Notes:
1) Up to the year 2006 (included), the questionnaire of the Survey on Water Supply and   Treatment: 
  
 -The variable 'Total volume of water registered and distributed   by type of user' was asked as 'total water volume   controlled and supplied to users'.   
  
 -The variabe 'Real losses' was asked in the questionnaire with the literal 'Water  volume losses in the distribution network (leaks,breakdowns, ...)'. 
  
 -The variable 'Apparent losses' was  not asked in the survey questionnaire. 
  
 -The variable 'water volume  supplied to the public supply network' was not asked in  the questionnaire. Its estimation was made summing the  variables: 'total water volume controlled and supplied to  users' and 'Water volume losses in the distribution network  (leaks, breakdowns, ...)'. 
  
 This methodological changes must be taken into account when comparing  data and indicators of the 2000-2006 series with  the infomation from 2007 onwards.
