Modelo de calidad de agua de la red de distribución de agua potable de la ciudad de Riobamba. evaluación de la influencia de la instalación de cisternas y depósitos domiciliarios en la pérdida de calidad del agua. (Caso de estudio Red el Carmen).

Abstract

The main objective of this Project was to develop the hydraulic model and drinking water quality distributed through Riobamba city underground network, which allows an intermittent service that evidently affects water quality. The research was conducted in Carmen`s network that has a continuous service. Initially, the project consisted of obtaining information on diameters, lengths, consumptions, the material with which the network was skeletonized. In order to have a more accurate model, water samples and free chlorine analysis were taken in situ throughout the network, where free chlorine values were obtained that allowed us to perform the calibration and validation of the model, as well as free chlorine in homes, was analyzed. for seven days a week and at different times to determine the degradation of chlorine in tanks and tanks where free chlorine values were obtained that are outside the NTE INEN 1108 norm. The simulations of dwell time, pressure, speeds, flow, degradation of chlorine, reach of the water in the network in 24 hours, where we check deficiencies in the network mainly at times of lower consumption and at points furthest from the deposit where the chlorine degrades in the network due to certain conditions such as low pressures and long residence times. From this research it is concluded that while the water remains stored for more time in the network and in tanks and cisterns it suffers a degradation of chlorine, which depends in the same way on the pressure and the speed of the network, so the installation is recommended of chlorine reinjection points in the most distant points, a periodic cleaning of cisterns and tanks, and that a continuous service of potable water is guaranteed by the responsible entities.
