Integração dos instrumentos outorga e cobrança pelo uso da água para a gestão das águas subterrâneas.

Abstract

The use of groundwater has become increasingly common, especially in coastal urban centers where the availability of this resource becomes more accessible. Thus, water resources management entities are concerned about mechanisms of implement control that can enforce the rational use of this feature. This assignment establishes criteria and simulations for water rights concession as well charges in the Sedimentary Basin of the coastal region of the Lower Course of Paraíba river basin, in Paraíba. In this research, criteria for water right concession are presented as the priority of use of surface water and water quality. Regarding the charging for the use of water, the criteria chosen were related to the class of environment, to seasonality, availability and type water users. For the simulations developed with a charging instrument a series of coefficients of seasonality and water availability collecting was used. The unit value of reference used was considered by deliberation Nº 01/08 of the Paraíba Water Basin Committee (CBH-PB). Simulation of price of the demands for the human supply of João Pessoa city are also presented and applied in two alternative use in water scarcity: periods water transported by car-kite; and use of mineral water. The results show the priceelasticity of the requirement in these alternatives.
