Miranda do Corvo Wastewater Treatment Plant | Coimbra District, Portugal

The Miranda do Corvo wastewater treatment plant is located in the town of Miranda do Corvo, within the Coimbra District of central Portugal. The facility serves a population of approximately 7,580 residents, classifying it as a small to medium agglomeration under Portuguese and EU wastewater regulations. As a plant in Portugal, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into freshwater. The plant's treatment processes and capacity details are not publicly available, but the regulatory framework ensures compliance with national standards for effluent quality. The treated effluent is discharged into local watercourses that drain into the Mondego River basin, eventually reaching the Atlantic Ocean near Figueira da Foz. The Mondego River is the longest river entirely within Portugal and supports diverse aquatic ecosystems, including migratory fish species. The plant plays a key role in protecting water quality in this important watershed.

The plant discharges into the Mondego River basin, which flows westward through central Portugal to the Atlantic Ocean. The Mondego River supports a variety of freshwater habitats and is important for biodiversity, including native fish populations. Downstream, the estuary near Figueira da Foz provides critical nursery grounds for marine species. Effective wastewater treatment is essential to prevent nutrient enrichment and maintain ecological balance in this river system.
