Sensitive Areas for Eutrophication Under EU Directive 91/271/EEC

Polygon data representing eutrophication-sensitive areas reported by EU member states under Directive 91/271/EEC on urban wastewater treatment. The dataset includes information on agglomerations, wastewater treatment plants, and discharge points, reported to the European Commission in 2024 with a status date of December 2022. It is managed by the Executive Board of the Geographic Information Infrastructure of Spain (CODIIGE) for the Spanish Spatial Data Infrastructure.

Use Cases

• Map eutrophication-sensitive zones based on polygon geometry for environmental impact assessments.
• Analyze compliance with urban wastewater treatment regulations based on reported agglomeration and discharge point data.
• Integrate spatial data on sensitive areas into regional water quality models using the provided coordinate reference systems.

Strengths

• Data is reported under a specific EU Directive (91/271/EEC), providing a regulatory framework.
• Service supports multiple coordinate reference systems, including CRS:84, EPSG:4326, and several UTM zones for flexible integration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment.
