ALMAGRO BOLANOS Wastewater Treatment Plant, Almagro, Castilla-La Mancha, Spain

ALMAGRO BOLANOS is a wastewater treatment plant located in Almagro, within the province of Ciudad Real in the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 43,858, placing it in the medium agglomeration category under EU classification. Its location in the central Iberian Peninsula, inland and away from coastal areas, shapes its operational and environmental context. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment as a minimum. Spain has transposed this directive into national law, and plants like ALMAGRO BOLANOS are subject to regulatory oversight by the relevant water authority. The plant is expected to meet the directive's standards for biological treatment and, if discharging to sensitive areas, additional nutrient removal. The treated effluent from ALMAGRO BOLANOS likely discharges into a local watercourse within the Guadiana River basin, which ultimately flows into the Gulf of Cádiz (Atlantic Ocean). The region's semi-arid climate means that water resources are precious, and the plant plays a key role in protecting local streams and groundwater from pollution. Downstream ecosystems, including wetlands and agricultural areas, benefit from the plant's treatment efforts.

The plant is situated inland in the Guadiana River basin, which drains into the Atlantic Ocean via the Gulf of Cádiz. The Guadiana basin supports diverse aquatic habitats and is important for migratory birds. The region's Mediterranean-continental climate with low rainfall means that maintaining water quality in local streams is critical for both ecological health and human use, including irrigation.
