In 2016, Luxembourg had 48 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 637 438 p.e. 99% of this load is connected to collecting systems and 1% addressed through Individual and Appropriate Systems (storage or septic tanks, micro-stations,...). These agglomerations are connected to 14 secondary treatment plants and 17 more stringent treatment plants. All these treatment plants have a total design capacity of 874 500 p.e.
