The Drilling Process
After a site is chosen for a new well, our crew will set up the
drill rig and start by sliding in the first drill rod with the
bit inside the first length of casing. It is then picked up with
the winch line and the drill rod is connected to the top head.
A hardened forged drive shoe is welded on to prevent damaging
the casing end. The top head is engaged, the compressor turned
on, the drillthrough casing hammer is set on top of the casing
and the drilling starts. As the carbide-tipped tri-cone bit is
drilling, high volumes of air are blowing cutting up the casing
and out the chute of the casing hammer. The drill bit is drilling
one to two feet ahead of the casing while the 2500-pound weight
of the casing hammer pushes the casing in the newly drilled hole.
As new casing is welded on, the ground can be checked where the
static water table is. When hard formation are encountered, and
the casing wont follow, then the air-operated casing hammer
is fired to drive the casing ahead. In clean sand aquifers, when
there is enough depth in the water table to meet codes and water
volume requirements, the drill rods are pulled and a screen is
set. In gravel aquifers, water will start gushing out from the
compressor air and the well is developed out. With this drilling
method we use you can see every inch of ground we drill through
and you cannot "miss" any water. Through our experience
we can also get a good idea of the iron content by visually looking
at the color of the sand coming out the chute while drilling.
If the water has high iron and there is a possibility that there
may be better water deeper, we will contact the owner or contractor.
When the well is completed, our pump crew completes
the hookup to the home. We bury the pipe below frost level, set
the submersible pump in the well and set the pressure tank. We
take a sample and send it to a lab for a colifom bacteria test.
We will mail you a copy of your well report and test results from
the lab.
