RINCON DE SOTO Wastewater Treatment Plant, Rincón de Soto, La Rioja, Spain

The RINCON DE SOTO wastewater treatment plant is located in Rincón de Soto, a municipality in the autonomous community of La Rioja, Spain. The plant serves a population of around 8,312 residents, classifying it as a small to medium agglomeration under EU classification. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive ensures that wastewater is treated to protect receiving water bodies and public health. The plant discharges treated effluent into the local watershed, which ultimately drains into the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant's treated effluent enters the local drainage network, which flows into the Ebro River, the largest river in Spain by discharge volume. The Ebro River supports diverse aquatic life and is an important ecological corridor in northeastern Spain. The plant's treatment helps maintain water quality in the Ebro basin, which ultimately reaches the Mediterranean Sea, a semi-enclosed sea with sensitive marine ecosystems.
