Water quality in Granadilla de Abona

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.

ACUAES reported that approximately €158 million had already been executed within the major Tenerife sanitation and wastewater-treatment programme, representing about 67% of planned execution. The update included commissioning work at the Oeste and Los Letrados systems.

This infrastructure action does not in itself imply any change in current bathing-water quality.

El Día reports that the start-up of the Los Letrados plant (Granadilla de Abona) and the Oeste plant (Guía de Isora) raises Tenerife's treatment capacity to more than 35 cubic hectometres a year, over 50% of the island's wastewater flow, extending coverage by more than 80,000 inhabitants. Los Letrados involved an investment of 17.6 million euros and includes 10 kilometres of collectors serving Granadilla town, El Salto and San Isidro, plus an 8.5-kilometre pumping line from the coast (Los Abrigos and La Mareta) to the Ensenada Pelada treatment and pumping station. The article places the works within the Cabildo de Tenerife "zero discharge" strategy and describes Granadilla as a municipality particularly affected by discharges to the sea.

The article also mentions other works under way (Montaña Reverón in Arona, the Buenos Aires extension in Santa Cruz and the new Punta Brava plant in Puerto de la Cruz) and a joint Acuaes-Cabildo investment of 233.5 million euros. This action does not in itself imply any change in current bathing-water quality.

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.

The Cabildo approved €33.6 million to advance six major hydraulic infrastructure projects across Tenerife, including sanitation measures intended to reduce wastewater discharges.

This infrastructure action does not in itself imply any change in current bathing-water quality.

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.
