Sustainable Water | The water footprint of an average American

According to a recent study by the Water Footprint Network (1), the “water footprint” of the average American is 32,911 glasses per day. 

This corresponds to 2,842 m3 of water per year [in the period 1996-2005]. The water footprint (WF) of the global average consumer was 1,385 m3∕y, whereas the average citizens in China and India have WFs of 1,071 and 1,089 m3∕y, respectively, less than half of the average American. Consumption of cereal products gives the largest contribution to the WF (27%), followed by meat (22%) and milk pro- ducts (7%).

Where does all this water come from? It’s used to produce the food we eat, clothes we wear and more.
