ABSTRACT
To achieve optimal rationality and efficient freshwater use, the latest Brazilian methods for charging payments based on water withdrawal generates a criteria of good practices in water use. The São Francisco River Basin (SFRB), mainly located in the Brazilian semi-arid area, included such parameters in 2019 modifying 2010 procedures. This study comparatively evaluates these procedural changes, taking the water distribution user sector as the subject of the investigation. Results indicate that the measurement parameters, which adjusted priced water volume, stimulated an overestimated water license to receive a 24% payment bonus. Furthermore, the inclusion of a water loss index is based on weak parameters, which allow up to 50% of water loss without penalty. In the three water systems observed, the cumulative effect of the measurement and water loss criteria imply a reduction of almost 40% water charges since 2019. Thus, the procedures adopted in the SFRB, a region with structural water scarcity, are not consistent with their initial objective of rational and efficient water use.
