Figure 2. Flow Diagram for <strong>Zaragoza</strong> UWS. Lines and numbers in blue stand for water flows (units are<br />
million m 3 per year). Chemical products as well as sludge flows are represented by lines and numbers in<br />
green (units are thousand tons per year). Data used for this diagram are from the year 2006.<br />
* Values that have not been measured but estimated<br />
** Storm water overflows were estimated for the period 2001 – 2006 and are completely different<br />
between years. Therefore an average value is not given, but rather a range.<br />
*** 90% <strong>of</strong> water use is assumed to go to the wastewater system<br />
? Indicates balances that could not be completed due to information gaps<br />
Values that have been actually measured are not given any mark in this figure<br />
