In 2018, Netherlands had 309 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 19 712 887 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 1 secondary treatment plants and 318 more stringent treatment plants. All these treatment plants have a total design capacity of 21 602 482 p.e.
