Diseño del sistema de alcantarillado sanitario y planta de tratamiento de aguas residuales para los habitantes del caserío El Pingue, parroquia La Matriz, cantón Pelileo, provincia de Tungurahua

Abstract

Access to sanitary sewage systems is of vital importance to ensure optimal sanitation conditions and prevent negative impacts on both human health and the environment. In this context, the hamlet of Pingue faces limitations such as the absence of basic sanitation infrastructure, which directly affects the quality of life of its inhabitants. This project was developed in several essential phases, each one focused on fundamental technical aspects. In the initial phase, a topographic survey was carried out, and surveys were conducted to obtain information on the conditions of the community, as well as the needs of the population. Based on this data, we proceeded with the preliminary design of the sewerage network and treatment plant, applying the corresponding regulations, such as Bolivian Standard NB 688, CO 10.7 - 601 and CO 10.7 - 602 and Senagua guidelines. In the next phase, an economic evaluation was carried out, including the calculation of unit costs and the analysis of the financial viability of implementing the project. As a result of this project, a detailed design was prepared for the sanitary sewerage system, which includes 88 wells and 87 pipes, with a total length of 2,353 km. In addition, an existing network was analyzed, which consists of 57 wells and a length of the existing network of 1,299 km. Finally, technical calculations were developed for the wastewater treatment plant, where the processes were analyzed, including pretreatment, primary and secondary treatment. Ensuring that the total flow complies with the parameters required for proper operation. An economic study of the project was also carried out, with a budget of $345,842.12 and its respective specifications to guarantee the improvement of sanitary conditions.
