Moguer Wastewater Treatment Plant: Serving Moguer, Andalusia, Spain

The Moguer wastewater treatment plant serves the municipality of Moguer in the province of Huelva, Andalusia, Spain. Located in the Comarca Metropolitana de Huelva, the facility handles wastewater from a population of approximately 18,760 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a plant serving between 10,000 and 100,000 people, the facility is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum standard. The plant's designed capacity is 1.00 cubic meters per day, and it operates within Spain's national regulatory framework, which implements the directive through Royal Decree-Law 11/1995 and subsequent legislation. The treated effluent from the Moguer plant is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Tinto River or nearby coastal systems. The region's aquatic ecosystems support diverse marine life and are important for migratory bird species, making proper wastewater treatment essential for environmental protection.

The Moguer plant discharges into the Tinto River basin, which flows into the Atlantic Ocean near Huelva. This coastal area supports ecologically sensitive habitats, including salt marshes and estuaries that provide critical nursery grounds for fish and shellfish. The region's Mediterranean climate with seasonal rainfall patterns means that maintaining consistent treatment quality is vital to prevent nutrient loading and protect downstream marine biodiversity.
