Water Reuse Europe | Water Europe Joint Webinar on Agricultural water reuse in Europe: status, challenges and opportunities for further growth

27th June 2023 @ 2:00 pm - 4:00 pm CEST


According to the latest report from the JRC Global Drought Observatory on Drought in Europe released in March 2023*, the impact of dry conditions on water resources availability this winter are already emerging in wide areas of western and north-western Europe and several smaller areas in southern Europe. In certain countries such as France, Spain, and northern Italy, these dry conditions are raising concerns as they follow similar patterns to the one observed in 2022 that resulted in extreme drought and impact on water supply and agriculture. Although the JRC Global Drought Observatory reports that “vegetation and crops at the beginning of the 2023 growing season have not been significantly affected yet, the current situation may become critical in the coming months if temperature and precipitation anomalies persists in spring.”

One way of alleviating the impact of drought on our water supply and more specifically agriculture, is water reuse. With this webinar, Water Reuse Europe and Water Europe – through the expertise of its Working Group on Water and Sustainable Agrifood Systems – are bringing together experts in the agricultural water reuse sector from across Europe, to discuss the status of water reuse through examples of good practices, the challenges faced to comply with the EU Regulation (Regulation (EU) 2020/741) on minimum requirements for water reuse coming into force on the 23rd of June 2023, and opportunities to further encourage circular approaches in the agricultural sector.


Water professionals, developers, industry leaders, solution providers, technology suppliers, policy makers, researchers, end-users, and consultants involved in or with an interest for water reuse.

Water Reuse in EU: Regulation on Minimum Requirements and JRC Guidelines on Risk Management Plan.
The EU Regulation 2020/741 sets out harmonized minimum water quality and monitoring requirements and risk management provisions for health and environmental risks for safe reuse of urban wastewater. The implementation of a risk management plan, a mandatory tool for the production, supplying and use of reclaimed water is based on the elements of the Annex II of the Regulation. The Joint Research Centre (JRC) of the European Commission and DG ENV has worked in close collaboration with experts, representatives of EU Member States, and stakeholders to provide guidelines on risk management. This presentation will give an overview of technical aspects of elements of risk management plan, along with practical examples for their application.

Water reuse risk management plans and digitalization: case studies in Italy.

Water reuse risk management plans (WRRMPs) are the key to adapt monitoring and management strategies to the local conditions and value chains. A proper combination of digitalization and conventional approach may optimize the risk management, even considering the Water-Energy-Food-Carbon nexus. The presentation will report case studies related to EU-funded projects Digital Water City, WATERUN and FIT4REUSE, while presenting a first full scale WRRMP in an Italian system.

Master plan of water reuse schemes and challenges in the Eastern Attica Region, Greece.
The region of East Attica in Greece faces stress on its water supply, caused mainly by agricultural activities and tourism in the summer. Thus, a master plan for effluent reuse from Eastern Attica’s wastewater treatment plants was carried out to identify best practices for water reclamation from municipal wastewater and to define the areas where reclaimed water may be applied. In particular, two major wastewater reuse projects in the East Attica region (Rafina/Artemida and Marathon agglomerations) were approved for co-financing by the European Union (EU) Cohesion funds and implementation by the Athens Water Supply and Sewerage Company (EYDAP S.A.). Whilst being compliant with the 91/271/E.E.C - Urban Wastewater Treatment Directive (UWWTD), the schemes need to produce treated wastewater effluents that comply with the Greek standards for unlimited irrigation and urban reuse (Joint Ministerial Decision 145116/2011). Furthermore, another wastewater project, co-financed with EU funds (beneficiary: Attica Prefecture) involving the non-compliant agglomerations of Koropi and Paiania, is being upgraded with advanced tertiary treatment that will also produce reclaimed water suitable for aquifer recharge to restore the water quality of groundwater bodies. In parallel, a comprehensive feasibility study shall be carried out to address key issues for successful water reuse implementation according to national and EU regulations (EU 2020/741) in the East Attica region.

Smart experimental platform to evaluate the effects of crops irrigation with treated wastewater.
Treated wastewater is an important resource that can mitigate negative effects of water scarcity and reduce use of artificial fertilisers, therefore increasing overall circularity and sustainability of the agricultural production. However, it is important to assess effects that this practice can have. A smart experimental platform in Italy, in Emilia-Romagna region, offers a closer view on these aspects. The ferti/irrigation is controlled by a central unit able to measure and integrate the load of nutrients administered to the plants (i.e. tomato and peach). Moreover, the UNIBO researchers are assessing the effect of treated wastewater on soil and crop quality.

Water reuse in agriculture: Exploiting synergies with the German national micropollutant strategy
To support the implementation of the EU water reuse regulation, the German Ministry of Research and Education launched a funding scheme of 30 M. In total, 13 projects are financed, of which four target water reuse in agriculture. One of these projects (FlexTreat) aims to combine the efforts in Germany and the revision process of the UWWTD to reduce micropollutants emissions with water reuse. The project investigates four different treatment schemes targeting both micropollutants removal and disinfection. One of these schemes is a combination of ozonation, dual media filtration, and UV disinfection at pilot scale. The focus is on treatment to achieve classes A and B for water reuse (E. coli target values: < 10 MPN/100 ml and < 100 MPN/100 ml, respectively). The analytical program includes chemical and physical parameters, microbiological parameters, and various micropollutants.
Results: In addition to the removal of trace substances, an improvement in UV transmissivity is achieved through ozonation which facilitates the operation of a downstream UV system. The data so far shows that the microbial requirements for Class A can only be achieved with a correspondingly higher ozone dose of 0.7 mg ozone/mg DOC, whereas with a lower ozone dose only the requirements for Class B could be achieved. The additional UV system is indispensable in both cases.
