EDAR Golf del Sur Wastewater Treatment Plant, San Miguel de Abona, Tenerife

EDAR Golf del Sur is a wastewater treatment facility located in the Golf del Sur area of San Miguel de Abona, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of approximately 21,574, placing it in the medium agglomeration category under EU regulations. Its location in a popular tourist region means it plays a key role in managing wastewater from both residential and hospitality sectors. As a Spanish facility, EDAR Golf del Sur operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires at least secondary treatment, with more stringent requirements if the discharge enters sensitive areas. The plant's designed capacity is 1.00 cubic hectometer per year, indicating its scale relative to the population served. The plant's treated effluent is discharged into the Atlantic Ocean, given its proximity to the coast of Tenerife. The Canary Islands' marine environment supports diverse ecosystems, including seagrass meadows and coral communities, making proper wastewater treatment essential for protecting coastal water quality and marine biodiversity.

The plant discharges into the Atlantic Ocean near the southern coast of Tenerife. This coastal region supports ecologically sensitive marine habitats, including seagrass beds and rocky reef communities that provide nursery grounds for fish. The Canary Islands' waters are part of the Canary Current Large Marine Ecosystem, which sustains diverse pelagic and benthic species. Proper treatment is critical to prevent nutrient enrichment and protect the oligotrophic conditions typical of subtropical oceanic islands.
