Concepção e dimensionamento de rede de abastecimento de água do município de Japi-Rn: comparação de modelos computacionais de otimização

Abstract

Although very important for several sectors of a community, access to water is not always assured with sufficient quality and quantity for the population, since the construction of a water supply network is usually a very expensive project. This aspect is taken into a special relevance when these costs must be met by the income of a small municipality. This fact evidences the need for some localities to have access to a planned supply system and focused on the lower cost of implantation and operation. Thus, the present work aims to develop an economic design, based on the lowest cost, for the city of Japi, located in the Federative Unit of Rio Grande do Norte, by modeling and comparing the results of two optimization software supply networks. Initially, the current characterization of the locality was carried out in order to obtain the current project and the end of the project reach period data, with the objective of accomplishing an adequate design for the network. After that, the network modeling was carried out in the EPANET / LENHSNET and UFC programs (UFC-2 and UFC-4 modules), the sizing and comparison of results, network costs and design options were observed for each one as well. In spite of this, it was noticed that the UFC System has more options of dimensioning, such as the ability to define the unit head loss in the pipes and the possibility of evaluating the maximum static pressure, in addition to having a less expensive network.
