Summary

Portugal’s Water Law and the Water Resources Use Regime require licences, authorisations or concessions for private uses of water resources, including abstraction, discharges and certain works or occupations in the public water domain. Operators must obtain the relevant title before starting activities and comply with permit conditions, monitoring, and reporting duties. Enforcement includes fines, suspension orders, and restoration obligations, with elevated exposure where groundwater or ecological status is affected. Non-compliance most often involves unlicensed abstraction or discharges, exceedance of licensed limits, or unauthorised works in water bodies and protection zones.

What’s Required

Portugal’s Water Law establishes the national framework for water protection and management, including rules for private uses of water resources subject to licensing. The Water Resources Use Regime operationalises permits and titles for water abstraction, discharge, and occupation of the public water domain. Key requirements include:

  • Water use that qualifies as “private use” requires a title (licence, authorisation, or concession), depending on the activity.

  • Permitting for water abstraction, discharges to water bodies, and certain works or occupations in the public water domain.

  • Compliance with conditions, monitoring, and reporting duties set by the permit.

  • Protection of ecological status and risk prevention for pollution incidents.

Important Deadlines

  • Before starting the activity, the relevant water use title must be obtained.

  • Continuous: compliance with permit conditions, monitoring, and reporting deadlines set in the title.

Current Status

Fully in force and implemented through APA and licensing systems, APA presents the Water Law as the basis for uses subject to licensing.

Penalties for Non-Compliance

  • Administrative fines for unlicensed abstraction, discharge, or occupation.

  • Orders to suspend activities, restore affected areas, and remediate damage.

  • Potential criminal exposure for serious water pollution incidents under broader environmental enforcement.

Examples of Known Violations

  • Water abstraction without a valid licence or beyond licensed quantities.

  • Discharges exceeding permit limits or operating without a discharge title.

  • Works in watercourses or protected zones without proper authorisation.
