project builds upon the solid foundation of the principal investigator, Dr. Monclús, who has demonstrated expertise through previous contributions, including developing the SmartAirMBR® system, decision support systems for water treatment, and DrinkIA® Digital Twin Technology. Dr. Monclús has actively collaborated with leading water companies, gaining insights from water practitioners and consolidating strategic local and regional partnerships.

WaterClue’s scientific and technical impacts are substantial. It will advance the understanding of DBP formation and factors influencing drinking water treatment. The project will foster the digitalization of the water sector, aligning with the EU and global initiatives. By optimizing water treatment processes, WaterClue will contribute to increased water security, improved public health, and enhanced resilience to climate change and water scarcity.

The expected social and economic outcomes are noteworthy. WaterClue will enhance water security, ensuring a more reliable and secure water supply. Improved public health will be achieved by reducing adverse health effects associated with DBPs. The project will aid in addressing climate change impacts on water resources and contribute to the competitiveness of the Spanish water sector.

WaterClue’s transformative research aligns with the UN Sustainable Development Goals, the Spanish Strategy for RDI 2021-2027, and the EU’s environmental, climate, and digitalization targets. Through interdisciplinary research and collaboration, WaterClue will deliver innovative solutions that positively impact drinking water treatment practices and contribute to a sustainable and resilient water future.
