VILLANUEVA DE LOS CASTILLEJOS EL ALMENDRO is a wastewater treatment plant located in Villanueva de los Castillejos, in the province of Huelva, Andalucía, Spain. The plant serves a population of 5,531, classifying it as a small agglomeration under EU regulations. It is situated inland, more than 50 km from the coast, and its designed capacity is 1.00 (likely in cubic meters per day or similar units). As a Spanish facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures appropriate standards are met. The plant's treated effluent likely discharges into a local watercourse that flows through the Andévalo region, eventually reaching the Atlantic Ocean via the Guadiana River or other nearby rivers. The surrounding area is characterized by Mediterranean climate and rural landscapes, with agriculture and mining activities in the region. Proper wastewater treatment is essential to protect local water quality and downstream ecosystems.
Environmental context
The plant is located in the Andévalo region of Huelva, within the drainage basin of the Guadiana River, which flows into the Atlantic Ocean at the Gulf of Cádiz. The area supports diverse aquatic life and is important for migratory birds. The Guadiana River estuary is ecologically sensitive, and treated wastewater discharge must meet standards to prevent eutrophication and protect biodiversity.
