Mogadouro Zona Norte Wastewater Treatment Plant, Mogadouro, Portugal

Mogadouro Zona Norte is a wastewater treatment plant located in Mogadouro, a town in the Bragança District of northern Portugal. The plant serves a population of 2,500 and is part of the municipal wastewater infrastructure for the region. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 m³/day and an average daily discharge of 416.83 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Douro River basin. The Douro River flows westward through Portugal and empties into the Atlantic Ocean near Porto. The plant plays a key role in protecting the water quality of the Douro basin, which supports diverse aquatic life and is important for agriculture and tourism in the region.

The plant discharges into the Douro River basin, which flows into the Atlantic Ocean. The Douro is one of the major rivers of the Iberian Peninsula, supporting a variety of fish species and providing water for irrigation and drinking. The plant's secondary treatment helps reduce organic pollutants and nutrients, protecting downstream ecosystems and water quality.
