LANTEJUELA Wastewater Treatment Plant, La Lantejuela, Andalucía

LANTEJUELA is a wastewater treatment plant located in La Lantejuela, a municipality in the province of Seville, Andalucía, Spain. The plant serves a population equivalent of 6,063, placing it in the small agglomeration category under EU classification. It is situated inland, more than 50 km from the coast, and its operations are part of the regional water management infrastructure in southern Spain. As a Spanish facility, LANTEJUELA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. Spain has transposed these requirements into national legislation, and the plant's performance is monitored by regional authorities in Andalucía. The treated effluent from LANTEJUELA is discharged into local watercourses that ultimately drain into the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows westward through Andalucía and empties into the Gulf of Cádiz (Atlantic Ocean). The receiving waters support diverse aquatic life and are important for agriculture and biodiversity in the region.

LANTEJUELA's treated wastewater enters local streams that are part of the Guadalquivir River basin. The Guadalquivir River flows through Andalucía and discharges into the Gulf of Cádiz, an ecologically productive area of the Atlantic Ocean. The downstream environment includes wetlands and estuaries that provide critical habitat for migratory birds and fish species. The plant's operations help protect these sensitive ecosystems from nutrient pollution and other contaminants.
