NUEVA JARILLA Wastewater Treatment Plant, Jerez de la Frontera, Andalucía

NUEVA JARILLA is a former wastewater treatment plant located in Jerez de la Frontera, within the Andalucía region of southern Spain. It served a small population of 2,075 people, reflecting its role in a rural or peri-urban community. The plant is now closed, and its operational history provides context for local wastewater management. As a secondary treatment facility, NUEVA JARILLA would have met the basic requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant had a designed capacity of 2,100 cubic meters per day, with a recorded discharge volume of 376.09 cubic meters per day, indicating it operated well below capacity before closure. The plant's discharge likely entered local watercourses that drain into the Guadalquivir River basin or nearby coastal areas, given its proximity to the Atlantic coast (within 50 km). The closure of this plant may have shifted treatment responsibilities to larger regional facilities, impacting local water quality and ecosystem health.

The plant is located inland in Andalucía, within 50 km of the Atlantic coast. Its treated effluent would have flowed into local streams and rivers, eventually reaching the Guadalquivir River basin or directly to the Gulf of Cádiz. This region supports diverse aquatic life and is important for migratory birds. The closure of the plant may have reduced local nutrient loads but also highlights the need for continued monitoring of downstream water quality.
