Rain falling on flat fields has very little impact in refilling aquifers. In Texas for example, an acre of farmland receives 2-acre foot of rain per year, averaging less than 1/2" with each rainstorm. And unfortunately, most of this rain is quickly absorbed by the top couple feet of soil and is evaporated by the sun before it has an opportunity to travel deeper.
Water for Earth is going to change this.
The patented EM Locator Technology system identifies aquifers down to 5,000 feet within minutes. It's currently being used in Texas by Well Water Finders™ to find aquifers for water wells so water can be extracted from the ground to support livestock, farms, businesses and residences. Water for Earth will use this system in a different way - identifying entry points that can be used to refill aquifers so water can be put back into the ground. The technology can map groundwater levels that are present beneath the surface and also hard layers capable of forming artificial aquifers when sufficient water reaches them.
Water for Earth will leverage the EM Locator Technology innovation to enhance large-scale rain harvesting. By constructing these 1-acre wide percolation ponds in the correct locations, more than 1-acre foot of rain per year could be harvested that was previously evaporated.
The sloped berm construction by the landowner is fairly straightforward. They will remove 2-feet of dirt from the center of the zone and build a 3% slope to the outside edge.
This may look like a typical pond, but its not. It's literally designed to drain rainwater into the ground. Thanks to the EM Locator Technology system, Water for Earth will position an aquifer recharge zone over an identified aquifer entry point where it could put more than 325,000 gallons of water into an aquifer every year. That's enough water to support 5 houses - from only 1-acre!
