Thus, in the agrarian sector, information is collected regarding the availability of water, according to the origin thereof (surface, groundwater, other resources) and regarding its use in plots, by crop group and irrigation technique;  in the manufacturing industry sector, the objective is to investigate the volume of water input used, and of water disposed of, as well as the average price for the supply and sanitation of the water. In the services sector, the use of water is investigated  to enable the development of indicators that establish the average  water use endowments in relation to the final consumers thereof.
