CJEU finds further breaches of the EU Urban Waste Water Treatment Directive affecting Tenerife
The Court of Justice of the European Union ruled that Spain had failed to fulfil several obligations under Directive 91/271/EEC in a number of agglomerations covered by case C-433/23, several of them located in Tenerife. The judgment concerns obligations linked to the collection, treatment and monitoring of urban waste water.
A European judgment records past failures and requires them to be corrected. It does not by itself state the situation at any beach on the day it is consulted.

European Commission refers Spain to the CJEU over wastewater failures affecting Tenerife
The European Commission took Spain to the Court of Justice of the European Union over failures to comply with Directive 91/271/EEC on urban waste water treatment. The case covers several agglomerations in Tenerife, among them Adeje-Arona, Añaza, Candelaria, Golf del Sur, Guía de Isora Litoral, La Esperanza-La Laguna Sur-Santa Cruz-Valles, Puerto de Santiago-Playa la Arena, San Isidro-Litoral, Sueño Azul and Valle de la Orotava.
An infringement procedure is brought against Spain and describes unfulfilled obligations at agglomeration level, not the water quality at a beach on a given day. The required works and connections fall to different administrations.
