MAZARRON Wastewater Treatment Plant, Mazarrón, Región de Murcia, Spain

The MAZARRON wastewater treatment plant is a municipal facility serving the town of Mazarrón in the Región de Murcia, Spain. With a population equivalent of 69,661, it is classified as a medium-to-large agglomeration under EU regulations. The plant is situated in the Moreras area, near the Mediterranean coast. 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. For plants in sensitive coastal areas, such as the Mediterranean, tertiary treatment may be mandated to protect marine ecosystems. The designed capacity is 1. 00 (likely in cubic meters per day or similar units), indicating the plant's intended throughput. The treated effluent is discharged into the local environment, ultimately reaching the Mediterranean Sea. The region's semi-arid climate and coastal location make water quality management critical for tourism and marine biodiversity. The plant plays a key role in protecting the coastal waters of the Mar Menor and surrounding areas from nutrient pollution.

The plant discharges into the Mediterranean Sea via local watercourses in the Bajo Guadalentín region. The receiving waters support diverse marine life and are important for tourism and fisheries. The nearby Mar Menor is a hypersaline lagoon of ecological significance, and nutrient management is crucial to prevent eutrophication. The plant's coastal location requires advanced treatment to minimize environmental impact.
