In 2018, Poland had 1553 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 38 457 797 p.e. 94% of this load is connected to collecting systems and 5% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 56 primary treatment plant, 1024 secondary treatment plants and 612 more stringent treatment plants. All these treatment plants have a total design capacity of 52 583 551 p.e.
