The collaborative effort developed by 16 projects
The ZeroPollution4Water Cluster was founded by seven Horizon projects and has now expanded to nine additional initiatives, broadening its vision across the entire water cycle and reinforcing its commitment to Europe’s zero-pollution ambitions.
Each project contributes case studies from different regions, addressing key challenges in drinking water and groundwater management. By connecting these cases, the Cluster fosters shared knowledge across Europe, Africa, and the Americas — and remains open to collaboration with new projects working toward safer, pollution-free water systems.
Founding projects
Innovative tools to control organic matter and disinfection byproducts in drinking water.
The intoDBP project, funded by the EU, focuses on disinfection by-products (DBPs) formed during water chlorination. It develops innovative tools for water quality management, emphasizing cost-effective sensors and analytical methods. intoDBP aims to understand DBP precursors, address pollution and risks, and promote sustainable consumer behavior. The project engages society through surveys, contributes to climate change adaptation, and enhances water treatme
Understanding groundwater Pollution to protect and enhance WATERquality.
The UPWATER project addresses the widespread issue of groundwater pollution by identifying effective regulatory and legislative preventive measures and by developing cost-efficient methods to measure pollutants, identify their sources and to mitigate the pollution. UPWATER focuses on the validation of these methods in three case studies in different EU climates and aims to develop hydrogeological models for decision-making scenarios, considering multiple stressors and climate change projections. Expected outcomes include the adoption of preventive measures, scaled-up bio-based solutions and updated chemical priority lists.
TOolkit for aDaptable, Resilient INstallations securing high Quality drinking water
The ToDrinQ project addresses the impact of climate change and increased pollution on drinking water quality. The project aims to develop real-time water quality monitoring technologies and innovative treatment systems, along with interoperable decision tools. These efforts support evidence-based treatment plant design and enhance operational awareness and response in the overall water system.
Innovative Integrated Tools and Technologies to Protect and Treat Drinking Water from Disinfection Byproducts (DBPs)
The H2OforAll project focuses on disinfection by-products (DBPs) that result from the interaction of disinfectants like chlorine with natural organic materials in water. It aims to develop cost-effective DBP sensor monitoring devices, model contaminant spread, study toxicity and environmental impact, and propose safeguarding measures for the drinking water chain. The project also works on innovative water treatment methods to remove or prevent DBPs, and it aims to create a central knowledge base with reliable data on DBPs in Europe and their effects.
Preventing groundwater contamination related to global and climate change through a holistic approach on managed aquifer recharge
MAR2PROTECT project confronts groundwater contamination resulting from climate change and global changes, with a focus on sustainable water management to meet zero pollution goals by 2030. It employs an innovative managed aquifer recharge (MAR) approach, utilizing the M-AI-R Decision Support System (DSS) that incorporates artificial intelligence (AI) to assess and enhance groundwater quality and quantity..
Climate-resilient management for safe disinfected and non-disinfected water supply systems
SafeCREW project addresses the challenge of supplying safe drinking water in the face of climate change. It aims to develop new methods for monitoring, treatment, and risk assessment, particularly in disinfection and organic substance removal, safeguarding water quality
Taking action to prevent and mitigate pollution of groundwater bodies
NINFA project confronts groundwater pollution by developing an early-warning decision support system and knowledge database, the NINFA Platform. This innovation enhances groundwater management by expanding knowledge on water flows and the behavior of emerging contaminants like pharmaceuticals and microplastics, safeguarding this vital resource.

New projects
Monitoring and tackling drinking water pollution, promoting global health and sustainability
NIAGARA is a ground-breaking initiative that addresses the monitoring of chemical and biological pollution in drinking water at the drinking water treatment plants level, new technologies for their removal, their associated potential toxicological effects, and the prediction of their spread and human exposition. It also develops a detailed characterization of these solutions and while assessing risks and sustainability associated with its future scaling. Finally, recommendations at the policy level will also be targeted.
Circular economy applied to nitrate removal hydrogen generation and waste recovery in drinking water
Nitrate pollution in surface and groundwater represents a prevalent and challenging issue for numerous European Union (EU) member states. The primary objective of this project is to develop an industrial-scale electrochemical denitrification technology for the removal of nitrate from underground waters and concentrated effluent streams (brines). This process will facilitate the recovery of industrial interest ionic compounds and a hydrogen stream suitable for energy applications. The technology will be implemented within a mobile pilot plant, validated in three distinct locations with high nitrate concentrations (two in Spain and Malta).
Closed-loop water systems in textile industrial districts: multimodal
orchestrated removal of emerging pollutants from textile wastewater
The LIFE-CASCADE project aims at developing analytical procedures and wastewater treatment technologies meant to detect and remove the two most critical categories of emerging micropollutants for the textile sector: poly- and per- fluorinated compounds (PFAS) and Microplastics. PFAS are among the most persistent critical micropollutants due to their impact on the
environment and on human health.
Preventing pollution from urban water runoff through data-driven hybrid nature based solutions
D4RUNOFF project will create a new framework for prevention and management through the data-driven design of hybrid nature-based solutions for current and future risk scenarios. Its approach will benefit urban planners, water utilities and policy makers. By defining urban runoff and stormwater management plans, the project will help optimise the quality of water that flows into bodies of water.

Knowledge and innovative solutions in agriculture for water availability and quality
UNIVERSWATER project brings together a consortium of 15 partners across six European countries. By integrating innovative portable sensors, earth observation imaging, and advanced AI, the project will improve water resource use and enhance on-farm treatment of dairy soiled water, mitigate soil salinisation, and optimise fertiliser/pesticide application. This initiative aims to revolutionise agri-water management, paving the way for smarter, more efficient water resource use and environmental stewardship.
Monitoring and modelling solutions for data-driven holistic management of urban water quality
Cities are a major source of pollution for urbanb waters. Unfortunately, local managers frequently lack the information needed to fight pollution from urban water systems. URBAN M2O project will create AI-enhanced monitoring tools and digital twins of cities’ water systems. Merging the data from these tools, cities will be able to pinpoint pollution hotspots and develop effective responses.
Integrated approach to urban water quality monitoring,
management and valorisation
UrbaQuantum advances a new, integrated approach to urban water management. The project develops innovative sensors, predictive models and a unified Urban Water Platform to improve decision-making across the entire water cycle. Through real-world use cases, UrbaQuantum enables early detection of pathogens, microplastics and emerging pollutants, better forecasting of sewer overflows, and a clearer understanding of urban pollution pathways.
A European initiative aimed at reducing Nitrogen and Phosphorus emissions while optimising nutrient flows.
NPower will model regional nutrient flows, demonstrate technologies and best practices, test recovered fertilisers, and develop governance measures tailored to territorial needs. Knowledge transfer among clusters ensures EU-wide relevance and replicability.
