Caracterización del estado actual de los ríos Chiguilpe y Lelia como fuentes para los procesos de potabilización; y, del río Otongo como futura fuente para dotar del servicio de agua potable a Santo Domingo, provincia Santo Domingo de los Tsachilas

Abstract

Abstract:Ecuador is some country rich in water resources, according to the National Council of Water Resources (CNRH, 2002, 2006 a, 2006 b). According to this statement, it has been made the study "Characterization of the current status of the Chiguilpe and Lelia rivers as sources for the purification processes, and of the Otongo river as a future source for the potable water service to the city of Santo Domingo, province Santo Domingo de los Tsachilas", whose objective is to update the data on water supply and water quality, as well as to diagnose the current state of these watersheds and deliver a proposal for environmental management based on sustainability parameters. To estimate the flow of the Chiguilpe, Lelia and Otongo rivers, the float method was used (INEN 478, 2014-01) and to determine the water quality of the sources under study, laboratory analyzes were carried out, taking samples (INEN: 2169, 2013) at each gauging point. The diagnosis and characterization was based on studies carried out by the Municipal GAD and EPMAPA-SD, such as PDOT, Drinking Water Master Plan, (HANSOL, 2013), among others. The characterization of the basins of the Lelia, Chiguilpe and Otongo rivers shows that over time, the forest area has decreased and the agricultural frontier has expanded, and that the flow has decreased over time and due to erosion there are growing older. The environmental proposal has as a priority the reforestation and respect of the riverbanks.
