Overview
Gaia Litoral is a major wastewater treatment plant serving 250,000 people in Valbom, Portugal. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
Gaia Litoral is a wastewater treatment plant located in Valbom, Gondomar, in the Porto district of Portugal. It serves a population of approximately 250,000 people, classifying it as a large agglomeration under EU regulations. The plant is situated near the Douro River estuary, an ecologically important area. As a large agglomeration, Gaia Litoral is required to meet the standards of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum, and tertiary treatment if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating significant infrastructure to handle the region's wastewater. The plant's treated effluent likely discharges into the Douro River, which flows into the Atlantic Ocean near Porto. This coastal discharge point requires careful management to protect marine ecosystems and comply with the EU Water Framework Directive. The plant plays a crucial role in maintaining water quality in the Douro estuary, which supports diverse aquatic life and is important for local fisheries and tourism.
