What’s Required
Portugal regulates wastewater discharges through (1) national water-quality and emission rules and (2) the licensing of water uses, including discharges.
Key requirements include:
Decree-Law 236/98 sets quality standards, criteria, and objectives to protect the aquatic environment and includes rules covering wastewater discharges to water and soil.
Decree-Law 226-A/2007 establishes the regime for water resources use titles, which typically include licensing for abstractions and discharges with enforceable conditions.
Certain direct discharges into groundwater of hazardous substances are prohibited under the discharge controls discussed in legal practice summaries referencing Decree-Law 236/98.
APA operates licensing guidance and expectations for water uses and permitting.
Important Deadlines
Before discharge begins: obtain the applicable water use title (licence/authorisation) where required.
Continuous: monitoring, sampling, reporting, and compliance with emission limits and permit conditions (timelines set in titles).
Current Status
Both regimes are fully in force and form the backbone of discharge licensing and enforcement in Portugal.
Penalties for Non-Compliance
Administrative fines and corrective orders for unlicensed discharge or exceedance of permitted parameters.
Suspension of discharge permissions and restoration/remediation obligations for serious or repeated breaches.
Elevated exposure where prohibited discharges to groundwater occur.
Examples of Known Violations
Discharging without a valid water use title or beyond authorised volumes.
Exceedance of limit values and failure to comply with monitoring/reporting duties.
Prohibited direct discharge of certain hazardous substances into groundwater.
