EU Horizon Europe: Climate-Resilient WASH Governance and Capacity Building for Local Authorities

The European Commission's Horizon Europe Cluster 6 call, 'Climate-Resilient WASH Governance and Capacity Building for Local Authorities' (HORIZON-CL6-2026-WASH-GOVERNANCE-01), is a timely and strategic intervention designed to address the compounding impacts of climate change on municipal water systems. Across the European continent and its associated regions, the traditional assumptions of hydrological stationarity are no longer valid. Local authorities, who bear the primary responsibility for delivering safe, reliable, and equitable water, sanitation, and hygiene (WASH) services, are facing unprecedented challenges. These include intense precipitation events that overwhelm combined sewer systems, prolonged droughts that deplete groundwater reserves and increase pollutant concentrations, and rising temperatures that facilitate the proliferation of waterborne pathogens. This call recognizes that technical engineering solutions alone are insufficient; they must be supported by robust, adaptive, and inclusive governance frameworks. To address these systemic challenges, the call funds projects that focus on capacity building, institutional reform, and the co-design of localized governance models. The European Commission aims to bridge the gap between high-level climate science and the daily operational realities of municipal water management. Consortia applying for this grant must propose innovative methodologies to enhance the climate literacy of local decision-makers, integrate nature-based solutions (NbS) into urban planning, and establish participatory decision-making processes that engage all segments of society. By doing so, the call seeks to foster a culture of proactive risk management, ensuring that local water infrastructure is not only resilient to current climate shocks but is also adaptable to future, highly uncertain climate scenarios.

The European Commission's Horizon Europe Cluster 6 call, 'Climate-Resilient WASH Governance and Capacity Building for Local Authorities' (HORIZON-CL6-2026-WASH-GOVERNANCE-01), is a timely and strategic intervention designed to address the compounding impacts of climate change on municipal water systems.

Who is it For?

This funding opportunity is specifically designed for transdisciplinary consortia capable of bridging the gap between high-level scientific research and localized municipal execution. Eligible applicants must form a consortium comprising a minimum of three independent legal entities established in different EU Member States or Horizon Europe Associated Countries, with at least one entity established in an EU Member State. The ideal recipient profile includes local and regional public authorities (such as municipal councils, provincial governments, and regional development agencies) who hold direct mandate over water and sanitation services. Additionally, municipal water utilities, river basin management authorities, and civil society organizations (CSOs) focusing on environmental justice and public health are critical partners. Academic and research institutions specializing in hydrology, climate modeling, public policy, and social sciences are required to provide the empirical foundation for the projects. Capacity-building organizations, non-governmental organizations (NGOs), and professional training institutes like GSLI are highly valued partners, as they possess the pedagogical expertise to design, deliver, and sustain the institutional training programs mandated by the call. Private sector entities, particularly small and medium-sized enterprises (SMEs) specializing in water technology, digital twin modeling, and smart monitoring systems, are also encouraged to participate to drive technological innovation within the consortia.

Priorities

The European Commission's investment priorities for this call are anchored in the systemic transformation of local water governance to withstand cascading climate shocks. The primary Key Performance Indicators (KPIs) focus on the measurable enhancement of institutional capacity within local authorities. Projects must demonstrate how they will increase the climate literacy of municipal decision-makers, enabling them to integrate long-term climate projections into daily infrastructure planning and capital investment cycles. Another core priority is the promotion of Integrated Water Resources Management (IWRM) principles, ensuring that water supply, sanitation, and stormwater management are not treated as isolated silos but as interconnected components of a single hydrological system. The donor prioritizes the deployment of nature-based solutions (NbS)—such as constructed wetlands, bioswales, and permeable pavements—alongside traditional grey infrastructure to enhance climate resilience and biodiversity. Furthermore, the call places a heavy emphasis on social equity, demanding that projects actively address the needs of vulnerable, marginalized, or water-stressed populations, thereby operationalizing the human right to water and sanitation. Consortia must also establish robust, replicable governance models that can be upscaled to the EU level, influencing future policy iterations and financial instruments.

Eligibility

Navigating the eligibility criteria for Horizon Europe requires a meticulous, multi-layered compliance audit spanning financial, spatial, and corporate legal dimensions. Legally, all consortium partners must possess a valid Participant Identification Code (PIC) and have their legal entity status validated by the European Commission's Validation Services. The coordinating institution must demonstrate exceptional operational capacity, backed by a proven track record of managing multi-million euro, multi-partner European grants. Financially, partners must undergo a rigorous financial viability check, proving they possess the liquidity, debt-to-equity ratios, and cash flow stability required to manage pre-financing and co-financing structures without risking project interruption. Spatially, the project activities must be executed within EU Member States or eligible Associated Countries, though international cooperation with low- and middle-income countries is highly encouraged where it adds clear strategic value to the EU's global commitments. Compliance with the 'Do No Significant Harm' (DNSH) principle is a mandatory threshold; no project activity may cause significant detriment to any of the six environmental objectives defined under the EU Taxonomy Regulation. Additionally, all public bodies and research organizations from Member States and Associated Countries must have a formal, public-facing Gender Equality Plan (GEP) in place to be deemed eligible for funding.

Path to Success

Achieving success in securing and executing this prestigious Horizon Europe grant requires a highly strategic, phased roadmap that integrates GSLI's elite training methodologies. Step 1: Consortium Architecture and Co-Design. Consortia must be built around a shared vision, balancing scientific excellence with practical municipal execution. Utilizing GSLI's 'Writing Winning Proposals' framework, partners will co-design a methodology that directly addresses the call's expected impacts, ensuring clear work packages, realistic deliverables, and a balanced budget distribution. Step 2: Baseline Vulnerability and Governance Audits. Before implementing interventions, the consortium must conduct rigorous baseline assessments of local water infrastructure and governance structures. By integrating GSLI's 'Monitoring & Evaluation (M&E)' methodologies, partners can establish scientifically validated indicators to measure capacity growth and resilience metrics over the project's lifecycle. Step 3: Institutional Capacity Building and Training Deployment. The core of the project lies in empowering local authorities. Consortia should embed GSLI's specialized courses—specifically 'WASH (Water, Sanitation, and Hygiene)' and 'Project Management for Development'—directly into their work packages. This ensures that municipal staff receive world-class, certified training in climate-resilient water safety planning, asset management, and participatory governance. Step 4: Policy Upscaling and Financial Sustainability. To ensure long-term impact, the project must translate local successes into national and European policy recommendations. By leveraging GSLI's 'Grants Management' and 'Fundraising & Resource Mobilization' strategies, the consortium can design robust exploitation plans, securing follow-on public and private investment to scale up the piloted climate-resilient WASH models beyond the grant's duration.
