AVALIAÇÃO E READEQUAÇÃO DOS SISTEMAS DE CAPTAÇÃO E TRATAMENTO DE ÁGUA DO SAAE DO MUNICÍPIO DE MACHADO - MINAS GERAIS

Abstract

Due to the population and industrial growth of the county urban areas, the consumption water comes up with recording significant and variable rise along the days and the year. Against the functions of the responsible dealers to operate and maintain the public water supply systems with the quantity and quality, uninterrupted, the performance assessment is a management tool, in order to allow the identification of the devices, which need adjustments Since so, the present work has as general objective to evaluate the hydraulic performance of the main units of the water abstraction and treatment systems of the SAAE of the city of Machado, MG, for the consumption demand of the urban perimeter and the 20-year project period, as well as to size and implement the necessary adjustments for The units, which \present hydraulic incapacity in relation to the normative parameters. Therefore, through the researches and the results obtained, it was found that the Parshall measurer and the fast filters are the only units supply system that don´t need readjustments, because presents satisfactory performance, in agreement with dimensioning hydraulic parameters and pumping period defined. To the adduction units, pumping stations, flocculation and settling tanks should pass by readjustments to operate efficiently, so attending the consumer demand study. Due to the absence of a device to retain and sediment the solid materials (sand), a sandbox was designed in the catchment system.
