Simulação da cobrança pelo uso da água subterrânea

Abstract

The search for groundwater for different uses has been increasing especially in urban centers, highlighting the need for an efficient and sustainable management. The charge for the use of water, established by Law 9.433/97, is an important management tool, which aims at providing economic value to water and in doing so, stimulate the rational use and generate financial resources for investment in the recovery and preservation of the watershed. Therefore, this study has as a main objective the simulation of charging for the use of groundwater, according to the collection of taxes and economic perspectives in Maceió/AL-Brazil, based on the identification of users, criteria selection for charging, simulation of collection potential, impact assessment and acceptability of charging. In order to achieve this objective, the research broached existing laws related to the topic, national and international experiences of charging for the use of water and the main methods of price fixing. The basin studied was Reginaldo stream basin, which is completely inserted in the urban area of the city of Maceió, with an area of 26.86 square kilometers. The results showed that the application of different methods for setting prices for the collection of groundwater in the studied area presented quite different values. The different simulations indicated that the charging in Reginaldo stream basin is feasible from a financial perspective. In general, most interviewees are willing to pay to have water continuously and good for several uses.
