TAMAMES Wastewater Treatment Plant, Tamames, Castilla y León, Spain

TAMAMES is a wastewater treatment plant located in Tamames, Salamanca, within the autonomous community of Castilla y León, Spain. The facility serves a population of approximately 3,318 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity of 3,318 m³/day aligns with the population served, and the current discharge volume of 300 m³/day indicates operational levels well within capacity. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, likely a tributary of the Tormes River, which flows into the Duero River and eventually reaches the Atlantic Ocean via the Douro estuary in Portugal. The plant plays a key role in protecting the local watershed from untreated sewage, supporting aquatic life and downstream water quality in the Duero basin.

The plant discharges into a local stream that feeds into the Tormes River, a major tributary of the Duero River. The Duero basin is one of the largest in the Iberian Peninsula, supporting diverse aquatic ecosystems and providing water for agriculture and human consumption. The downstream environment includes the Arribes del Duero Natural Park, a protected area known for its deep river canyons and birdlife. By providing secondary treatment, the plant helps reduce nutrient and organic pollution, safeguarding the ecological health of the river system.
