Regulation (EU) 2020/741 of the European Parliament and of the Council on minimum requirements for water reuse.

This Regulation lays down minimum requirements for water quality and monitoring and provisions on risk management, for the safe use of reclaimed water in the context of integrated water management. The purpose of these provisions is to guarantee that reclaimed water is safe for agricultural irrigation, thereby ensuring a high level of protection of the environment and of human and animal health, promoting the circular economy, supporting adaptation to climate change, and contributing to the objectives of Directive 2000/60/EC by addressing water scarcity and the resulting pressure on water resources, in a coordinated way throughout the European Union.
The Regulation applies whenever treated urban waste water is reused, in accordance with article 12(1) of Directive 91/271/EEC, for agricultural irrigation. For the purpose of producing, supplying and using reclaimed water, the competent authority shall ensure that a water reuse risk management plan is established. Member States in which reclaimed water is used for agricultural irrigation shall ensure that adequate and up-to-date information on water reuse is available to the public, online or by other means.
A Member State may decide that it is not appropriate to reuse water for agricultural irrigation in one or more of its river basin districts or parts thereof, taking into account the following criteria: (a) the geographic and climatic conditions of the district or parts thereof; (b) the pressures on and the status of other water resources, including the quantitative status of groundwater bodies as referred to in Directive 2000/60/EC; (c) the pressures on and the status of the surface water bodies in which treated urban waste water is discharged; (d) the environmental and resource costs of reclaimed water and of other water resources.
