In 2016, Lithuania had 65 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 2 905 700 p.e. 97% of this load is connected to collecting systems and 3% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 10 secondary treatment plants and 55 more stringent treatment plants. All these treatment plants have a total design capacity of 3 548 814 p.e.
