Evaluación de la red de alcantarillado existente y diseño de la red principal, emisario y planta de tratamiento del barrio San José de Tucuso en la parroquia de Machachi

Abstract

This project proposes the evaluation and redesign of the combined sewerage system, the implementation of a final outlet and the design of the wastewater treatment plant for the San José de Tucuso neighborhood, located in the Santiago de Machachi parish of the Mejía canton. One of the objectives is to make the sewerage system independent because it connects with the Machachi neighborhood system. Therefore, a treatment plant must be implemented which complies with sanitation regulations and thus guarantees a pollution-free discharge to the San Pedro River. The combined flow is 5,84 m3 / s which will go to a flow separator which will divert a flow of 48,45lt / s to the treatment plant and a flow of 5,79 m3 / s to the discharge. The flow separator will be a thin-walled side weir. The treatment plant will consist of a pre-treatment unit which will be an inlet channel with grids, a primary treatment which will be an Imhoff tank and the secondary treatment which will consist of a sludge drying bed. Due to the large slopes found in the discharge area and the lack of geomechanical information, two alternatives have been proposed in the perfectibility stage. Finally, a referential budget, plans of the sewerage network and the treatment plant are presented.
