Water well drilling machines are used to make an “engineered hole” through the soil and rock layers to reach groundwater.
The cost of a modern drilling machine is about $500,000!
Not all water wells are drilled the same way, but rotary drilling is the most common method.
6,000 New water wells are drilled in America every week.
There are more than 15 million wells in use in America for individual homes and farms.
Groundwater is the source of daily drinking water for nearly 150 million Americans.
There are still nearly one million old-fashioned “dug wells” in use. These are very difficult to keep free from water quality problems. Deep drilled wells are much more reliable and provide safer drinking water.
