Water

Why are we concerned about water?

Globally, water will be one of the most scarce resources
- World Economic Forum reports that 44% of people currently live in areas that are “water stressed”
- By 2025, 4 billion people (half of the population) will live in sever water stress conditions
- Water demand tripled from 1950-2000
Poor water quality can lead to disease and illness
Energy is used to heat, cool, pump, filter, cleanse, treat, monitor and process water back to original or acceptable state
Costs involved to obtain water from utility company
Costs involved to dump back into sewer/drain system
Business risks from suppliers running out, or increased regulations, political unrest and scarcity

One major concern about water is how much we use. There are tools that can help companies and organizations reduce and conserve water, such as Water Gemba Walks, Water Balance Maps, and adding water usage to value stream maps (VSM).
