Overview
EPILA wastewater treatment plant serves Épila in Aragón, Spain, with a population of approximately 9,500. The facility operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
EPILA is a wastewater treatment plant located in Épila, a municipality in the province of Zaragoza, within the autonomous community of Aragón, Spain. The plant serves a population of around 9,500 people, placing it in the small-to-medium agglomeration category under EU classification. As a Spanish facility, EPILA operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum standard, with more stringent requirements if the discharge enters a sensitive area. Compliance with EU standards ensures a baseline level of treatment. The treated effluent from EPILA is discharged into the local watershed, which ultimately drains into the Ebro River basin. The Ebro River is one of the most important rivers in Spain, flowing into the Mediterranean Sea. The plant's operations contribute to protecting the ecological health of the Ebro River system and the downstream marine environment.
Environmental context
EPILA's treated wastewater discharges into the Ebro River basin, which flows through northeastern Spain and empties into the Mediterranean Sea via the Ebro Delta. The delta is an ecologically significant area that supports diverse aquatic life and migratory bird populations. The plant's treatment performance is critical for maintaining water quality in this sensitive downstream environment.
