Is drilling boreholes a wise investment?

As part of boreholes the construction, drilling equipment is mobilized to the site and returned to the base, drill bits are provided and installed, solid casing and screen are installed, gravel pack is laid, a sanitary seal is installed, and the well head is constructed. How does water benefit you? Would you like to irrigate your garden and top up your swimming pool? What is the best way to provide household water to a small rural community or farm household? Possibly even for an irrigation scheme spanning several hectares.

Boreholes does not have to be registered if they will be used for…- reasonable domestic use (not for commercial purposes)- the watering of animals (not for commercial purposes) With all of the boxes checked, a 20-year life may be expected for the major components. Consequently, it is possible that you may need to deconstruct your property in order to allow access to the drill rig, and once the borehole is drilled, some building work may be needed to restore the area. Be sure to discuss this matter with your drilling contractor and make sure that they can offer a solution that is practical for your property while also giving the borehole the best chance of success.

It is only after a hole has been evaluated in terms of its yield potential that these items can be selected according to amount and demand of water. In the event that the contractor finds the hole to be ‘dry’, you will be responsible for paying the drilling contractor. Good siting procedures should have been followed here. A contract will be reached with the driller so that a hole can be drilled in the ground, with the potential of tapping into a sustainable water source.

It may be advisable for you to select and install a pump and ancillary equipment through a second contractor, or a turnkey solution may be available from your driller. Boreholes are an integral part of the electrical system of your property, and they must be included in the Certificate of Compliance (COC). Borehole yield data can be used to reach a good selection and year-round trouble-free operation. By being informed, an end user is better equipped to recognize the first signs of potential problems and seek professional assistance before expenses mount. A qualified electrician who is familiar with groundwater installations should be hired to perform the electrical work.

It can cost anywhere from R60 000 to R100 000 to install a borehole, the cost depending on the depth of the hole, the amount of casing used, the type of rock drilled, ground conditions, and equipment. Moreover, there is no guarantee you will find water, so there is a risk of spending many thousands of dollars on drilling without a positive outcome. Boreholes, on the other hand, can add substantial value to your property and represent a solid investment for the long run. Installers should use due care to make sure the installation is done properly.
