water reuse

In the research project FITWAS (reuse of filter backwash water from the treatment of groundwater for the protection of the drinking water supply), five partners from the fields of research, water supply and industry join the German Environment Agency to analyse methods for reusing filter backwash water produced during drinking water treatment to conserve drinking water reserves.

Water Reuse, the use of reclaimed water from treated wastewater, has been a long-established reality in many (semi)arid countries and regions. It helps to alleviate water scarcity by supplementing limited freshwater resources.

Water reuse can help alleviate water shortages. But reclaimed water can contain pathogens and pollutants. Questions and answers on the proposal for a regulation submitted by the European Commission on 28 May 2018.

The reuse of treated waste water can help to reduce water shortages. Reused water can contain pathogens and harmful substances, however. On 28 May 2018, the EU Commission proposed a regulation, on minimum requirements concerning the reuse of water. It aims to protect health and the environment. The UBA considers there to be a need for improvement.

The use of treated wastewater, e.g. for agricultural irrigation, can alleviate pressures on water resources. At the same time it poses risks as treated wastewater can contain pathogens and chemicals. By May 2018 the European Commission wants to publish a regulatory proposal for requirements. UBA President Krautzberger and EU Parliamentarian Wölken invited for a discussion on 22 March in Brussels.

The EU Commission is seeking to adopt EU wide minimum quality requirements for water reuse for agricultural irrigation and groundwater recharge by the end of 2017. As the current draft falls short to set standards that are rigorous enough to protect the environment and human health, UBA has published a Scientific Opinion Paper to express its concerns and recommendations.
