Evaluación hidráulica del sistema de alcantarillado combinado en el sector de la Universidad del Azuay

Abstract

This paper assesses the hydraulic performance of the combined sewerage network in the sector adjacent to the University of Azuay. The study is carried out on the basis of the main design parameters of a sewerage network. For the correct representation of the system, a numeric model is developed using the SWMM 5.1 program, which allows us to consider the variables necessary for the simulation of registered precipitation events and design storms for a specified return period. The efficiency of the sewerage network is analyzed based on the values allowed by the regulations. The results of the simulation of the events for the current condition of the system show an inefficient operation of the system with flooding in several sections of the main collector. Therefore, is adopted as a solution the alternative of increasing diameters and adding a lateral spillway designed by empirical methods. In this way the optimal performance of the network is achieved, and obtaining a basis on which future studies can be incorporated related to the nature of the river, the permeability of the land and the detailed design of the spillway.
