In 2018, Sweden had 422 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 12 616 780 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 0 secondary treatment plants and 432 more stringent treatment plants. All these treatment plants have a total design capacity of 13 860 977 p.e.
