ILLA DA TOXA EDAR INDUSTRIAL - Advanced Wastewater Treatment Plant in A Toxa, Galicia, Spain

ILLA DA TOXA EDAR INDUSTRIAL is a wastewater treatment plant located in A Toxa, a coastal town in the province of Pontevedra, Galicia, Spain. The plant serves a population of 1,110 and is designed to handle up to 4,000 m³/day of wastewater. It is situated near the Atlantic coast, within 10 km of the shoreline, and its operations are subject to Spanish and European Union environmental regulations. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive coastal waters. Although the plant is currently listed as closed, its infrastructure reflects the standards expected for facilities in the region. The treated effluent from the plant likely discharges into the Atlantic Ocean via the Ría de Arousa, a coastal inlet known for its rich marine biodiversity and shellfish production. The Ría de Arousa is part of the Galician Rías Baixas, an ecologically sensitive area that supports important fisheries and tourism. The advanced treatment helps minimize nutrient loading and protect the marine environment.

The plant is located on the Atlantic coast of Galicia, within the Ría de Arousa estuary system. This estuary is a productive marine ecosystem supporting shellfish beds, bird populations, and diverse aquatic life. The treated wastewater likely discharges into the Ría de Arousa, which connects to the Atlantic Ocean. The advanced treatment level is crucial for protecting water quality in this ecologically sensitive coastal area, where nutrient pollution can lead to eutrophication and harm to shellfish fisheries.
