Most wells do not get their water from underground rivers, but instead get the water from aquifers . Aquifers are layers of rock and soil with water flowing through their small pores. For the most part, there are not giant caves under earth’s surface containing violent rivers of water flowing quickly through them.
How do well drillers find water?
If there are no wells in the area, or not enough information is available on existing ones, the hydrologist may contract with a well driller to put down some test holes . At these holes a pumping or aquifer test will be conducted. These tests indicate the water-bearing properties of the aquifer tapped by the well.
How do house wells get water?
Most wells do not get their water from underground rivers, but instead get the water from aquifers . Aquifers are layers of rock and soil with water flowing through their small pores. ... New water, such as from rain or melting snow, drips down into the ground through the pores and cracks in the rocks and soil.
How do water wells work?
A well is simply a vertical hole in the ground that extends past the water table and into the saturated zone. Water from the surrounding aquifer fills in the vertical hole, or well, which can be pumped. As water is pumped out, water from the surrounding aquifer seeps back into the well borehole.

What are the 3 types of wells?

- Driven wells are constructed by driving pipe into the ground. ...
- Drilled wells are constructed by percussion or rotary-drilling machines.
How fast does well water replenish?
The well’s size, the type of geology the well is in, and the condition of the well all factor into the recovery rate of a water well. Recovery rates can vary from a fraction of a gallon per minute to more than ten gallons per minute .
What happens to the water table when you pump a well?
Pumping a well lowers the water level around the well to form a cone of depression in the water table . If the cone of depression extends to other nearby wells, the water level in those wells will be lowered. The cone develops in both shallow water-table and deeper confined-aquifer systems.
How deep should a well be for drinking water?
The quality of your water depends on several factors including geology and water levels. In order to allow for maximum ground filtration to remove impurities, your well depth should be at least 100 feet . As a general rule, the deeper you drill, it’s more likely that there will be minerals present.
How much do wells cost?
Drilling a residential water well costs $25 to $65 per foot or $3,750 to $15,300 on average for a complete system and installation. Prices include the drilling, a pump, casing, wiring, and more. Total costs largely depend on the depth drilled and the well’s diameter.
Where does well water go after it is used?
Water leaving our homes generally goes either into a septic tank in the back yard where it seeps back into the ground, or is sent to a wastewater-treatment plant through a sewer system.
