The water is one essential to guarantee the life quality, is a factor that restrict the economic and social development in many regions. Despite of Brazil have a privileged situation because of the disponibility of the water, the geographical variability and the growth population have caused conflicts of use behind the sectors that use. From this perspective, one should highlight those economic activities whose uses of water resources are more intensive, like the industrial sector. To estimate water use in this sector there are several methods, though, the most part of this methods are based on data reported and compiled in the seventies in the United States reflecting, outdated technology and environmental of the production process, besides, this do not represent the Brazilian local conditions. Noting that technological developments of the recent decades has altered the use of natural resources in the production processes; there is a need for a more comprehensive, updated and specific study in Brazil, providing subsidies to companies and governing agencies for an appropriate planning and management program of water resources in the industrial sector. Thus, considering the importance of this matter and of the technical coefficients in the use of the water, this study aimed the construction of technical coefficients of water resources for the industrial sector in Brazil. To be successful in the objective, firstly was done exploration of dada of withdraw, of generation of effluents and consume by product (m3/produced unit), the dada of water flow and production, that allow prepare the coefficients. After this phase, the structure of the dada bank was composed and filled. The structure consider fields refer to name of the company, type, coefficients of capitation, consume and generation of effluents, allowing classify the information regarding many criteria. To classification of the type of the industries was considered the National Classification of Economic Activities (CNAE), version 2.0. After the cadastre of the information in the dada bank, were analyzed the difference of the dada in the same segment, trying explain this differences. The last phase was the validation of the coefficients, with discussion with public agencies, private institutions and others relevant entities of the industrial sector, aim to finish the dada and add pertinent contributions. The dada obtained in the research summarize 148 companies or associations, representing 51 types of economics activities. After the analyses and comparison of the results of the group of technical coefficients with dada of others methodologies, based in international dada, verify that the adoption of such values overestimates the coefficient of withdraw, consume and effluent associated with the Brazilian companies. It was realized that the dada presented by Integrated Pollution Prevention and Control (IPPC, 2009), comparing with other fonts, are the more indicated to represent the reality of the Brazilian industrial sector, when there isn t specific dada of the national industries. It is concluded that the CNAE allow define in a clear way as type associated with the main economics activities of the Brazilian industrial sector. The group of technical coefficient of water resources obtained in the present study reflects, in a consistent and correct way, the present situation of the Brazilian industries studies providing subsidies to companies and governing agencies for an appropriate planning and management program, controlling the rational use of water resources in the industrial sector brazilian.
