VILLALPARDO VILLARTA EL HERRUMBLAR Wastewater Treatment Plant, Villarta, Spain

VILLALPARDO VILLARTA EL HERRUMBLAR is a wastewater treatment plant located in Villarta, within the province of Cuenca in the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of 7,380, placing it in the small-to-medium agglomeration category under Spanish and EU regulations. The facility employs advanced treatment processes, which go beyond the secondary treatment standard 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) or other tertiary steps, ensuring high-quality effluent before discharge. The treated wastewater is discharged into the local hydrological network, which ultimately drains into the Júcar River basin. The Júcar River flows eastward into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural water use in the region. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Júcar River basin, which flows through Castilla-La Mancha and the Valencian Community before reaching the Mediterranean Sea. The Júcar River supports irrigated agriculture, wetlands, and habitats for fish and bird species. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream reservoirs and coastal waters.
