Abstract

With the rapid and disorderly growth that occurred in the city of Caxias do Sul - RS in the last two decades, many problems of water supply are observed in specific areas, especially in peak times and days of consumption. In order to solve the mentioned problem and focusing on energy efficiency, this study proposed two improvements in the pumping system of Santa Fe, which is responsible for supplying the northern part of Caxias do Sul. The improvements mentioned dealt with the exchange of the pumping system and the use of a frequency converter to control its speed. From the measurements made and simulations in spreadsheets and software Epanet, it was found that the two improvements are technically and economically viable, providing an estimated monthly savings of 37.7%.
