Today, most
wells are made by drilling into the rock layers using special machines
(drill rigs) to access water deep beneath the surface. The construction
of a water well consists of several elements. Placement of the well
is very important. Local codes require certain distances from septic
and sand mounds, property lines, etc. Another consideration would
be general sloping of the lot and access to the well for future
servicing. The actual hole for most domestic wells is a diameter
of 6 inches. Drilling a well requires the use of special equipment
that requires considerable skill. All wells require casing to protect
the well from possible contaminants at or near the ground surface.
Casing may not be needed for the full depth of the well in solid
rock.
Our job as a
water well construction company is to drill a well that contains
bacteria free water that is of sufficient supply. Most wells that
we construct are of sufficient supply but in some instances a very
deep well of limited supply will have to suffice. The importance
of this bacteria free water is two fold in that the steel well casing
we install is put in place and grouted to prevent surface water
from entering the well. By doing this, all water that enters the
well enter from below the casing, letting the ground be its purification
method. If a casing is faulty it could let undesirable water enter
the well and ground water supplies resulting in the requirement
that casing must be at least 12 inches above grade or flood plain
to keep surface water out. One low or leaking casing is not only
a hazard to the property that it exists on but all ground water
that is in direct contact with this water, in essence contaminating
the ground water systems in that area. When we find water containing
bacteria, the source has to be stopped, not covered up in the building
with some sort of disinfecting device.
After drilling
operations are complete, a trench is dug to connect the well into
the building. Submersible pumps are installed to raise the water
to the surface and pump it to the pressure tank in the house. We
use Goulds and Grundfos stainless steel submersible pumps because
we feel they are the best products on the market. Through our years
of experience we have found that these products last longer and
require little service for 10-20 years.
Well
tanks are installed in the house for storage. We feel that the bigger
the tank the better the job. Most wear and tear of the pump is during
starting and stopping. By having more water on store by having the
largest tank for the space available should prolong the life of
the pump. With a larger tank the pump will run for longer periods
and stay off for longer periods. With a small tank, the pump will
be turning on almost every time the faucet is turned on or a toilet
is flushed. Frequent starts and stops create excess wear and tear
on the pump.
