Dry soil due to drought

In August 2022, the EU Joint Research Centre (JRC) warned that the current drought could be the worst in 500 years and predicted that severe drought will worsen in Europe, potentially reaching 47% of the continent.

According to the European Drought Observatory, the dry conditions are related to a broad and persistent lack of precipitation combined with a sequence of heat waves. The severe precipitation deficit has affected river discharges widely across Europe with major impacts on the energy, food and transport sectors.

Already in its 2018 report ‘Impact of a changing climate, land use, and water usage on Europe’s water resources’, the JRC projected significant increases in water scarcity as a result of reduced overall rainfall thus reduced water availability, an increase in extreme drought events and increased water needs. 

At the time, the JRC estimated an annual loss of 810 million cubic meters of water, translating into reduced availability of water for irrigation of agricultural crops and hence reduced availability of food. 

Reusing water

Reusing reclaimed water is widely recognised as a practice that helps manage water resources more efficiently. The Water Reuse Regulation sets out minimum water quality, risk management and monitoring requirements to ensure safe water reuse. The Regulation will apply from 26 June 2023 and is expected to encourage and facilitate water reuse in the EU.

The European Commission has prepared, in consultation with the Member States and stakeholders, guidelines to help apply the Water Reuse Regulation. The Commission Notice was adopted on 3 August 2022 to help the Member States and stakeholders apply the rules on the safe reuse of treated urban wastewater for agricultural irrigation.

It provides guidance on the general and administrative obligations set out by the Regulation, its scope of application, and its technical aspects, such as risk management and validation monitoring.

Commissioner for the Environment, Fisheries and Oceans Virginijus Sinkevičius, underlines: “Freshwater resources are scarce and increasingly under pressure. In times of unprecedented temperature peaks, we need to stop wasting water and use this resource more efficiently to adapt to the changing climate and ensure the security and sustainability of our agricultural supply.”

Inspiring water reuse examples

The Interreg Europe community has also identified a wealth of good practices with regard to water reuse. In particular, the AQUARES project has published the Water Reuse Technology Application Guide and put forward a number of excellent water reuse examples.

As a result of the lessons learnt from the other partners in the project, the Lombardy Foundation for the Environment (Italy) has contributed to a modification of the Regional Operational Programme (ROP) in Lombardy by introducing water reuse measures in the grants “Tourism and attractivity” financed by the ROP.

In the edition 2021, 42% of projects approved and financed included also water saving, as part of more general investments related to touristic infrastructures (hotel, camping), and 12% included water reuse measures. More information is available in the  Action Plan for Lombardy Region in the integration of water reuse in tourism and leisure facilities (Italy)

Regions and municipalities that face policy challenges related to water reuse, can also apply for a tailor-made Peer Review to get input from their homologues.
