Urban Waste Water Directive Overview
- 16/12/2019 Publication of the Evaluation of the Urban Waste Water Treatment Directive. All information can be found here.
- 14/12/2017: Adoption of the 9th Commission Report on the implementation of the Urban Waste Water Treatment Directive. Significant progress has been achieved, but despite the high level of compliance a number of challenges remain, and the waste water sector continues to require significant investments to ensure sufficient collection and treatment.
In this section of the website you can find:
The Council Directive 91/271/EEC concerning urban waste-water treatment was adopted on 21 May 1991. Its objective is to protect the environment from the adverse effects of urban waste water discharges and discharges from certain industrial sectors (see Annex III of the Directive) and concerns the collection, treatment and discharge of:
- Domestic waste
- Mixture of waste water
- Waste water from certain industrial sectors (see Annex
III of the Directive)
This is illustrated in the figure below:

Four main principles are laid down in the Directive:
Specifically the Directive requires:
- The collection and treatment of waste water in all agglomerations of >2000 population equivalents (p.e.);
- Secondary treatment of all discharges from agglomerations of > 2000 p.e.,
and more advanced treatment for agglomerations >10 000 population equivalents in designated sensitive
areas and their catchments;
- A requirement for pre-authorisation of all discharges
of urban wastewater, of discharges from the food-processing
industry and of industrial discharges into urban wastewater
- Monitoring of the performance of treatment plants and
receiving waters; and
- Controls of sewage sludge disposal and re-use, and treated
waste water re-use whenever it is appropriate.
