Overview
QUER wastewater treatment plant serves the town of Quer in Castilla-La Mancha, Spain. It provides advanced treatment for a population of approximately 1,000, discharging 305 m³/day.
QUER is a wastewater treatment plant located in the municipality of Quer, in the province of Guadalajara, Castilla-La Mancha, Spain. The facility serves a small population of around 1,000 residents, reflecting the rural character of the area. 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 ensures high-quality effluent suitable for sensitive environments. The treated wastewater is discharged into the local hydrological network, which ultimately drains into the Tagus River basin, one of the most important river systems in the Iberian Peninsula. The advanced treatment helps protect downstream water quality and aquatic ecosystems.
Environmental context
The plant's discharge enters the Tagus River basin, which flows westward through central Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The Tagus supports diverse aquatic life and provides water for agriculture, industry, and human consumption. Advanced treatment at QUER reduces nutrient loads and pollutants, contributing to the ecological health of this transboundary river system.
