APLICAÇÃO DO PLUGIN SANIHUB (QGIS) NO DIMENSIONAMENTO DE REDES COLETORAS DE ESGOTO: ESTUDO DE CASO PARA A CIDADE DE ROCHEDO, MS.

Abstract

One of the main challenges for urban development and public health in Brazil is the universalization of basic sanitation. This study presents the development of the Basic Design for the Sanitary Sewage System for the consolidated urban area of Rochedo, MS, aiming to address the current lack of collection services. The methodological approach was based on the use of geotechnologies, employing QGIS software and the SANIHUB plugin for the automation of the network layout and hydraulic sizing, considering a 25-year project horizon. The geomorphological characterization of the region, marked by depressions, required the conception of a mixed system composed of gravitational collection and pumping. The results indicate the implementation of 24.9 km of collection network, predominantly in PVC DN 150 mm (99.8%). Complementarily, two Sewage Pumping Stations with submersible motor-pump sets were sized at a preliminary level, in compliance with ABNT NBR 12208/2020. The synthetic preliminary budget estimate, prepared based on SINAPI (Dec/2024), resulted in an implementation cost of R$ 1,855.21 per inhabitant. It is concluded that the proposed technical solution demonstrates conformity, constituting a fundamental basis for mitigating environmental liabilities and improving the quality of life in the municipality.
