ETAR de San Andres is a municipal wastewater treatment plant located in the Anaga district of Santa Cruz de Tenerife, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of 4,618 and has a designed capacity of 10,000 m³/day, with an average discharge volume of 837 m³/day. The plant provides primary treatment, which involves physical processes such as sedimentation to remove suspended solids. As a small agglomeration in Spain, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into coastal waters. The plant's coastal location means it must meet specific standards to protect marine environments. The treated effluent is discharged into the Atlantic Ocean near the northeastern coast of Tenerife. The surrounding waters are part of the Macaronesian marine region, known for its high biodiversity and endemic species. The discharge area is near the Anaga Rural Park, a protected landscape with significant ecological value, supporting coastal and marine habitats.
Environmental context
The plant discharges into the Atlantic Ocean off the northeastern coast of Tenerife, part of the Canary Current Large Marine Ecosystem. This area supports diverse marine life, including sea turtles, cetaceans, and endemic fish species. The nearby Anaga Rural Park features laurel forests and coastal cliffs, with the marine environment serving as a migratory corridor for seabirds and marine mammals. The discharge must comply with EU standards to minimize nutrient loading and protect sensitive coastal ecosystems.
