Water footprint, conceptual image. Water flowing into a pair of jeans from a bottle, representing a water footprint (virtual water content). This is an ecological concept similar to that of a carbon footprint. It is a measure of the demand (in volume) that a product or service has on freshwater resources. It may also be applied to the person or population that consumes those goods and services. It is estimated that producing jeans takes approximately 10,000 litres of water (virtual water). This water footprint includes rain water, irrigation water, water used in producing the jeans and water polluted during the process.
