LIETOR Wastewater Treatment Plant, Liétor, Castilla-La Mancha, Spain

LIETOR is a wastewater treatment plant located in Liétor, a municipality in the province of Albacete, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of approximately 3,090 residents, reflecting its role in managing domestic wastewater for this small inland community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. As a facility in Spain, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and the sensitivity of receiving waters. For a plant of this size, advanced treatment aligns with best practices for environmental protection. The treated wastewater is discharged into local watercourses that eventually drain into the Segura River basin, which flows into the Mediterranean Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's water resources.

The plant discharges into the Segura River basin, which flows through southeastern Spain and empties into the Mediterranean Sea near Guardamar del Segura. The Segura River supports diverse aquatic life and is an important water source for agriculture and urban areas. Advanced treatment at LIETOR reduces nutrient loads, helping to prevent eutrophication in downstream reservoirs and coastal waters.
