Sistema para el Aprovechamiento de Agua Lluvia en Edificios de Mínimo Seis Niveles en la Ciudad de Bogotá D.C.

Abstract

This paper presents some models of rainwater collection systems for vertical structures in Bogotá city, greater than six-story as an alternative to give a much more efficient use to the pluvial resource, mainly in tasks that do not require the exclusive use of clean water. Some of the proposed uses are hand washing, washing of clothes and buildings front in some cases, the toilet, the washing of kitchen utensils, the irrigation of plants and green areas. In addition, the benefits of those models are shown as the reduction of the value in the aqueduct's invoice by the respective decrease of the consumption of clean water and consequently the domestic residual water in the sewer. Moreover, it is manifested that the system does not generate major changes or invasive in the structure of block of flats, the project has a return rate less than five years, and its useful life is greater than ten years among others. Bogotà, has a geographically strategic position which allows a rainfall regime above the average, guaranteeing service almost all year. The environmental, technical, financial and market studies are part of the main structure, which facilitates its sizing and specificity in the different characteristics and allows to establish that it is sustainable and profitable in the long and medium term, according to the type.
