Studies show that a combination of rising industrial water usage and population growth will result in a “water gap” between usable supply availability and demand of an astonishing 60% by 2030. This calls for drastic changes to water management processes, including the introduction of water recycling to business as usual activities. This will allow the safe reuse of process water, a reduction in water intake and the avoidance of contaminated wastewater polluting raw water sources.

2 Total increase capital of raw water through infrastructure buildout, excluding unsustainable extraction
3 Supply shown at 90% reliability and includes infrastructure investments scheduled and funded through 2010. Current 90% reliable supply does not meet average demand
