In 2018, Austria had 633 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 20 678 876 p.e. 99% of this load is connected to collecting systems and 1% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 3 secondary treatment plants and 630 more stringent treatment plants. All these treatment plants have a total design capacity of 21 579 063 p.e.
