Overview
Ruaes wastewater treatment plant serves the Braga area in Portugal, with a designed capacity of 1.00 and serving a population of 10,000. It operates under the EU Urban Waste Water Treatment Directive.
Ruaes is a wastewater treatment plant located in Braga, Portugal, serving a population of approximately 10,000. The facility is situated in the northern region of the country, within the municipality of Braga, and plays a key role in managing local wastewater. As a Portuguese facility, it 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 sensitive. The treated effluent from Ruaes ultimately discharges into the local watershed, which drains into the Atlantic Ocean via the Cávado River basin. This region supports diverse aquatic life and is important for water quality in the surrounding areas. The plant's operation helps protect downstream ecosystems and public health.
Environmental context
Ruaes discharges into the Cávado River basin, which flows westward to the Atlantic Ocean near Esposende. The river supports a variety of fish species and is used for recreation and agriculture. The downstream estuary is ecologically sensitive, providing habitat for migratory birds and aquatic life. Proper treatment is essential to maintain water quality in this coastal region.
