Factibilidad de aprovechamiento de la fuente de agua del Río Pachijal para el abastecimiento de agua potable en la parroquia de Nanegalito - Chocó Andino : evaluación hidráulica

Abstract

This project proposes the design of a pipeline and its feasibility for the use of a water source from the Pachijal River for the supply of drinking water in the parish of Nanegalito. The community of Nanegalito is located northwest of Quito, the capital of Ecuador. This system is being developed to increase the consumption flow because the current supply is not sufficient and in dry seasons it is almost nil. The hydraulic evaluation of the water conduction line from the river catchment to the arrival tank was carried out based on technical visits, topographic survey where georeferenced points were taken of the possible catchment site, arrival tank, analysis of routes and alternatives for the conduction line route, in addition to this, flow gauging was carried out in the water body (supply source) and current storage tank. To obtain population data, information was sought on the website of the National Institute of Statistics and Census (INEC).

Theoretical flows and river flows were calculated with the data obtained from the gauging; in addition to the census information, the future population could be analyzed to establish whether the current flows are sufficient and to assess the need for a new supply source to increase the flow.

With the data obtained from the technical visits, different software such as Civil 3D, EpaCAD, EPANET, Plex Earth, Google Earth, were used for the construction of planimetries, water conduction profiles, valve placement and others. After this, the best alternative for the pipeline layout was selected, which is the third layout, to carry out hydraulic simulations and to know velocities, pressures, diameters, lengths and elevations of the project. After the simulations, a cost estimate was made for the pipeline so that the GAD Nanegalito can analyze the feasibility of proposing the definitive design project for the expansion of the current supply system.
