  ABSTRACT: Assessment of water and energy footprint for eight bottled water industries was carried out. The investigation showed that one litre of bottled water has a water footprint of 17.41 litres and energy footprint of 7.08 MJ. Water consumption by the industry comprises 61% during material production, 17% in processes, 16% in energy and only 6% in the actual product. Hence, maximum consumption of water is in material production, while the processes required a smaller fraction of the total water and energy consumed. Therefore, water footprint can be reduced through optimization of water consumption in material production.
