“Evaluación y repotenciación del sistema de agua potable en la parroquia de Juan Montalvo cantón Cayambe”

Abstract

The Juan Montalvo parish is one of the eight parishes that make up the Cayambe canton, the main problems it suffers are: Water scarcity during the dry season, water contamination in times of heavy rains due to the transport of sediment from the sources where the water is collected for its use, in addition to these problems, iron content has been detected in the catchment springs which has come to clog the pipes, therefore, this project aims to propose and design an alternative catchment system and pipeline of the Juan Montalvo parish of Cayambe canton, To this end, a diagnosis was made of the existing catchments, pipelines and pressure chambers of the drinking water system, for which two alternative solutions were proposed, selecting one of them based on the technical, economic, environmental and social aspects, which consists of the design of a new catchment and pipeline system for the Juan Montalvo parish in the Cayambe canton; This consists of the design of bottom or Caucasian grate type catchments, a 4-inch PVC pipeline with a working pressure of 1.25 MPa, due to the high topographic slopes, it was necessary to place 6 pressure chambers to prevent damage to the pipeline due to overpressure; in addition, a sand trap tank was redesigned, which is where the pipeline network reaches, from where the water is taken to the treatment plant for final consumption. The total cost of the project is US$154,479.79. The project is economically viable with a B/C ratio of 3.78 and an IRR of 77%, its environmental impact is low and the social benefit is high. In addition, general and detailed plans were prepared ready for construction.
