Overview
Montelavar wastewater treatment plant serves Terrugem, Portugal, with a designed capacity of 1.00 and a population equivalent of 8,500. It operates under EU Urban Waste Water Treatment Directive standards.
Montelavar is a wastewater treatment plant located in Terrugem, within the Sintra municipality of the Lisbon district, Portugal. It serves a population equivalent of 8,500, classifying it as a small to medium agglomeration under EU regulations. The plant's designed capacity is 1.00, indicating its scale for local wastewater management. As a Portuguese facility, Montelavar 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 areas. The plant is expected to meet these regulatory standards to protect water quality. The plant's treated effluent likely discharges into local watercourses that flow into the Atlantic Ocean, given its proximity to the coast (within 50 km). The region's watershed includes small rivers draining the Sintra hills, supporting local ecosystems and eventually reaching the ocean. Proper treatment helps safeguard these aquatic environments and downstream coastal waters.
Environmental context
Montelavar's treated wastewater likely enters local streams that drain into the Tagus River estuary or directly into the Atlantic Ocean, given its coastal proximity. The receiving waters support diverse aquatic life and are important for regional biodiversity. Effective treatment is crucial to prevent nutrient pollution and protect downstream marine habitats, including those near the Lisbon coast.
