In 2016, Bulgaria had 328 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 7 448 278 p.e. 86% of this load is connected to collecting systems and 8% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 2 primary treatment plant, 9 secondary treatment plants and 97 more stringent treatment plants. All these treatment plants have a total design capacity of 8 536 001 p.e.
