About Water Well Drilling

Water well drilling is an age old method for reaching water held in aquifers. Those are underground layers of permeable rocks that hold water. Let's take a look at these wells and how they're drilled.

Most people would know a water well if they saw it.  It consists of a shaft and some device to pull water from the shaft.  Some of these have a nothing but a bucket on a rope.  The bucket is tossed into the well then drawn up on the rope.  In some there's a simple crank to pull the bucket back up.

Water well drilling reaches the water held in those porous rocks. The water is generally full of minerals.  It has a kind of gritty texture and a metal aftertaste.  Such water is often softened before use.  That removes the minerals, some of which can be toxic in large enough quantities.

Sometimes water well drilling is followed by installation of a windmill pump.  The windmill uses the wind to provide the energy needed to pump water up to where the people want to drink it.

Gravity provides the water that water well drilling reaches.  Water is pulled down into the layers of porous rocks by the force of gravity.  Most of this originates as rain or snow.  It accounts for about 20% of the fresh water used in the United States.

Water well drilling takes a number of forms.  Digging can create a dug well.  Stones line the walls to keep the well open.  Driven wells are created by hammering a point into the ground.  Pipes are attached to it.  Then a pump is installed to pump water through the pipes.  Rotary drilled wells can reach much deeper water reservoirs.

Well, a water well drilling isn't quite as simple as people think. It can be a deep subject.
