The European Commission said on Wednesday that it has referred Hungary to the EU's Luxembourg court over its failure to comply with the common directive on urban waste water treatment. Under the directive, EU member states must ensure that urban agglomerations properly collect and treat their waste waters with the aim to eliminate or mitigate their undesirable effects. In a statement, the EC noted the common European Green Deal legislation which sets a zero pollution goal for every member state. "Full implementation of the standards enshrined in EU legislation is important to effectively protect human health and safeguard the natural environment," the commission said.
