Abstract

Among the management tools discussed in the Law 9.433/97, water charging is one of the most complex in the implementation process of the Water Resources Policy. One of the most difficulties for the valuation of water resources is the absence of a formal water markets. To support the valuation of water it is important to consider the principles of economic theory in order to consider subjective aspects, which are inherent to this theory, such as social and economical that will assess whether the price of water is within the users’ income range. This paper presents simulations of demands for human consumption water in order to evaluate the economical impact over the family income of the Community Salão, located in the rural zone of Serra Branca-PB municipality, in the region of the Paraíba River Watershed, Paraíba/Brazil. It was observed that the highest impacts are in the poorest family with and high number of residents, being mineral water the modality which provokes the higher impact. The final result supports the studies of economic valuation of water resources for the rural supply.
