From March 2nd to 4th, the serene landscape of Texel, Netherlands, became the hub for European water innovation. Acacia Water was honored to host the 3rd General Assembly of the MARCLAIMED EU consortium, bringing together partners from Portugal, Spain, Poland, Belgium, Austria, and France for three days of reflection, site exploration, and strategic planning. More Than Just a MeetingAt the heart of the MARCLAIMED project is the belief that while data and research are the foundation of our [...]

On 16 April 2026, Water Europe will host the 2026 edition of Water Market Europe (WME) at the NH Hotel Berlaymont in Brussels. This year’s event centers on the transformative potential of Digital Twins, Data Governance, and Artificial Intelligence within the water sector. The Strategy for Water ResilienceThe European Water Resilience Strategy provides a vital framework for increasing the continent’s adaptability and long-term sustainability in managing precious water resources. A primary pillar of this strategy is the large-scale [...]

On February 27, 2026, the MARCLAIMED project took center stage at the AdP Engineering Days, with AgdA - Águas Públicas do Alentejo, S.A. presenting the latest results from the Comporta Wastewater Treatment Plant (WWTP) demo site. The presentation highlighted the critical role of Managed Aquifer Recharge (MAR) using alternative water sources—a core focus of our EU-funded initiative. By utilizing treated wastewater to replenish underground aquifers, the project is demonstrating innovative, sustainable solutions for the future of water resource [...]

MS4 approach (Final Monitoring Phase) and ERSAR Innovation Awards The MARCLAIMED project is starting 2026 with significant recognition and technical advancements at the Comporta Wastewater Treatment Plant (WWTP) demo site. MS4 approach (Final Monitoring Phase): LNEC and AgdA teams successfully completed the 7th sampling campaign (January 2026). This indicates the last stage in a comprehensive two-year water sampling strategy, with the 8th and final campaign scheduled for April 2026. This will fed D4.1. The chemical analysis performed from [...]

In a Managed Aquifer Recharge system (MAR) with Alternative Water Resources (AWR), it is crucial to transform the risk factors into quantifiable indicators. By doing so, it is possible to systematically monitor and assess risks in real time, enabling timely interventions and adjustments to mitigate them effectively. Within this framework, MARCLAIMED partners from Aigües de Barcelona, Agència Catalana de l'Aigua and CETAQUA designed Maraiser to help manage MAR systems by establishing a full set of health, environmental, and [...]

The MARCLAIMED project successfully held its third 3rd Community of Practice (CoP) workshop for Demo Case 2 in Comporta, Portugal, on December 5th, 2025, taking a significant step toward addressing the gap between technical innovation and social acceptance of Managed Aquifer Recharge (MAR). Organized in the Laboratório Nacional de Engenharia Civil (LNEC), the session reunited with the Community of Practices (CoP) to expand upon the "Personas exercise" initiated in the 2nd workshop. The session focused on identifying and [...]

The MARCLAIMED project successfully held its third stakeholder workshop to continue strengthening trust in reclaimed water as a key solution for water resilience in the Llobregat river basin. Organised in collaboration with Aigües de Barcelona, the session brought together members of the Community of Practice to discuss ongoing challenges and opportunities related to the use of high-quality reclaimed water to support the region’s aquifers. As part of the workshop, participants visited the project’s recharge ponds, which play a [...]

The MARCLAIMED project was prominently featured during a technical workshop held yesterday at the University of Málaga, organised by Cetaqua – Water Technology Centre together with the CEHIUMA Research Centre. The event brought together leading experts from Andalusian public administrations and water operators, including ACOSOL, Aigües de Barcelona and EMASA, to explore the opportunities and challenges of using reclaimed water for Managed Aquifer Recharge (MAR). During the session, Sara Espinosa Martínez and Damián Sánchez García shared insights and [...]

The MARCLAIMED project was broadly promoted during Water Projects Europe (WPE), held on 3 December as part of the Water Knowledge Europe brokerage event, organised by Water Europe at the Thon Hotel EU. The session, titled “From Alternative Water to Circular Solutions”, brought together leading EU-funded initiatives working on water resilience, circularity, and climate adaptation. Together, the five projects, AWARD, RECREATE, CIRSEAU and BOOST-IN illustrated how pioneering demonstrations and systemic strategies can connect to drive the transition towards [...]

MARCLAIMED is participating in the upcoming Water Projects Europe – From Alternative Water to Circular Solutions, taking place on 3 December 2025 (9:00–12:30) at Thon Hotel EU, Brussels. Held within the framework of Water Knowledge Europe, this edition will unite leading EU-funded water innovation projects to explore how Europe can strengthen resilience and accelerate its transition toward a circular and climate-adapted water future. As climate change intensifies pressures on Europe’s water systems, the need for new and reliable [...]

As Europe faces mounting challenges from water scarcity and drought, the EU-funded MARCLAIMED project has launched its official video, introducing how it is pioneering new ways to secure sustainable water resources across the continent. The video highlights MARCLAIMED’s integrated approach, which combines two resilient solutions — Managed Aquifer Recharge (MAR) and Alternative Water Resources (AWR) — to address water stress and enhance Europe’s ability to cope with droughts. By improving how runoff and reclaimed water are stored, managed, [...]

The MARCLAIMED project creates an integrated decision‑support environment built around a high‑fidelity digital twin of river‑basin and aquifer systems. Real‑time sensor feeds, including hydrological, meteorological, water‑quality and infrastructure data, are exchanged using the NGSI‑LD standard and are coupled with physics‑based hydraulic models, producing a continuously updated virtual replica of the water network across the three demonstration sites in Portugal, Spain and the Netherlands. This virtual replica serves as the foundation for three AI‑driven tools that work on a [...]
