In 2018, Belgium had 379 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 9 206 300 p.e. 100% of this load is connected to collecting systems and 0% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 60 secondary treatment plants and 339 more stringent treatment plants. All these treatment plants have a total design capacity of 10 569 711 p.e.
