Diseño de un sistema de captación, almacenamiento y readecuación de las aguas pluviales para el Hotel Alejandría Resort, en el municipio de San Gil, Santander

Abstract

Rainwater harvesting systems (RHS) are used as a sustainable alternative to improve the water balance, the water footprint and reduce the economic costs associated with the expenditure of the liquid in the system. This document presents the design of RHS on the Alejandría Resort hotel, placed on San Gil, Santander, to supply the drinking water deficit. For it, the methodology of the Centro Panamericano de Ingeniería Sanitaria CEPIS was used, which implements three work fronts: the calculation of useful catchment areas, calculation of the supply of rainwater and the dimensioning of volumetric storage units. Additionally, a physicochemical and microbiological characterization was carried out using standardized methods for water analysis in order to calculate the risk index associated with RWQ water quality. The results suggest that the efficiency of the RHS will depend directly on the potential catchment areas, the rain supply and the storage capacity at the collection site, in addition, the characterization of the properties point to the need for an appropriate treatment to consider it safe for human consumption in compliance with resolution 2115 of 2007 of the Ministry of Environment and Sustainable Development.
