In 2016, Romania had 1870 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 20 142 050 p.e. 62% 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 41 primary treatment plant, 298 secondary treatment plants and 225 more stringent treatment plants. All these treatment plants have a total design capacity of 19 790 094 p.e.
