Overview
CANDELEDA wastewater treatment plant serves the municipality of Candeleda in Ávila, Castilla y León, Spain. It handles a population equivalent of approximately 11,903 under the EU Urban Waste Water Treatment Directive.
CANDELEDA is a wastewater treatment plant located in Candeleda, a town in the province of Ávila, within the autonomous community of Castilla y León, Spain. The facility serves a population of approximately 11,903, placing it in the medium agglomeration category under EU regulations. As a Spanish plant, CANDELEDA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters a sensitive area. The plant is expected to meet these regulatory standards. The treated effluent from CANDELEDA likely discharges into a local watercourse that flows into the Tiétar River, a tributary of the Tagus River. The Tagus eventually reaches the Atlantic Ocean near Lisbon. The surrounding area is ecologically sensitive, supporting diverse aquatic life and serving as an important corridor for migratory birds.
Environmental context
The plant's discharge likely enters a tributary of the Tiétar River, which flows into the Tagus River, one of the Iberian Peninsula's major rivers. The Tagus basin supports diverse ecosystems, including riparian forests and wetlands that provide habitat for fish and bird species. The downstream environment benefits from the plant's treatment, which helps maintain water quality in this ecologically important watershed.
Frequently asked questions
The CANDELEDA wastewater treatment plant is located in Candeleda, a town in the province of Ávila, within the autonomous community of Castilla y León, Spain.
The plant serves a population equivalent of approximately 11,903, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent from CANDELEDA is likely discharged into a local watercourse that flows into the Tiétar River, a tributary of the Tagus River, which eventually reaches the Atlantic Ocean.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of 10,000 to 150,000 population equivalent, like CANDELEDA, are required to provide secondary treatment. If the receiving water is a sensitive area, more advanced treatment may be needed.
In Spain, plants serving this population size typically employ secondary biological treatment, such as activated sludge or trickling filters, to meet EU standards. Some may also include nutrient removal if discharging into sensitive areas.
