Defined water pollution

Water footprint and water pollution

How much water do we need?

you think 130 liters per day? That is the amount of water that runs out of the tap or the connections for washing machines, dishwashers, etc. in our households.

But what about the water that is used to manufacture all of our consumer goods and foods? If you take that into account, we need Austrians around 4,000 liters of water per person per day. That is ours Water footprint.

The water footprint of a person, community, or company is defined as that Total volume of fresh water used to produce the goods and services, that are produced by the individual or community, or by the company. The water consumption is measured based on the volume of water consumed (evaporated) and / or polluted per unit of time.

A water footprint can be for any well-defined group of consumers (e.g., an individual, family, village, city, province, state, or nation) or producers (e.g., a public organization, a private company or an economic sector).
