200 tonnes of wet wipes removed from the sewer network in southern Tenerife

Entemanser has removed around 200 tonnes of wet wipes and other waste from the 34 wastewater pumping stations it operates in Adeje, Guía de Isora and Granadilla de Abona during 2026. The work has required more than 6,500 hours. A build-up of this waste can reduce pump efficiency, cause blockages and, in serious cases, contribute to sewage overflows or discharges.

Los Letrados wastewater treatment plant starts receiving wastewater

The Los Letrados wastewater treatment plant began receiving its first flows, initially from San Isidro, as the new Granadilla sanitation and treatment system moved into operation.

Operational milestone of the same project whose construction stage is recorded in the 2023 Granadilla sanitation system entry. This infrastructure action does not in itself imply any change in current bathing-water quality.

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.

Major Granadilla wastewater treatment and collection system under construction

By 2023, construction was progressing across the major Granadilla wastewater treatment and sanitation programme. The programme includes the Los Letrados treatment plant, treatment and pumping infrastructure at Ensenada Pelada, main sewer collectors serving inland areas, and coastal pumping stations and pressure pipelines. This is the earlier construction stage of the system that later began entering operation in 2026.

Earlier stage of the same project as the Los Letrados treatment plant starting to receive wastewater (5 February 2026). This is a regional wastewater infrastructure programme and does not by itself indicate bathing-water conditions at individual beaches.
