NOEZ Wastewater Treatment Plant, Casasbuenas, Castilla-La Mancha

NOEZ is a wastewater treatment plant located near Casasbuenas, in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a small population of approximately 3,000 people, reflecting its role in a rural or semi-rural community. Its location along the Carretera de Noez a Casasbuenas places it within the inland region of central Spain. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically implemented to protect sensitive receiving environments or to meet stringent local discharge standards. The plant discharges 350 cubic meters of treated wastewater daily, indicating a modest operational scale consistent with the population served. The treated effluent from NOEZ likely flows into local streams that eventually drain into the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River ultimately reaches the Atlantic Ocean near Lisbon. The advanced treatment helps safeguard downstream aquatic ecosystems and supports water quality in the region, which is characterized by a Mediterranean climate with seasonal water scarcity.

NOEZ discharges treated wastewater into local watercourses that are part of the Tagus River basin. The Tagus River flows westward through Spain and Portugal, supporting diverse aquatic life and providing water for agriculture and urban use. The advanced treatment at NOEZ helps reduce nutrient and pollutant loads, protecting the ecological health of the downstream river system and the Atlantic coastal zone.
