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 drilling method.
• 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.
