Article 5(2) applied: 
When this Article of the urban waste water treatment directive 91/271/EC applies, Member States shall ensure that urban waste water entering collecting systems shall before discharge into this sensitive areas be subject to more stringent treatment for all discharges from agglomerations of more than 10 000 population equivalent. The starting date of application is the deadline that each agglomeration has to respect in this sensitive area.
