Commercial Water Well Drilling Service
Wardle Drilling & Geotechnical Ltd has constructed water well boreholes
for clients including breweries, dairies, farms, golf courses, water authorities
and water bottling plants. You do not need planning permission to construct
a water well. If the volume of water required is more than 20m3/day (20,000ltrs)
then a licence will be needed from the Environment Agency and Wardle Drilling
& Geotechnical Ltd can organise and advise on this licensing process.
Wardle Drilling & Geotechnical Ltd undertake each project in a professional
manner and client liaison is very important. The cost of drilling a water
well borehole vary considerably and will depend on many factors as detailed
below, particularly the geographical location of the borehole and the
geology of the site.
Drilling of a typical water supply borehole can include the following:
- Hydrogeological evaluation - A detailed hydrogeological prognosis
report is required to establish the geology of the site this will also
help with the design of the borehole and provide information about the
groundwater level in the area. These are written by the British Geological
Survey or hydrogeological consultants.
- Water well design - Once we have received the prognosis a detailed
borehole quote can be written and following a site visit to meet the
client, establish borehole location and to see if access is acceptable,
then the borehole construction can begin.
- Water well drilling - Wardle Drilling & Geotechnical Ltd own
a fleet of drilling rigs from a small tripod drilling rig to larger
rotary drilling rigs. Access into the site, geology of the site and
depth of the proposed borehole will dictate the selection of the appropriate
- Test pumping and development - When the borehole has reached
the proposed depth a yield test can be undertaken using either a borehole
bailer or a submersible pump. This will establish how much water is
in the borehole and how fast the water level in the borehole recovers
after pumping has ceased. Sometimes, as a condition of the Environment
Agency, a pump test maybe required. Wardle Drilling & Geotechnical Ltd
can organise and undertake pump tests including pre-test monitoring,
step tests, continuous pumping test, recovery monitoring and post-test
monitoring. We can also undertake water sampling and organise laboratory
analysis if that is also required. Wardle Drilling & Geotechnical Ltd
is also experienced with acidisation techniques to improve the yield
of a borehole.
- Pump installation - When the water level has been confirmed
in the borehole the borehole pump can be selected and ordered. Wardle
Drilling & Geotechnical Ltd has extensive experience in the selection
and installation of submersible pumps, and solutions for larger water
supply's can be designed, including custom built booster pump sets to
pump the water greater distances. While the rig is on site the submersible
pump is installed in the borehole complete with the pump power cable.
The borehole is sealed to protect from potential contamination from
the surface with a length of steel casing compete with flange finished
within a manhole chamber.
- Water Supply Connection - Wardle Drilling & Geotechnical Ltd
can undertake all necessary trenching and digging to lay the water supply
pipework and power cable to the appropriate location where the control
panel for the pump will be installed with a pressure tank or water storage
tank where necessary. The electrical control panel needed to run the
borehole pump are bespoke designed and installed to the latest electrical
regulations and appropriate certificates of installation are supplied
by our electrical contractors. Water filters and an ultraviolet unit
can also be installed if required to destroy any bacteria that may be
present in the water. The project will be completed with all final connections
being undertaken to supply the building or end user with water, including
terminating the water supply from the local water authority if necessary.
- Water Pump Maintenance and Servicing - Wardle Drilling & Geotechnical
Ltd undertake post construction services including pump maintenance,
servicing of the pressure vessel and replacement of filters where necessary.
