As it is porous, the basin contains natural aquifers, very important in maintaining a water supply for both irrigation of crops and drinking water.

Rainfall in the region occurs 50 days per year, with normal intensities of 10 mm per day on average, supporting the endemic vegetation and natural aquifers.

Much greater potential may be available from this approach than from conventional tapping of natural aquifers.

Despite occasional droughts throughout central Indiana, Fortville has a steady and reliable supply of water because it is situated over a natural aquifer.

The water will not be used immediately, but will be stored in natural underground aquifers.

The water supply is a natural aquifer.

The earth's crust contains stratas of hot, dry rock and natural aquifers - pockets or streams of hot water.

Spring flow has also been reduced due to well pumping and overgrazed soil, which lowers the amount of water that can normally be found in natural aquifers.

The village is located on the edge of a large natural aquifer which accounts for the large number of springs in and around the area.

The constraint is the limited land area to catch and store the rainfall, and the absence of natural aquifers and lakes.
