ABSTRACT
The present paper offers an analysis of the volumes of water implicated in the three subsystems of the Italian water supply system for the private sector: withdrawals, adduction, and distribution. The purpose is to propose a methodology for assessing the physical availability of water resources in Italy and the effects produced by the consumption levels for those resources within various hydrogeohydrogeological and management contexts.The information analysed in this document was drawn from the “Urban Water Census”, a survey that is periodically conducted by the Italian National Institute of Statistics (Istat) in order to analyse the water supply framework for private use in Italy. This survey is the only official and systematic source of data for the sector. The reference year of the data analysed is 2008, the most recent year for which census data is available. The frequency of these kind of census is not costant, but in the last twenty years it has been of about five years. So the methodology analysis, proposed in this paper will be applied to the next census data, which will be collected on next year.
