Estudio de prefactibilidad para el sistema de conducción y tratamiento de agua cruda en la Comuna Quinticusig – cantón Sigchos

Abstract

The technical project intends to carry out a pre-feasibility study for the raw water supply and treatment system to meet the demand for drinking water in the Quinticusig commune, Sigchos parish, Sigchos canton at any time of the year for 24 hours a day. The commune built a system to transport raw water approximately 35 years ago, it did not have technical assistance; the population suffers from a shortage of water for periods of more than 30 days, in summer, while in winter there is a waste of water resources. Scientific research was used, which uses theoretical and practical tools allowing a better visualization of the environment and identifying the current problems in order to determine a solution. The proposed conduction system has: catchment, adduction line, semi-buried horizontal sand trap and buried storage tank up to the crown of the walls, the complementary structures of the system are: an overhead crossing and five pressure break chambers. The treatment used in the water has a physical phase that takes place through the sandblasting unit, a chemical phase that consists of chlorine disinfection, carried out in the storage tank. The technical-economic analysis contains the detailed budget and the economic indicators (NPV, IRR, B / C), the results obtained reveal that the project is viable. Finally, in the environmental impact study it was concluded that the project does not have significant negative effects during the execution, operation and maintenance phases.
