The main objective of the statistics on water supply and sewerage is to quantify in physical units and and value in economic magnitudes the activities relating to the so-called integral water cycle, comprising water supply and treatment (sewerage system and filtering of waste water).
Moreover, they provide information necessary for drafting water satellite accounts and meets the demand for this type of data by different users (national and international bodies, companies in the sector and public administrations).
The obtained information is integrated with data provided by INE company economic surveys (industrial and services) in order to gain a fuller picture of the water situation in our economy. Synthesis indicators are also drafted enabling interpretation of results obtained from users.
