A borehole is drilled
vertically into the rock beneath to locate aquifers. The ideal
diameter of the borehole drilled is 200mm (8"). The discovered
aquifer then provides you with a source of water. The borehole is
lined and a submersible pump is installed to bring the water to the
surface.
The cost of a
borehole will vary a little depending upon the land type.
However we can give you an indication by phone although it
is more accurate to do this with a BGS land report. We will
also calculate the amount of water that you will need.
After striking
water, we can calculate the amount of supply available from
the well by completing an air lift test. This will give you
a close estimate of the supply available at the time of
drilling.
In April
2006 there was an European directive which came into force.
This has a requirement
that
commercial companies attain authorisation to extract water.
However an amount of 2200 gallons per day can be extracted
without registration permission.
The amount of time it takes from commencement of drilling
until a regular supply is attained does depend on the rock.
However, the borehole should only take a day or two and then
after installation of the pump and water testing, the supply
would normally be available at the end of 3 weeks.
The water is
always required to be tested for drink quality, (potable), W
James Campbell will arrange for the testing and install
filtration if necessary.
