Resumen

Water is one of the most important elements, as it is essential for human health, environmental sustainability and economic prosperity, as water ensures the reproduction of all ecosystems and the dynamics of each population. Therefore, water scarcity is a problem that affects most of the world, whether due to climate change, indiscriminate exploitation of natural resources or pollution. Water is an urgent need in many areas, as they do not have enough liquid or do not have access to safe supplies, a problem to which the municipality of Rovira Tolima is not atypical, as it is not ensuring the availability of water and its management is not being sustainable, which is causing negative effects both on the health of its inhabitants and the economy of this population. Therefore, the scarcity of water in the municipality of Rovira affects domestic and commercial work, causing increases in products, because productions are diminished by the absence of water. There are also evacuations of its inhabitants, since the living conditions are not optimal and in addition to this, there is evidence of diseases that influence the health of the community as a result of the fact that the inhabitants are forced to consume contaminated water due to the lack of liquid. Therefore, the main objective of this project was to identify the intake site of the drinking water treatment plant in the municipality of Rovira, which will ensure that the flow meets the requirements and thus avoid shortages, in addition to maintaining the sustainability of existing ecosystems in the tributary and ensuring the environmental flow. For the definition of the catchment site, a methodology was carried out that contains five (5) stages, in the first one all the necessary data were collected for the accomplishment of the hydrological study and hydric balance of the hydrographic basin (river Luisa), which will supply the plant. These data were obtained through the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) and the Agustín Codazzi Geographic Institute (IGAC). In the second stage the collected data were analyzed and the information was completed to enter it into the implemented software (ArcGis ArcMap 10.3) being this the third stage and thus carry out the necessary studies. In the fourth stage the plans that contributed to the identification of the adduction point were exported and in the fifth stage the data processing and its due analysis were carried out, with which the location of the optimal point was reached.
