Overview
CALAMONTE wastewater treatment plant serves the Mérida area in Extremadura, Spain. It treats wastewater from approximately 7,200 people under EU regulatory standards.
The CALAMONTE wastewater treatment plant is located in Mérida, within the autonomous community of Extremadura, Spain. It serves a population of around 7,200 people, classifying it as a small to medium agglomeration under EU classification. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. As a Spanish facility, the plant operates under 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 discharge enters sensitive areas. The plant is expected to comply with these standards to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadiana River basin. The Guadiana River flows westward through Extremadura and into the Gulf of Cádiz (Atlantic Ocean). This river system supports diverse aquatic life and is important for regional agriculture and biodiversity. The plant's operation helps maintain the ecological health of this downstream environment.
Environmental context
The CALAMONTE plant discharges into the Guadiana River basin, which flows through Extremadura and into the Gulf of Cádiz in the Atlantic Ocean. The Guadiana River supports a variety of fish species and provides habitat for migratory birds. The region's Mediterranean climate with seasonal droughts makes consistent wastewater treatment crucial for maintaining river flow and water quality, especially during dry periods.
