Looking to the Past
for the Future
To use water efficiently in space, we needed to understand how we use water today. To our utmost surprise, not a lot has changed in 5,000 years. Yes, our channels to access water have evolved, but how we use water has not- it still flows out of an output source and down the drain, uncaptured and unrecycled.
Even worse, we lose about 20% of piped water in pipeline leakages. Unknown to many, only 3% of the world’s water supply is accessible as freshwater, 2% of which is frozen in glaciers.
Worldwide, we are all experiencing a decline in water availability, with some countries suffering more than others.
