Overview
Anca wastewater treatment plant in Cantanhede, Portugal, is a closed secondary treatment facility with a designed capacity of 2,768 m³/day. It served the local community before decommissioning.
Anca wastewater treatment plant is located in the parish of Ançã, within the municipality of Cantanhede, Coimbra District, Portugal. The facility, now closed, was designed to treat municipal wastewater from the local population. As a secondary treatment plant, it would have provided biological treatment to reduce organic matter and suspended solids before discharge. Although the plant is no longer operational, it was designed with a capacity of 2,768 m³ per day. In Portugal, wastewater treatment plants are regulated under national legislation transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on agglomeration size and receiving water sensitivity. Secondary treatment is the minimum required for freshwater discharges from agglomerations over 2,000 population equivalent. The plant's discharge would have entered a local watercourse within the Mondego River basin, which flows into the Atlantic Ocean near Figueira da Foz. The region's water bodies support diverse aquatic life and are important for agriculture and tourism. Improving efficiency and environmental protection.
Environmental context
The plant is located inland, approximately 50 km from the Atlantic coast, within the Mondego River watershed. The Mondego River is the longest river entirely within Portugal, flowing through Coimbra and discharging into the Atlantic near Figueira da Foz. The downstream environment includes estuarine habitats that support migratory fish species and diverse birdlife. The region's water quality is managed under the EU Water Framework Directive, aiming for good ecological status.
