Vale de Tabuas is a wastewater treatment plant located in Figueiró dos Vinhos, in the Leiria district of central Portugal. It serves a population of approximately 5,300 people, making it a small to medium-sized facility within the country's municipal wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 5,400 m³/day, with an average discharge volume of 883.67 m³/day, indicating significant reserve capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the Zêzere River, a major tributary of the Tagus River. The Tagus flows westward through Portugal to the Atlantic Ocean near Lisbon. The plant's advanced treatment helps protect the Zêzere River and downstream ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant discharges into a small watercourse that flows into the Zêzere River, a key tributary of the Tagus River basin. The Tagus River is one of the longest rivers in the Iberian Peninsula, supporting diverse aquatic life and providing water for agriculture and urban use. The advanced treatment at Vale de Tabuas reduces the risk of eutrophication and protects the ecological health of the Zêzere and Tagus rivers, which are important for biodiversity and regional water quality.
