Abstract
During the 1990s, Colombia –and particularly, the city of Bogotá– underwent some changes in the models of water resource management. This paper provides a calculation of the water footprint in Bogotá in order to evaluate how the changes in the water management models impacted the water consumption and the wastewater discharges in the city of Bogotá. As a result, it was found that between 1993 and 2008 the city managed to decrease the consumption numbers in 40%, despite the gradual city growth and thanks to the fact that the pressure on the water resources decreased due to the administrative, legislative, and cultural changes implemented in Bogotá during the abovementioned time. However, the issue of wastewater discharge treatment showed to be a critical link, as the gray water footprint represents 55.8% of the total water footprint in the city. The wastewater discharges poured into the Tunjuelito River catchment area are the higher pollutant.
