“Diseño de una red de agua potable de 1,5KM para la junta de aguas, San Vicente de Andoas, cantón Pedro Vicente Maldonado, provincia de Pichincha."

Abstract

A drinking water network was designed for the water board of San Vicente de Andoas, Pedro Vicente Maldonado Canton, Pichincha Province, previously carrying out a georeferenced topographic study and redesigning the trajectory of the supply line to prevent it from interfering in future buildings. With a flow sampling in the old water supply line, resulting in an average flow of 0.00378 m3 / s, this value was taken as a reference to define the design flow of 0.005 m3 / s and a diameter of 75 mm, where a loss was obtained in the discharge line of 118.16 m. To overcome the losses generated in the discharge line, a 20 HP multistage pump with a manometric height of 120 m was selected, using the chosen pump an operating point of 0.00576 m3 / s was obtained, this data was obtained by simulating the hydraulic system with specialized software thus guaranteeing the technical viability of the project. Through the economic analysis, a value of $ 41,432 USD is estimated for the execution of this project, with an internal rate of return (TIR) of 9.47 %, thus being profitable.
