In 2016, Portugal had 447 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 12 237 640 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 8 primary treatment plant, 271 secondary treatment plants and 193 more stringent treatment plants. All these treatment plants have a total design capacity of 16 766 307 p.e.
