Campillo de Altobuey Wastewater Treatment Plant | Advanced Treatment in Castilla-La Mancha

Campillo de Altobuey wastewater treatment plant is located in the municipality of Campillo de Altobuey, in the province of Cuenca, Castilla-La Mancha, Spain. The plant serves a population of approximately 3,860 residents, reflecting the scale of a small agglomeration under EU classification. The plant 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. This level of treatment typically includes nutrient removal or other tertiary steps, ensuring high-quality effluent. The treated wastewater is discharged into the local hydrological network, which ultimately drains into the Júcar River basin. The Júcar River flows eastward to the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural water use in the region. The advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Júcar River basin, which flows into the Mediterranean Sea. The Júcar River supports irrigated agriculture and provides habitat for native fish species. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and the coastal zone.
