Mejoramiento del sistema de distribución de agua potable de la cabecera parroquial de san francisco del cantón Tisaleo provincia de Tungurahua

Abstract

Currently, the distribution system in San Francisco parish does not provide quality service even though it is practically new. On the other hand, the distribution system does not completely cover the parish, causing the inhabitants to look for other sources of supply. The present project has been carried out to improve and expand the system. Initially, the study area was delimited by means of the canton's cadastre, then a topographic survey was carried out with the help of an RTK. With the georeferenced plans of the existing potable water system, the system was evaluated and it was found that the storage tank of the study parish had a conduction network that fed the tank of the San Luis parish, so this parish was also analyzed. An evaluation was made both physically and hydraulically where deficiencies were found. Then, the existing system was modeled for scenarios in static and dynamic state, resulting that the two parishes presented problems of velocities and pressures. In the proposal to improve the existing system and expand it, two pressure regulating valves were installed in San Francisco parish and three pressure regulating valves were installed in San Luis three pressure regulating valves were installed, which optimized the pressures to 100 percent. The velocities in the two sectors were not optimized to 100 percent, so it was suggested that bleed valves be installed. Finally, a budget and schedule were prepared.
