ANORA DOS TORRES Wastewater Treatment Plant, Dos Torres, Andalucía, Spain

ANORA DOS TORRES is a wastewater treatment plant located in Dos Torres, a municipality in the province of Córdoba, Andalucía, southern Spain. The plant serves a population of approximately 4,160 people, classifying it as a small agglomeration under Spanish and EU regulations. It operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from settlements of this size. As a secondary treatment facility, ANORA DOS TORRES employs biological processes to reduce organic matter and suspended solids, meeting the effluent quality standards set by the directive. The plant has a designed capacity of 4,160 population equivalents and treats an average daily flow of 753.99 cubic meters. However, Spanish plants are regulated under national water law (Real Decreto 509/1996) and monitored by regional authorities. The treated effluent from ANORA DOS TORRES is discharged into a local watercourse that ultimately drains into the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows southwest through Andalucía and empties into the Atlantic Ocean at the Gulf of Cádiz. The plant's operations help protect downstream aquatic ecosystems and support water quality in the region, which is important for agriculture and biodiversity.

The plant discharges into a tributary of the Guadalquivir River basin, which flows through Andalucía and into the Atlantic Ocean at the Gulf of Cádiz. The Guadalquivir supports diverse aquatic life and is a critical water resource for agriculture in the region. Secondary treatment ensures that the effluent meets standards to protect downstream ecosystems, including wetlands and estuaries that are ecologically sensitive.
