ALZIRA CARCAIXENT is a major wastewater treatment plant located in Carcaixent, in the Ribera Alta comarca of Valencia, Spain. Serving a population of over 200,000, it is classified as a large agglomeration under EU regulations, requiring robust treatment infrastructure to protect the local environment. As a plant of this scale in Spain, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary or tertiary treatment for agglomerations exceeding 150,000 population equivalent, especially in sensitive areas like the Mediterranean coast. The plant's designed capacity is 1.00 unit, indicating its significant role in regional wastewater management. The treated effluent likely discharges into the Júcar River basin or directly into the Mediterranean Sea, given the proximity to the coast. This discharge supports downstream ecosystems and agricultural water reuse, while also contributing to the ecological health of the Albufera de Valencia lagoon, a vital wetland area for migratory birds and aquatic life.
Environmental context
The plant's receiving water body is likely the Júcar River, which flows into the Mediterranean Sea near Carcaixent. The downstream environment includes the Albufera de Valencia, a coastal lagoon and ecologically sensitive area that supports diverse aquatic life and serves as an important migratory corridor for birds. The plant's treatment level is critical to preventing nutrient pollution and maintaining water quality in this fragile ecosystem.
