Total water consumption at the University of Barcelona has decreased by 76% between 1995 and 2019, with two particularly significant reductions:

  1. 24% between 2006 and 2008 as a result of the savings measures implemented and the greater degree of awareness in the use of water during the drought period that took place in Catalonia in 2007 and the first months of 2008.
  2. 45% between 2013 and 2018, thanks to greater control and monitoring of the consumption of each building, from the Maintenance Unit, which allows to detect leaks in facilities more quickly, and the implementation of various actions to restrict the consumption of irrigation water or in cooling towers.

We cannot ignore, however, the gradual increase in consumption experienced from 2008 to 2010, when the austerity measures implemented during the drought relaxed.

The reduction in 2020, 37% less than the previous year, reflects the closure of activity for a few weeks due to the covid-19 pandemic.

In relation to the geographical environment, the UB is following a trend similar to that of all the municipalities in the Barcelona Metropolitan Region, and since 2014 it has been more efficient than Barcelona City Council in consuming water for municipal services.
