The undertaking reports total water withdrawal into its boundaries; if its production processes use water significantly (drying, power generation, manufacturing, irrigation and the like) it also reports water consumption, being withdrawal minus discharge from those processes, and separately the water consumed at sites in water-stressed areas. Micro reporters with a staff of ten or below may skip this datapoint.
