LAS NAVAS DE LA CONCEPCION Wastewater Treatment Plant, Hornachuelos, Andalucía

LAS NAVAS DE LA CONCEPCION is a wastewater treatment plant located in the Cerro Miravete area of Hornachuelos, in the province of Córdoba, Andalucía, Spain. It serves a population of 3,610 and has a designed capacity of 4,000 m³/day, with a discharge volume of 654.30 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. As a secondary treatment facility, the plant uses biological processes to remove organic matter and suspended solids, meeting the effluent quality standards set by Spanish regulations. The plant is operated as part of the municipal wastewater infrastructure for Hornachuelos and surrounding areas, ensuring compliance with national and EU environmental standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadalquivir River basin, one of the most important river systems in southern Spain. The Guadalquivir flows through Andalucía and discharges into the Atlantic Ocean near Sanlúcar de Barrameda. The plant plays a key role in protecting the ecological health of the region's water bodies, supporting aquatic life and downstream ecosystems.

The plant discharges into the Guadalquivir River basin, which flows through Andalucía and empties into the Atlantic Ocean. The Guadalquivir supports diverse aquatic life and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting the river's ecological balance and downstream coastal waters.
