ACUAES details the tender and progress of the systems
ACUAES authorises a €2,095,269 tender with a five-month execution period for the final incoming pumping pipelines, part of the terrestrial outfall and the access road. The plant is in its final phase, awaiting completion of its electrical connection following Energy Directorate approval. Arona Este is 73% complete, San Miguel 63% and the Palm-Mar connection 25%, with completion expected in mid-2027. Plant trials are expected in summer 2027, followed by progressive receipt of wastewater. Seven- and four-kilometre terrestrial outfalls have been built to connect to the existing submarine outfalls in both municipalities for surplus not sent to the reuse reservoir. These are infrastructure works, not confirmation of contamination.

Los Cristianos loses its Blue Flag over water quality
Los Cristianos beach (Arona) did not receive the Blue Flag for the 2026 season. According to ADEAC, the reason was not achieving an "excellent" water-quality rating in the scientific sampling, one of the required criteria. Arona Town Council stated that the area remained suitable for bathing throughout the period analysed and that in 2025 there were three isolated samplings where the rating moved from "excellent" to "good", never reaching "insufficient". Losing a voluntary award is not a bathing closure and does not affect the historical profile.

Report on the southern coastline during storm Therese
A press report described the situation along the southern coast of Tenerife (Los Cristianos, Las Vistas, El Camisón and Playa de las Américas) during storm Therese, with debris and wipes in the water and accounts from lifeguards and beachgoers. The article expressly states that the beaches remained open under red flags and were not sealed off. It also notes that the Ministry of Health recorded at least 29 short-duration contamination incidents in the Canary Islands in 2024. No official bathing ban is documented for this episode, so the entry is recorded as context and affects no score.

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.
