Overview
SOLANA LA wastewater treatment plant serves La Solana in Castilla-La Mancha, Spain, with a population equivalent of 28,560. The facility operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
SOLANA LA is a wastewater treatment plant located in La Solana, a municipality in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population equivalent of 28,560, placing it in the medium agglomeration category under EU classification. As a Spanish facility, SOLANA LA operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations between 10,000 and 150,000 population equivalent, the directive requires secondary treatment as a minimum, with more stringent treatment in sensitive areas. The plant's specific treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with European standards. The treated effluent from SOLANA LA is discharged into the local hydrological network, which ultimately drains into the Guadiana River basin. The Guadiana River flows westward through Castilla-La Mancha and Extremadura before reaching the Gulf of Cádiz in the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Guadiana basin, supporting both agricultural water use and aquatic ecosystems.
Environmental context
SOLANA LA discharges into the Guadiana River basin, one of Spain's major river systems. The Guadiana flows through the semi-arid La Mancha plain, where water resources are critical for irrigation and wetland conservation. Downstream, the river supports the Tablas de Daimiel National Park, a unique floodplain ecosystem. The plant's operations help maintain water quality in this sensitive basin, reducing nutrient loads that could otherwise contribute to eutrophication in the river and its receiving waters in the Gulf of Cádiz.
Frequently asked questions
SOLANA LA is located in La Solana, a municipality in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain.
The plant serves a population equivalent of 28,560, classifying it as a medium-sized agglomeration under EU wastewater treatment regulations.
The treated effluent from SOLANA LA is discharged into the local water network, which flows into the Guadiana River basin. The Guadiana River ultimately reaches the Gulf of Cádiz in the Atlantic Ocean.
As a Spanish plant, SOLANA LA operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of its size, the directive mandates secondary treatment, with additional requirements if the receiving waters are designated as sensitive areas.
In Spain, wastewater treatment plants serving populations between 10,000 and 150,000 typically provide at least secondary treatment, which includes biological processes to reduce organic matter and suspended solids. In sensitive areas, tertiary treatment for nutrient removal may also be required.
