In a biotech world, water networks are a bigger deal than bit streams. You’re not made out of digital bits – like all living things, you are made mostly of water. So that’s where you sensibly place your high tech investments.
Bruce Sterling

Our Bottom Line: During the next 10 years, many countries important to the United States will experience water problems – shortages, poor water quality, or floods -- that will risk instability and state failure, increase regional tensions, and distract them from working with the United States on important US policy objectives. Between now and 2040, fresh water availability will not keep up with demand absent more effective management of water resources. Water problems will hinder the ability of key countries to produce food and generate energy, posing a risk to global food markets and hobbling economic growth. As a result of demographic and economic development pressures, North Africa, the Middle East, and South Asia will face major challenges coping with water problems.

We consume
massive quantities of water
to generate energy,
and we consume
massive quantities of
energy to deliver clean
water.” Michael E. Weber,

Water Saving is Energy Saving
• Water not consumed saves energy• Water not transported saves energy• Water reused saves energy• Decentralized, ecological water treatment does all of
the above
Moving 1 billion gallons of water one mile consumes 16,500 megawatt hours,
= annual consumption of about 1,000 homes
