Regulatory context

EU framework; national review pending. This is not an exhaustive review of applicable law.

European Union: urban wastewater treatment

Directive (EU) 2024/3019 sets phased requirements. Inventory design capacity is not the legally defined load and cannot by itself determine a facility's deadline.

  • Relevant load and agglomeration size, not just design capacity.
  • Receiving area, risk assessment, national transposition and individual permit.
  • Articles 7 and 8: tertiary and quaternary treatment; 150,000 p.e. is a load threshold, not a rule automatically applied to map design capacity.

References reviewed: 2026-11-06. Individual applicability: undetermined. This profile does not establish authorization or compliance.
