The ENCINASOLA wastewater treatment plant is located in Encinasola, a municipality in the Sierra de Huelva region of Andalucía, Spain. Designed to serve a population of 1,772, the plant provided secondary treatment before its closure. The facility had a designed capacity of 2,559 cubic meters per day and discharged an average volume of 321.17 cubic meters per day. As a secondary treatment plant in Spain, ENCINASOLA operated under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive aims to protect the environment from the adverse effects of untreated wastewater discharges. The plant's discharge likely entered local watercourses in the Sierra de Huelva region, which ultimately drain into the Atlantic Ocean via the Guadiana River basin. The area is ecologically sensitive, supporting diverse aquatic life and contributing to the overall health of the regional watershed.
Environmental context
The treated effluent from ENCINASOLA would have entered local streams in the Sierra de Huelva, part of the Guadiana River basin. The Guadiana River flows through southwestern Spain and Portugal before emptying into the Gulf of Cadiz in the Atlantic Ocean. This watershed supports a variety of aquatic species and is important for regional biodiversity, including migratory fish populations.
