The treatment of urban waste water is fundamental to ensuring public health and environmental protection. Urban waste water treatment in all parts of Europe has improved over the last 30-40 years.

In 2017, most European countries collected and treated sewage to tertiary level from most of their population. In EU-27 countries (EEA 2020), 69 % of the population were connected to tertiary level treatment and 13 % to secondary level treatment.

Countries where less than 80 % of the population were connected to public urban waste water treatment systems were Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Ireland, Italy, Lithuania, Poland, Romania, Serbia, Slovakia and Slovenia.
