The DAROCA wastewater treatment plant is located in Daroca, a town in the Campo de Daroca comarca of Zaragoza province, Aragón, Spain. The facility serves a population of approximately 4,549 and operates at a designed capacity of 7,100 m³/day, with an average discharge volume of 824.49 m³/day. As a secondary treatment plant, DAROCA meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in non-sensitive areas, which aligns with the plant's current treatment level. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream environment.
Environmental context
The DAROCA plant discharges into the Jiloca River, a tributary of the Jalón River, which flows into the Ebro River. The Ebro River basin supports diverse aquatic life and is an important agricultural and ecological corridor in northeastern Spain. The plant's secondary treatment helps reduce organic pollution and nutrient loads, safeguarding water quality in the downstream river system and ultimately the Mediterranean Sea.
