Vila Pouca de Cernache Wastewater Treatment Plant, Condeixa-a-Nova, Portugal

Vila Pouca de Cernache is a wastewater treatment plant located in Condeixa-a-Nova, Coimbra District, Portugal. It serves a population of approximately 5,600 people, placing it in the small-to-medium agglomeration category under Portuguese and EU regulations. The plant is situated inland, more than 10 km from the coast, and operates under Portugal's implementation of the EU Urban Waste Water Treatment Directive. The plant employs advanced treatment processes, going beyond the secondary treatment standard typically required for agglomerations of this size under the EU Urban Waste Water Treatment Directive (91/271/EEC). Its designed capacity is 7,250 cubic meters per day, with an average daily discharge volume of 933.69 cubic meters, indicating significant spare capacity. The plant is part of Portugal's municipal wastewater infrastructure, managed by local authorities. 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's advanced treatment helps protect water quality in this ecologically important watershed.

The plant discharges into the Mondego River basin, which flows through central Portugal and empties into the Atlantic Ocean near Figueira da Foz. The Mondego River supports a variety of aquatic life, including the critically endangered European eel and other migratory fish. The advanced treatment at Vila Pouca de Cernache reduces nutrient loads and pollutants, helping to maintain the ecological health of the river and its downstream estuary, which is an important area for birdlife and fisheries.
