It serves a population of approximately 7,400 people, classifying it as a small agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the municipal wastewater infrastructure for the region. As a small-scale treatment plant in Portugal, ETAR Sul Aguada de Cima is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size.

The plant discharges treated wastewater into local watercourses that ultimately drain into the Atlantic Ocean via the Vouga River basin. The region's aquatic ecosystems benefit from regulated treatment, reducing nutrient loads and protecting downstream habitats. The facility plays a key role in maintaining water quality in the Águeda area, supporting both ecological health and public sanitation.
Environmental context
The plant's treated effluent flows into the Vouga River basin, which drains into the Ria de Aveiro lagoon and then the Atlantic Ocean. This coastal lagoon is an ecologically sensitive area supporting diverse aquatic life, including migratory fish and waterbirds. Proper treatment helps prevent eutrophication and protects the lagoon's biodiversity.
