Where is Earth's Fresh Water Stored?



The Stephens Glacier - From USGS: Glaciers hold about two thirds of all the world's fresh water
Most people know that most of the Earth's water is salt water in the oceans (almost 97% in fact).  Many people assume that fresh water is mostly found in rivers and lakes.  This is not the case.  Two thirds of all fresh water is in glaciers and ice, not readily accessible for human use.  As we see many glaciers in the northern hemisphere recede (even while they may be getting thicker in Antarctica), some of this ice may become available in fresh water lakes, but right now it is largely inaccessible.

Of all fresh water, 0.26% (or one quarter of one percent) are in fresh water lakes.  Over eighty percent of  all the fresh water in North American Lakes is in the Great Lakes region. (Incidentally, these lakes were formed by glacial melt after the last ice age, so glacial melt today could potentially have similar effects).. So, there is not much available to the Western part of the United States that most needs the water for irrigation and other uses.

What about rivers?  Well, all the rivers in the world only hold 0.006% (that is six hundredths of one percent) of all water.  We frequently use rivers to irrigate crops, but their main advantage is that they are self refilling, not that they hold significant water.  If fact, we use so much of the water from the Colorado river that it doesn't even reach the sea anymore.

With drought becoming more prevalent, and ground aquifers becoming depleted, isn't there another renewable source of water that could be tapped to grow plants?  Yes, there is.  0.04% of all fresh water is held by the atmosphere.  This is over six times what is available in rivers.  The problem, up until now, has been there was no effective way to harvest and store this water for use by growing plants.  The Groasis Waterboxx has changed all of that.

The Groasis Waterboxx is a self refilling water battery, an ingeniously designed dew harvesting device that pulls moisture from the air at night, and stores it to slowly distribute to the roots of a growing plant.  It also captures rainfall and stores this for later use.  See how the Waterboxx works in the video below:


The Groasis Waterboxx pulls water from the air, funnels it to a reservoir using its unique lotus leaf inspired lid,  and slowly distributes it to the soil beneath.  This allows the tree roots to grow to deeper capillary water (also called soil moisture, where another 0.05% of all fresh water is stored), making them drought resistant once the Waterboxx is removed and reused.  See the root growth with the Groasis Waterboxx at this link.  Contrast this to what is normally done when planting a young tree - drip or sprinkler irrigation means water stays in the top of the root zone, causing the roots to grow more shallowly and making them more likely to dry out during drought.  The Groasis Waterboxx has suddenly made this atmospheric fresh water, squeezed out in condensation most mornings, available for the growth of the plant.

We at Dew Harvest® LLC have used the Waterboxx to grow cherry, pear, oak, and sequoia trees, as well as annuals like pumpkins and cantaloupe.  Be the first in your area to begin planting trees the way nature intended with the Groasis Waterboxx.  Buy the Waterboxx today.
