Overview
GALAROZA wastewater treatment plant serves the town of Galaroza in Andalucía, Spain, treating wastewater for approximately 2,625 residents with secondary treatment.
The GALAROZA wastewater treatment plant is located in the Sierra de Huelva region of Andalucía, Spain, serving the town of Galaroza. It is a municipal facility designed to handle the wastewater of around 2,625 residents, reflecting a small agglomeration scale typical of rural Andalusian communities. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater or estuaries. The facility has a designed capacity of 2,625 cubic meters per day and reports a discharge volume of 475.77 cubic meters per day, indicating operational headroom. The treated effluent is discharged into local watercourses that drain into the Atlantic Ocean via the Guadiana River basin. The Sierra de Huelva area is ecologically sensitive, supporting Mediterranean forest and riverine habitats. The plant's secondary treatment helps protect these ecosystems from organic pollution and nutrient loading.
Environmental context
The plant discharges into small streams that flow into the Guadiana River basin, which ultimately reaches the Gulf of Cádiz in the Atlantic Ocean. The Sierra de Huelva region features Mediterranean forests and rivers that support diverse aquatic life, including native fish and amphibians. Secondary treatment reduces biochemical oxygen demand and suspended solids, mitigating eutrophication risks in downstream water bodies.
