Quality analysis of atmospheric reservoirs in networks with intermittent service
Main Article Content
Abstract
In Latin America, the installation of atmospheric reservoirs is frequent due to various policies related to water availability and management. This type of infrastructure, in addition to modifying the hydraulic behavior of the network, significantly alters the quality of the water, conditioning its microbiological characteristics and exposing the user to health problems. The hydraulic characterization of the reservoirs has been widely approached from the point of view of the way in which their filling/emptying cycles are reproduced, however, they have not taken into account several factors that modify the concentrations of disinfectant in the reservoirs, either promoting a post improvement or an impoverishment of this, in terms of quality. In the present work, the Epanet Toolkit model is applied to analyze the loss of water quality in the tanks as a function of the chlorine concentration conditions available in the main network and based on different intradomiciliary hydraulic peculiarities such as the change in the demand pattern, the variation of the regulation volume, the operation of the valve that controls the level in the cisterns, among others.
