ETAR de Los Llanos is a wastewater treatment plant located in the Los Llanos district of Santa Cruz de Tenerife, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population equivalent of 231,732, placing it in the large agglomeration category under European Union regulations. As a Spanish facility, ETAR de Los Llanos operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for all discharges from agglomerations over 15,000 population equivalent, and tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar units), and it is situated in a coastal region where treated effluent may be discharged into the Atlantic Ocean. The plant's location on Tenerife means its treated wastewater ultimately enters the Atlantic Ocean, contributing to the marine environment of the Canary Islands. The surrounding waters support diverse marine life, including cetaceans and sea turtles, making proper treatment essential for ecological health.
