Prado Wastewater Treatment Plant, Vila de Prado, Portugal - Closed Facility

Prado wastewater treatment plant is located in Vila de Prado, a parish in the municipality of Vila Verde, Braga district, northern Portugal. The facility was designed to serve the local population and is now closed. It operated with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive for inland freshwater discharges. As a closed plant, Prado no longer processes wastewater. Its designed capacity of 2,133 m³/day indicates it was a medium-scale facility. Under Portuguese regulations, such plants typically fall under the national water authority's permitting system, which aligns with EU directives. The plant's closure may reflect upgrades or consolidation of regional treatment infrastructure. It is located inland, more than 10 km from the coast. The area drains into the Cávado River basin, which flows into the Atlantic Ocean near Esposende. The Cávado River supports diverse aquatic life and is important for regional water supply and agriculture.
