Overview
ALMADEN CHILLON wastewater treatment plant serves Chillón, Castilla-La Mancha, Spain, with a population of 17,900. It operates under EU regulations for medium agglomerations.
ALMADEN CHILLON is a wastewater treatment plant located in Chillón, a municipality in the province of Ciudad Real, Castilla-La Mancha, Spain. The plant serves a population of approximately 17,900, classifying it as a medium agglomeration under EU standards. Its location in inland Spain places it within the Guadiana river basin, a major hydrological system. As a facility in an EU member state, ALMADEN CHILLON is subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The regulatory framework ensures compliance with discharge standards to protect receiving waters. The plant's treated effluent likely discharges into a tributary of the Guadiana River, which flows westward through Extremadura and into the Atlantic Ocean at the Gulf of Cádiz. This river system supports diverse aquatic life and is important for irrigation and regional water supply. Proper treatment is essential to prevent nutrient pollution and maintain water quality in this semi-arid region.
Environmental context
ALMADEN CHILLON discharges into the Guadiana River basin, which drains into the Atlantic Ocean via the Gulf of Cádiz. The Guadiana is a vital water resource in a semi-arid climate, supporting agriculture and wetlands of ecological significance. Downstream ecosystems include the Tablas de Daimiel National Park, a floodplain wetland that relies on groundwater and river flows. Effective wastewater treatment helps prevent eutrophication and protects biodiversity in this sensitive environment.
