Summary

Greece’s Law 3983/2011 implements the EU Water Framework Directive, requiring River Basin Management Plans, water-use permits, pollution controls, and monitoring of ecological status. Industries, farmers, and municipalities must follow abstraction limits and discharge conditions. Enforcement targets illegal wells, untreated wastewater, and over-exploitation. The law is the main framework for sustainable water governance in Greece.

Details

Jurisdictions
  • Greece
Mandatory for

Binding for water users, municipalities, industries and agricultural operators.

They must:

Obtain water-use or discharge permits.

Follow conditions on abstraction limits, pollution controls and monitoring.

Comply with measures set in River Basin Plans, including restrictions in over-exploited aquifers.

Maintain records and allow inspections by water authorities.

Exemptions

Exceptions:

Small-volume agricultural abstractions may fall under simplified procedures.

Temporary exemptions apply during droughts or emergencies, under strict conditions.

What’s Required

Law 3983/2011 transposes the EU Water Framework Directive into Greek law and establishes a comprehensive water-resources management system.

Key obligations:

  • Preparation and regular revision of River Basin Management Plans covering all Greek water districts.

  • Monitoring of surface and groundwater status and classification into ecological and chemical categories.

  • Measures to prevent deterioration and ensure achievement of “good status”.

  • Regulation of water abstraction, discharge permits, and pollution-prevention measures.

  • Requirements for public participation in water planning and consultation procedures.

Important Deadlines

  • First River Basin Plans adopted in the early 2010s, revised in 2017–2018, and again for the 2022–2027 cycle.

  • Permits for abstractions and discharges must align with river basin objectives.

Current Status

Law 3983/2011 is the primary legal foundation for Greek water management. Implementation challenges remain in groundwater over-abstraction, agricultural pollution, and infrastructure gaps, but the regulatory framework is fully active and updated.

Penalties

  • Fines for non-permitted abstractions or discharges.

  • Administrative sanctions for pollution incidents.

  • Suspension of water-use rights for repeated violations.

Examples of Known Violations

  • Illegal irrigation wells are operating without permits.

  • Industrial operators are discharging wastewater without proper treatment.

  • Municipal systems are failing to meet effluent standards.
