Overview
Campo wastewater treatment plant serves Valongo, Portugal, with a designed capacity of 1.00 and a population equivalent of 46,000. It operates under the EU Urban Waste Water Treatment Directive.
Campo wastewater treatment plant is located in Valongo, within the Porto district of northern Portugal. The facility serves a population equivalent of 46,000, classifying it as a medium agglomeration under EU regulations. As a Portuguese plant, Campo operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Portugal has implemented the directive through national legislation, with regulatory oversight typically provided by the Portuguese Environment Agency (APA). The plant discharges treated wastewater into the local watershed, which ultimately drains into the Douro River basin. The Douro River flows westward through Porto and into the Atlantic Ocean. This river system supports diverse aquatic life and is an important ecological corridor in northern Portugal. The treatment plant plays a key role in protecting water quality in this region.
Environmental context
Campo's treated effluent enters the Douro River basin, which flows through the Porto region and discharges into the Atlantic Ocean. The Douro River supports diverse aquatic ecosystems, including fish species such as the Iberian barbel and nase. The watershed is influenced by both urban and agricultural runoff, making wastewater treatment critical for maintaining downstream water quality and ecological health.
