…is it possible to really measure what we spend?

Last March 5, 2024, with the Sustainability Office, we collected some data related to the water consumption of all the taps in the Faculty of Political Sciences and Sociology.
We observed whether there are noticeable differences between the different types of faucets in terms of the time it takes for an inch, and/or the pressure with which the water comes out.

The measurement is carried out in a very simple way, with a bag that collects the water that comes out of the tap with each inch, and a test tube with which we looked at how many mL, cL or L corresponded to the inch in question.

From the observations, we could say “homemade” that we made, we learned, however, that obtaining data on water consumption is not easy, even with the same brands and models of faucet!

Example of a table on which we have collected the data relating to the tap time and the water outlet pressure. We understand that pressure is easily uneven between taps because it is regulated manually, and millimeters make a difference. The most surprising thing has to do with the inch time, which depends on the manufacturer of the faucet. As in the example of toilet B3b/087 on the second floor of the Faculty, two identical faucets have different inch times.
