SORBAS Wastewater Treatment Plant, Sorbas, Andalucía, Spain

The SORBAS wastewater treatment plant is located in Sorbas, a municipality in the province of Almería, Andalucía, Spain. Designed to serve a population of 1,374, the plant has a capacity of 2,000 m³/day and treats wastewater to secondary level. The plant is currently closed. As a secondary treatment facility in Spain, SORBAS operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The plant's design capacity of 2,000 m³/day corresponds to approximately 10,000 PE, placing it at the upper end of this category. Spanish regulations transpose the EU directive through Royal Decree 509/1996, which sets standards for discharge and treatment. The plant's treated effluent likely discharges into a local watercourse that flows into the Mediterranean Sea, as Sorbas is inland but within 50 km of the coast. The region's semi-arid climate means water resources are scarce, making wastewater treatment crucial for protecting downstream ecosystems and supporting agricultural reuse.

Sorbas is located in the Almería province, part of the Andalusian Mediterranean basin. The treated wastewater from the plant would have discharged into a local rambla (dry riverbed) that flows into the Mediterranean Sea. The coastal waters of Almería support diverse marine life, including seagrass meadows and fish species, and are important for tourism and fisheries. Proper treatment is essential to prevent nutrient pollution and protect these sensitive coastal ecosystems.
