RESUMO:

The objective of this work is to propose a model to evaluate the water supply system of the Potiguar municipalities, which are served by the Companhia de Águas e Esgotos do Rio Grande do Norte (CAERN), in the operational management of water resources in drought years (2010-2015) by means of a dynamic modeling. The scenario of unsustainability observed in water reserves is a result of the lack of awareness and unrestrained use of water resources. Population growth and climate change further aggravate this scenario. The negative effects of the lack of water are present throughout the national territory, especially in the semi-arid region, where the impacts are observed more sharply. Thus, the Dynamic Data Envelopment Analysis model will be used to evaluate the context presented during a 5 year time window. The sample includes 155 municipalities from all mesoregions of the state. The modeling adopted considers 1 input variable, 2 output variables and 1 carry-over to represent reality. The data needed to conduct this work were obtained through consultations with the National Information System on Sanitation. At the end of the work, it was possible to observe that the supply systems studied operate, for the most part, inefficiently. Only 6% of the municipalities obtained maximum scores in the overall analysis. Although the performance of the mesoregions is also not satisfactory, the municipalities of the central meso-region have obtained better results, especially in 2013. Finally, it was possible to verify the negative potential of water losses and how this variable compromises the sustainability of the current system of supply of the cities of the State.
