Overview
ALCARRAS wastewater treatment plant serves Torres de Segre, Catalunya, Spain, with a population of 8,853. It operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this scale.
The ALCARRAS wastewater treatment plant is located in Torres de Segre, a municipality in the Segrià comarca of Catalunya, Spain. Serving a population of 8,853, the plant is part of the region's municipal wastewater infrastructure, managed under the regulatory framework of the European Union and Spanish national water laws. As an agglomeration serving fewer than 10,000 people, the plant falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment before discharge into inland waters. Plants of this scale typically employ secondary biological treatment to meet effluent quality standards. The population served indicates a moderate-scale facility. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Ebro River basin. The Ebro River is one of the most important rivers in Spain, flowing into the Mediterranean Sea. The plant plays a key role in protecting the water quality of the Segre River, a tributary of the Ebro, and the downstream ecosystems of the Ebro Delta, a region of high ecological value.
Environmental context

The Ebro River flows into the Mediterranean Sea via the Ebro Delta, an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. The plant's operations help maintain water quality in this watershed, which is vital for agriculture, recreation, and biodiversity in the region.
