Cálculo de la huella hídrica de una lavandería industrial ubicada en el Área Metropolitana de Bucaramanga, Santander.

Abstract

This environmental engineering degree work evaluates the calculation of the Water Footprint of the Case Study located in the municipality of Santander. For the calculation of the Water Footprint, the methodology proposed by the organization Water Footprint Network was adopted, using equations that relate the consumption of drinking water, the production of waste water, the concentration of physicochemical parameters of the effluent and the natural receptor of the body of water, maximum limit value allowed by the norm and meteorological data, stories such as reduction and evapotranspiration, to finally obtain the general Water Footprint. The Water Footprint obtained a correspondence of 145,518 m3 / day for the year 2019, equivalent to the daily consumption of 1,119 Floridians. The Blue Water Footprint represented about 58.497% of the value of the total water footprint, followed by the Gray Water Footprint with 28.465% and finally, the Green Water Footprint with 13.008%. To reduce the Blue Water Footprint within the framework of the fulfillment of the Sustainable Development Goals, the use of rainwater was proposed, for this the storage volume is calculated, the tank was dimensioned, the conduction and the parameters of water quality, a financial analysis was also carried out indicating that in the optimistic scenario the proposal would represent the same savings as the use of the deep well
