“Diseño del sistema de alcantarillado, tratamiento de aguas residuales y alternativas para tratamiento de agua cruda para la Comunidad de Chimborazo, parroquia San Juan, cantón Riobamba”

Abstract

This technical project is aimed at the design of the sewage system, wastewater treatment and raw water treatment alternative of the communities of Chimborazo and Santa Isabel, San Juan parish, Riobamba canton. The problem found is not having water suitable for human consumption, they also have saturated septic wells and mostly discharged directly into the river. For the raw water treatment alternative a disinfection system is required, which obeys the design parameters recommended in the TULAS and IEOS; for its part, the sewer system will be only sanitary as there are transverse rainwater collectors unloading into the Chimborazo and Pasguazo River; the geometric method estimates the future population, with a design period of 25 years for rural areas complying with the design parameters based on standards and technical specifications in force in the country, thus having optimal and efficient systems. Due to the topography, because there is no favorable slope there is a wastewater pumping system, on the other hand, the treatment plant consists of primary, secondary and tertiary processes, which depend on the design flow of the project, its final discharge has two alternatives: for irrigation or discharge to the river. In addition, the project provides for an environmental impact analysis that tells us the parameters of environmental mitigation during the implementation stages of the project. Finally, a reference budget is indicated that exposes all construction costs including a schedule of the work.
