Talaván Wastewater Treatment Plant - Secondary Treatment in Extremadura, Spain

The Talaván wastewater treatment plant is located in the municipality of Talaván, in the province of Cáceres, Extremadura, Spain. It serves a population of approximately 2,000 residents, making it a small-scale facility within the region's wastewater infrastructure. The plant is situated inland, away from coastal areas, and its operations are part of the broader water management system in the Tagus River basin. The plant operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The designed capacity of 2,000 m³/day aligns with the population served, and the reported discharge volume of 362.49 m³/day indicates that the plant operates well below its maximum capacity, allowing for future growth or seasonal variations. The treated effluent is discharged into the local water system, which ultimately drains into the Tagus River, one of the longest rivers in the Iberian Peninsula. The Tagus flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The plant's operations help protect the ecological health of the Tagus basin, which supports diverse aquatic life and provides water for agriculture and human consumption downstream.

The Talaván WWTP discharges into the Tagus River basin, which flows through central Spain and Portugal to the Atlantic Ocean. The Tagus is a vital water resource for the region, supporting irrigation, drinking water supply, and a variety of fish species. The plant's secondary treatment helps reduce organic pollution and nutrient loads, contributing to the ecological balance of the river and its downstream estuary.
