Tarazona Wastewater Treatment Plant - Serving Tarazona, Aragón, Spain

The Tarazona wastewater treatment plant is located in the municipality of Tarazona, in the province of Zaragoza, Aragón, Spain. It serves a population equivalent of 34,440, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. As a Spanish facility, the plant 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 advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and European water quality objectives. The treated effluent from the Tarazona plant is discharged into the local water system, which ultimately drains into the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea. The plant plays a crucial role in protecting the water quality of the Ebro basin and supporting the ecological health of downstream aquatic environments.

The Tarazona plant discharges into the Ebro River basin, which flows through northeastern Spain and empties into the Mediterranean Sea. The Ebro River supports diverse aquatic life and is an important ecological corridor. The plant's operations help maintain water quality in the basin, reducing nutrient and pollutant loads that could impact downstream ecosystems and the marine environment.
