Water pricing and household water use in Spain and Estonia
As of and including 2007, the survey questionnaire explicitly asks for the value of the sewage tax, which by delegation is billed by municipal councils and water cycle management bodies. This leads to a better estimate of the expenditure on waste water purification, which must be taken into account when comparing water unit cost indicators with previous years.
