Call content
short description
With the effect of climate change as well as the emergence of new threats from chemical, biological, human and cyber origins, it is necessary to develop and test a set of tools to ensure that water and sanitation provision is resilient now and for the future, building on the solutions that emerged in the sector or adapted from other sectors.
Call objectives
Water infrastructures both for drinking water supply and wastewater collection and treatment suffer from a lack of sufficient and continuous investment across Europe. Their conditions are evolving differently depending on the investment capacity of local authorities and/or water companies, as well as the climate and pollution conditions they are exposed to. They are often not flexible enough to adapt to a changing and increasingly unpredictable environment and lack of appropriate monitoring to properly understand their functioning in various operating conditions. On the treatment side, the technological processes are not always coping with pollution load variation or new contaminants threatening human health and downstream ecosystems. They are also more and more exposed to the risk of malicious attacks, being of human or cyber nature.
To achieve the expected outcomes, proposals should address some or all the elements below:
- develop and integrate modular processes and tools to improve the adaptability of drinking water and wastewater infrastructures to emerging pollutions and effects of climate change;
- integrate Nature-based Solutions infrastructures to reduce the carbon footprint of water infrastructure, better manage water flows and pollutants entering sewers, and support biodiversity;
- enhance the use of digital solutions, new monitoring techniques, Earth observation tools, digital twin technology and artificial intelligence, including for predictive analytics, within drinking water and wastewater infrastructures to optimise their operation, anticipate infrastructure challenges and pollution and improve their efficiency and resilience, addressing leakages, infiltration, energy consumption, recovery of materials and carbon footprint;
- develop robust data sharing framework to promote secure collaboration among stakeholders and identify interdependencies with other critical infrastructures in a resilience-based approach;
- develop tools, approaches and procedures to protect both the physical and digital water infrastructures against malicious attacks.
Proposals are encouraged to explore the use of blockchain or other distributed ledger technologies to ensure data integrity, enable smart-contract–based service automation, and support novel financing or certification schemes for future water infrastructures. Given the high degree of integration of the topic with existing infrastructures, proposals should target a large variety of stakeholders ranging from universities, SMEs, water utilities, energy utilities, etc.
Proposals should also seek to contribute to the further development of existing observing platforms and initiatives, including to the evolution of Copernicus services and the future EU Digital Twin on freshwater and Destination Earth. It should also contribute to define the bases for a FAIR (Findable, Accessible, Interoperable and Re-usable) sharing of data in the water sector in collaboration with the initiative conducted by the co-funded partnership Water Security for the Planet (Water4All).
All in-situ data collected through actions funded from this call should follow INSPIRE principles and be available through open access repositories (e.g. Copernicus). supported by the European Commission.
Proposals should also build on the results of previous projects funded under previous framework programmes, especially the projects related to the cluster ICT4Water. They should also foster complementarities and avoid overlapping with projects funded under the Mission Restore our Ocean and Waters by 2030 and the EU Mission on Adaptation to Climate Change. Finally, it should also look for collaboration with projects from Horizon Europe Cluster 3 in relation to security, where appropriate. The JRC may contribute with technical analysis and research on digital technologies for water management and monitoring, including real-world test cases.
International cooperation is strongly encouraged.

Expected results
Project results are expected to contribute to all of the following expected outcomes:
- water infrastructures are flexible enough to face changes in hydraulic flow and pollution load from emerging or yet unknown contaminants to ensure that access to water and sanitation is protected on a long-term, recovery of safe secondary resources is secured and greenhouse gas emissions are reduced and ecosystems are protected;
- water infrastructures have integrated digital solutions (e.g., smart sensors, IoT, digital twins and artificial intelligence) as well as citizen science to optimally operate in changing conditions from climate or pollution pressures, facilitate appropriate water pricing based on reliable monitoring of water consumption, favour recovery of material and limit greenhouse gas emissions;
- water infrastructures have incorporated the necessary tools and protection to avoid cyber and/or terrorist attacks to ensure their resilience against malicious behaviour;
- new or renewed water infrastructures are designed following ‘good practices’ to maximise system resilience, build redundancy, and ensure ecological and social sustainability;
- water infrastructures are better designed thanks to improved predictions, robust assessment of impacts and implementation of appropriate mitigation measures due to advances on the understanding of how, when and where floods and droughts occur.

Legal entities which are established in countries not listed above will be eligible for funding if provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
Any legal entity, regardless of its place of establishment, including legal entities from non associated third countries or international organisations (including international European research organisations) is eligible to participate (whether it is eligible for funding or not), provided that the conditions laid down in the Horizon Europe Regulation have been met, along with any other conditions laid down in the specific call/topic.
A ‘legal entity’ means any natural or legal person created and recognised as such under national law, EU law or international law, which has legal personality and which may, acting in its own name, exercise rights and be subject to obligations, or an entity without legal personality.
Unless otherwise provided for in the specific call/topic conditions, only legal entities forming a consortium are eligible to participate in actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:
- at least one independent legal entity established in a Member State; and
- at least two other independent legal entities, each established in different Member States or Associated Countries.
As affiliated entities do not sign the grant agreement, they do not count towards the minimum eligibility criteria for consortium composition (if any).
The Joint Research Centre (JRC) may participate as member of the consortium selected for funding as a beneficiary with zero funding, or as an associated partner. The JRC will not participate in the preparation and submission of the proposal - see General Annex B.
If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).
other eligibility criteria
Specific cases
Affiliated entities — Affiliated entities (i.e. entities with a legal or capital link to a beneficiary which participate in the action with similar rights and obligations to the beneficiaries, but which do not sign the grant agreement and therefore do not become beneficiaries themselves) are allowed, if they are eligible for participation and funding.
Associated partners — Associated partners (i.e. entities which participate in the action without signing the grant agreement, and without the right to charge costs or claim contributions) are allowed, subject to any specific call/topic conditions.
Entities without legal personality — Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees to protect the EU’s financial interests equivalent to those offered by legal persons.
EU bodies — Legal entities created under EU law including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
Joint Research Centre (‘JRC’) — Where provided for in the specific call/topic conditions, applicants may include in their proposals the possible contribution of the JRC, but the JRC will not participate in the preparation and submission of the proposal. Applicants will indicate the contribution that the JRC could bring to the project based on the scope of the topic text. After the evaluation process, the JRC and the consortium selected for funding may come to an agreement on the specific terms of the participation of the JRC. If an agreement is found, the JRC may accede to the grant agreement as beneficiary requesting zero funding or participate as an associated partner, and would accede to the consortium as a member.
Associations and interest groupings — Entities composed of members (e.g. European research infrastructure consortia (ERICs)) may participate as ‘sole beneficiaries’ or ‘beneficiaries without legal personality’. However, if the action is in practice implemented by the individual members, those members should also participate either as beneficiaries or as affiliated entities (otherwise their costs will NOT be eligible).
EU restrictive measures — Entities subject to EU restrictive measures under Article 29 of the Treaty on the European Union (TEU) and Article 215 of the Treaty on the Functioning of the EU (TFEU) as well as Article 75 TFEU, are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any).
Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine — Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons.
With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014) concerning restrictive measures in view of Russia’s actions destabilising the situation in Ukraine, legal entities established outside Russia whose proprietary rights are directly or indirectly owned for more than 50% by a legal person, entity or body established in Russia are also not eligible to participate in any capacity.
Measures for the protection of the Union budget against breaches of the principles of the rule of law in Hungary — Following the Council Implementing Decision (EU) 2022/2506, as of 16 December 2022, no legal commitments can be entered into with Hungarian public interest trusts established under the Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals and can participate without receiving EU funding, as associated partners, if allowed by the call conditions. However, as long as the Council measures are not lifted, such entities are not eligible to participate in any funded role (beneficiaries, affiliated entities, subcontractors, recipients of financial support to third parties, etc.). In the case of multi-beneficiary grant calls, applicants will be invited to remove or replace that entity in any funded role and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly.
