Overview
Las Navas del Marqués wastewater treatment plant serves the municipality of Las Navas del Marqués in Ávila, Castilla y León, Spain. It treats wastewater from a population of approximately 22,832.
Las Navas del Marqués wastewater treatment plant is located in the municipality of Las Navas del Marqués, in the province of Ávila, within the autonomous community of Castilla y León, Spain. The plant serves a population of around 22,832, classifying it as a medium-sized agglomeration under Spanish and EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 10,000 and 150,000 are generally required to have secondary treatment, with more stringent requirements if the discharge is into sensitive areas. The regulatory framework ensures that facilities of this scale meet appropriate standards for effluent quality. The treated effluent is discharged into the local water environment, ultimately contributing to the Alberche River basin, which flows into the Tagus River and eventually reaches the Atlantic Ocean near Lisbon. The plant plays a key role in protecting the water quality of the Alberche River and the downstream Tagus ecosystem.
Environmental context
The plant discharges into the Alberche River basin, a tributary of the Tagus River, which flows westward across Spain and Portugal to the Atlantic Ocean. The Tagus River supports diverse aquatic life and is an important migratory corridor for fish species. The Alberche River itself is a key water resource for the region, providing irrigation and drinking water, and its ecological health is vital for local biodiversity.
