ETAR de Radazul is a wastewater treatment facility located in El Rosario, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of about 9,593 people, classifying it as a small to medium agglomeration under Spanish and EU regulations. Its location in the coastal suburb of Radazul places it within the Santa Cruz de Tenerife metropolitan area. As a Spanish plant, ETAR de Radazul operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into coastal waters. For agglomerations of this size, secondary treatment is standard, with tertiary treatment possible if the receiving environment is sensitive. The plant's treated effluent discharges into the Atlantic Ocean near the southeastern coast of Tenerife. The coastal waters in this region support diverse marine life, including seagrass meadows and fish populations. Proper treatment is essential to protect water quality for tourism, recreation, and marine ecosystems in the Canary Islands.
Environmental context
ETAR de Radazul discharges treated wastewater into the Atlantic Ocean off the southeastern coast of Tenerife. The coastal waters are part of the Canary Current Large Marine Ecosystem, which supports rich biodiversity including cetaceans, sea turtles, and endemic fish species. The plant's proximity to the coast (within 50 km) means that effluent must meet stringent standards to prevent eutrophication and protect sensitive marine habitats, such as seagrass beds and rocky reefs that are important for local fisheries and tourism.
