According to the ministry, the increased demand for water is particularly typical in touristic areas and in the part of the Budapest agglomeration where the population has grown dramatically in recent years.

In the Balaton area, on an average mid-year day, the amount of water used is 70,000 cubic meters; on a summer day, this increases to 90,000 cubic meters, and in times of persistent heat, it can be up to 130,000 cubic meters.
