Graphs for national stats

In 2016, Spain had 2084 urban waste water agglomerations of more then 2 000 population equivalent (p.e). These agglomerations generated a total load of 64 819 277 p.e. 98% 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 32 primary treatment plant, 619 secondary treatment plants and 1174 more stringent treatment plants. All these treatment plants have a total design capacity of 97 513 858 p.e.
