Water-saving perlators (aerators), which were attached to the taps at the Corvinus in the summer, are able to reduce water consumption by 10-13 litres per minute. Instead of the previous 15-20 litres, the quantity of water flowing from the taps may be reduced to 5-7 litres, without deteriorating user comfort. The development was realised as part of the Corvinus Green project aimed at making the infrastructure of the University more sustainable.
Perlators mix air into the flow, so the water flowing from the tap becomes fizzier. You will notice no difference in water pressure and quantity, so quality is still at a high level. It is primarily the reduction of the quantity of water used for washing hands where this development helps. For the filling of water bottles, new water purifiers have been installed, so you can get good quality drinking water without plastic pollution.
Based on the average of the last three years, almost 25 thousand m3 water is consumed in the buildings of the Corvinus. Although it is generally considered that Hungary has huge fresh water stocks, the draught situation in this year made it clear that this is by no means true. That is why it is important to reduce water consumption in every-day life, too, and the first step could be the installation of water perlators.
Additional small steps include turning off the tap while rubbing soap on your hands, and not letting the water flow unnecessarily while washing the dishes. In the toilets of building E, please note that the taps are not turned off automatically, and the citizens of the University will soon be warned about this by posters. However, in building C, taps are turned off automatically, so you cannot influence their operation there.
The employees have also been asked to comment on the sustainability of the Corvinus. In the questionnaire related to the Corvinus Green project, respondents shared various ideas, such as reducing the volume of printing, more colourful biodiversity in the campus, selective waste collection, and optimising the efficiency of the water, electricity and air-conditioning technology. The Corvinus wishes to gradually incorporate these ideas in its operation, and the installation of the perlators was also part of this initiative.
The Corvinus University of Budapest is committed to support community sustainability activities and sustainable operation, as we need joint action to achieve significant changes.
