The GUADIARO wastewater treatment plant is located in San Roque, in the Campo de Gibraltar region of Andalucía, Spain. It serves a population of approximately 4,000 people, making it a small agglomeration under EU classification. The plant is situated near the coastal area of Guadiaro, close to the Mediterranean Sea. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into coastal waters. The designed capacity is 3,000 m³/day, and the current discharge volume is 724.99 m³/day, indicating operational capacity well within design limits. As a coastal plant, it must comply with additional requirements to protect marine environments. The treated effluent is discharged into the Mediterranean Sea via the Guadiaro River estuary. The area supports diverse marine life and is part of the Alboran Sea ecosystem, which is an important migratory corridor for marine species. The plant's operation helps maintain water quality in the coastal zone, supporting tourism and local fisheries.
Environmental context
The GUADIARO plant discharges into the Guadiaro River, which flows into the Mediterranean Sea at the Bay of Gibraltar. This coastal area is ecologically sensitive, supporting seagrass meadows and diverse fish populations. The Alboran Sea is a key migratory route for cetaceans and sea turtles. The plant's secondary treatment helps reduce nutrient loads and protect the marine environment from eutrophication.
