ETAR del Polígono Industrial del Valle de Güímar - Arafo, Tenerife Wastewater Treatment Plant

ETAR del Polígono Industrial del Valle de Güímar is a wastewater treatment plant located in the industrial zone of Valle de Güímar, in the municipality of Arafo, on the island of Tenerife, Canary Islands, Spain. The plant serves a population equivalent of 9,729, primarily treating industrial wastewater from the surrounding industrial park. Its location on the eastern coast of Tenerife places it within 50 km of the coast, with potential discharge into the Atlantic Ocean. As a Spanish facility, the plant operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 2,000 and 10,000, the directive requires secondary treatment as a minimum. The regulatory framework ensures that the plant meets effluent standards appropriate for its scale and receiving environment. The plant's treated effluent likely discharges into the Atlantic Ocean via a coastal outfall, given its proximity to the coast. The Canary Islands are a biodiversity hotspot, and the surrounding marine environment supports sensitive ecosystems, including seagrass meadows and coral reefs. Proper treatment is essential to protect these habitats from nutrient pollution and industrial contaminants. The plant plays a key role in managing wastewater from the industrial park, safeguarding both local groundwater and coastal waters.

The plant is located on the eastern coast of Tenerife, within the Canary Islands archipelago. Treated wastewater likely discharges into the Atlantic Ocean, which supports diverse marine life including sea turtles, cetaceans, and endemic fish species. The coastal waters near Valle de Güímar are part of a region known for its volcanic coastline and rich marine biodiversity. Protecting this environment from nutrient enrichment and industrial pollutants is critical for maintaining water quality and ecosystem health.
