Diseño de un sistema adaptable de captación y aprovechamiento eficiente de agua lluvia para uso doméstico en Colombia

Abstract

Rainwater harvesting for domestic use in Colombia remains limited, despite the high availability of rainfall across much of the country, highlighting the need for complementary water supply alternatives in light of the challenges of sustainable water resource management. In response, an adaptable rainwater harvesting system for domestic use was designed, based on the determination of technical, environmental, and economic sizing variables and the formulation of four technical configurations tailored to different usage contexts (small homes, large homes, nurseries, and home gardens), whose efficiency was calculated under various climatic conditions representative of the country. As a result, a basic, adaptable model with an independent catchment area was developed, along with a guide to technological solutions that helps end users select the most appropriate system for their specific context. The project provides a technically sound and replicable tool to strengthen sustainable water resource management in Colombian domestic settings.
