NOBLEJAS Wastewater Treatment Plant, Noblejas, Castilla-La Mancha, Spain

The NOBLEJAS wastewater treatment plant is located in Noblejas, a town in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of approximately 7,318 residents, reflecting its role in managing municipal wastewater for this inland community. The plant employs advanced treatment processes, which go beyond the secondary treatment standards typically required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive mandates appropriate treatment, and the advanced level here indicates a higher degree of nutrient removal or polishing, likely to protect sensitive receiving waters. The treated effluent is discharged at a rate of 975.00 cubic meters per day. The plant's inland location in the Tagus River basin suggests that discharge ultimately flows into the Tagus River system, which drains westward through Portugal to the Atlantic Ocean. The advanced treatment helps safeguard local streams and the broader river ecosystem from nutrient pollution.

The plant discharges into the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows from its source in the Montes Universales through central Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The river supports diverse aquatic life and is a critical water resource for agriculture and urban areas. Advanced treatment at NOBLEJAS reduces nutrient loads, protecting downstream water quality and preventing eutrophication in sensitive stretches of the river and its estuary.
