Mejoramiento de la eficiencia operativa del sistema de aprovechamiento de agua lluvia en una vivienda urbana de la localidad de Suba en Bogotá

Abstract

The use of rainwater is a practice of efficient use and saving of water, which is of special interest considering the growth trend in the demand for drinking water in the country and the critical conditions generated by climate change that, for example, have to many regions of Colombia in rationing of this vital liquid. Rainwater is one of the most abundant and most wasted resources, especially in cities like Bogotá, where there is a cold humid climate and high level of precipitation. Rainwater use systems that begin with the collection or also called “harvesting” of rainwater, is a strategy that is presented as a sustainable solution for the replacement of drinking water in uses that do not require it; However, efficiency in the operation of these systems is essential to maximize the use of water resources. Therefore, in this research work, the improvement of the operational efficiency of the rainwater use system in an urban home in the town of Suba in Bogotá is proposed. The proposed methodology is to establish the reference line of the parameters and variables of the current operation of the rainwater use system (SCALL) in the home; identifying problems, deficiencies and failures that affect its proper functioning, and then proposing alternatives to improve the overall operational efficiency of said system. The main result achieved is the determination of the alternative with the greatest technical and economic feasibility for improving the overall operational efficiency of the SCALL of urban housing in the Suba sector in Bogotá, which consists of improving the use of stored rainwater (reserves) in the different levels or cascades of the system and in reducing or eliminating failure events in said system. The implementation of this alternative represents an improvement in the overall operational efficiency of the SCALL, which increases on average from 2% to 10.57%, with its respective economic savings due to the replacement of drinking water.
