Análise econômica de sistema de abastecimento de água público fechado: estudo de caso da Cidade Universitária Professor José da Silveira Netto - Belém (PA)

Abstract

The water supply is of paramount importance not only for human survival, but also for the development of economic activities and institutional, that is, to organic life / biotic and social life. Regarding the availability of this feature Brazil is a country with huge potential reserves to meet this end. The City University Professor José da Silveira Netto, the UFPA campus, currently produces its water, with funding through an underground aquifer, and in small quantities, also purchased from Local Dealership. However, in relation to production at the Federal University of Pará there is no knowledge about the maintenance costs of the production line, the hand labor involved, etc.. The lack of such knowledge does not allow the manager to act strategically with respect to this situation. This work aims to raise the direct and indirect costs of production of 1m³ of water treated at the City University Professor José da Silveira Netto, comparing it with the amounts charged by the Concessionaire site in order to show the manager what the most advantageous to the Administration with relation to the matter being addressed. Furthermore, future scenarios have been created in order that the activity is dynamic and growing university, beyond what was incorporated as conditions of energy cost and value of grants for water use, not yet integrated into the current cost of production. The results clearly demonstrate that the option of producing drinking water is the most economically advantageous for the institution, in any proposed scenario. Noting that the cost per m³ of produced water ranges from R$ 0,31 to R$ 0,45, while the purchase through the Local Dealership, around R$ 4,30 / m³ for the year 2011, only show viable if that price is a maximum of R$ 0,50 / m³. With this information and analyzes adequately presented clearly and technically considered, this work may be used as a management tool that will permit the public better or more adequate system of water supply in the City University Professor José da Silveira Netto.
