Overview
Ericeira wastewater treatment plant serves Mafra, Portugal, with a designed capacity of 1.00 and a population equivalent of 25,300. It operates under EU Urban Waste Water Treatment Directive 91/271/EEC.
The Ericeira wastewater treatment plant is located in Santo Isidoro, Mafra, in the Lisbon district of Portugal. It serves a population of approximately 25,300 people and has a designed capacity of 1.00 (likely in thousands of cubic meters per day or similar unit). The plant is situated within 50 km of the coast, indicating its discharge may influence coastal waters. As a facility in Portugal, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size (between 10,000 and 150,000 population equivalent). For sensitive areas, tertiary treatment may be mandated. The regulatory framework ensures compliance with European standards. The plant's treated effluent likely discharges into local watercourses that flow to the Atlantic Ocean, given its proximity to the coast. The plant plays a key role in protecting the coastal environment and supporting the region's water quality objectives.
Environmental context
