Estudio de mejoramiento del sistema de alcantarillado sanitario existente de la cabecera del cantón Mocha, provincia de Tungurahua

Abstract

This technical project presents the deficiencies of the sanitary sewerage network in the winter season, thus causing a premature delay of the inspection wells. In this project, the evaluation of the current sanitary sewer system was carried out through technical sheets that assess the measurements, operation and physical state of the wells. For the redesign, a topographical survey was carried out with RTK precision equipment; With the data obtained, the hydraulic evaluation of the existing system was carried out. Given that most of the sanitation system does not meet the minimum hydraulic parameters, it was decided to carry out a redesign of the aforementioned system. To carry it out, it was necessary to use as much as possible the same garments from the wells to have a more viable proposal. In addition, the treatment plant that receives the flow from the sanitation system under study was evaluated. To carry out this process, a volumetric evaluation was changed to verify if the purification units are supplied to the estimated future flow. As a result of this project, two main branches were obtained, the design consisted of 12.8 kilometers in which 257 inspection wells with heights ranging between 1.20 m and 5.0 m were required. With reference to the treatment plant, some improvements will be made in the units such as: sludge drying bed, biological filter. Additionally, a chlorination booth was integrated into the purification process to reduce environmental impact.
