Minglanilla Wastewater Treatment Plant | Castilla-La Mancha, Spain

The Minglanilla wastewater treatment plant is located in the town of Minglanilla, in the province of Cuenca, within the autonomous community of Castilla-La Mancha, Spain. It serves a population of approximately 3,738 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant processes an average daily wastewater volume of 593 cubic meters, reflecting the scale of the local community it serves. The treated effluent is discharged into a local watercourse that ultimately drains into the Júcar River basin, a significant hydrological system in eastern Spain. The Júcar River flows into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural water use along its course.

The plant discharges into a tributary of the Júcar River, which flows through the province of Cuenca and eventually reaches the Mediterranean Sea near Cullera. The Júcar basin supports irrigated agriculture and provides habitat for native fish species such as the Júcar nase (Parachondrostoma turiense). The region's semi-arid climate makes water quality management critical for downstream ecological health and human use.
