Urban WastewaterTreatment Directive
Obligations and milestones

Individual systems

Registration, inspection and evidence of an equivalent level of protection.

Back to the obligation overview
Topic context

What is changing and why preparation matters

Individual or other appropriate systems remain possible where a collecting system is not justified or feasible.

Their use is not unregulated: Member States must ensure registration, regular inspection and equivalent environmental and health protection.

Timeline

Obligations and their practical meaning

Each block has a permanent link. Always verify the exact scope against the agglomeration and plant profile and the final Czech implementation.

Preparation and planning

Register, inspect and document systems that provide an equivalent level of environmental and health protection.

Delivery: ongoing#individual-2028

Individual and other appropriate systems

Register, inspect and document systems that provide an equivalent level of environmental and health protection.

What this means in practice

Prepare geographically precise records of installations, responsible parties, inspections, maintenance and results; Czech legislation will assign the register and inspection roles.

  • Georeferenced register, inspection results and proof of equivalent protection.
  • Implementation period: 2027–2028.
  • Keep the evidence traceable and ready for reporting.

Scope and evidence

Who it applies to: Agglomerations using individual systems alone or alongside collecting systems.

Evidence: Georeferenced register, inspection results and proof of equivalent protection.

Why this step matters

Registration and control prevent decentralised solutions from becoming unmanaged pollution sources while retaining proportionate local options.

Legal context: Article 4(2)–(4).
