Viabilidade operacional de modelos de cobrança pelo uso da água bruta para a Região do Alto Curso do Rio Piranhas.

Abstract

The water use Collection has been implemented very slowly in most Brazilian water parting, even though it was supported by Law No. 9,433 / 97, which established the National Water Resources Policy (PNRH) and created the National Water Resources Management System. Water Resources (SINGREH). So that the Piancó-Piranhas-Açu Hydrographic basin is not yet collected, so this study proposes to analyze which existing collection model (s) for the use of raw water can be Adopted in the high region of the Piranhas river? Initially a survey of the water grants issued in the study region was made through the website of the Executive Agency for Water Management of the state of Paraíba, and a diagnosis of the grants issued was drawn up, identifying the sources of collection. Then the models adopted in the state of Ceará were analyzed; In the Paraíba do Sul basin; In the Piracicaba, Capivari and Jundiaí rivers basin; In the São Francisco river as well as the one proposed for the state of Paraíba. Finally, through a technical visit to the thirst of the Regional Management of the AESA Hydrographic Basin III, in the city of Sousa, half structured interview was conducted with the responsible manager about possible information for the implementation of the charge for the use of raw water. Through the diagnosis of grants, one can perceive the real situation of water users in this region, evidencing the importance of efficiency in granting concession. Some models were implemented in a satisfactory way so that the methodologies are consolidated and accepted until the present day. The model proposed by the state of Paraíba, despite being the only one of the five studied, with capacity for the simulation due to the available data, can not be used in the Piancó-Piranhas-Açu river basin because it is a federal domain basin, Even so, simulating this model, the annual collection would be R$ 201,156.94; Considering a total of 213 users granted. However, the study did not critically examine whether the possible values could actually meet the basin's need if resources were sufficient for its recovery as well as environmental education practices.
