In 2018, Slovakia had 356 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 4 168 420 p.e. 87% of this load is connected to collecting systems and 13% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 2 primary treatment plant, 82 secondary treatment plants and 182 more stringent treatment plants. All these treatment plants have a total design capacity of 6 321 636 p.e.
