PROVENCIO EL Wastewater Treatment Plant, El Provencio, Castilla-La Mancha

PROVENCIO EL is a municipal wastewater treatment plant located in El Provencio, a town in the Castilla-La Mancha region of Spain. The plant serves a population of 3,609, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a secondary treatment facility, PROVENCIO EL provides biological treatment to remove organic matter and suspended solids, meeting the standard requirements for inland plants under the UWWTD. The plant's treated effluent likely flows into local streams that drain into the Guadiana River basin, which ultimately reaches the Gulf of Cádiz. This inland location reduces direct marine impact, but proper treatment is essential to protect local water quality and aquatic ecosystems in the semi-arid landscape of La Mancha.

The plant discharges into the Guadiana River basin, one of the major river systems in the Iberian Peninsula, which flows southwest to the Gulf of Cádiz. The region's semi-arid climate means that treated wastewater is a critical resource for maintaining streamflow and supporting aquatic life, including fish species adapted to seasonal water availability.
