Drilling A Borehole What To know

Drilling A Borehole What To know

Why do you need water? To irrigate your garden and top up the swimming pool? To provide household water to a small rural community or farm household? Or maybe even to service a multi-hectare irrigation scheme. Whatever the requirement, nothing beats a source of cost-effective water.

If you want an uninterrupted supply of water that is under your control, drill a borehole. Borehole drilling involves drilling a hole into the ground to access the water that lies beneath.  The drilled hole is cased with steel. To collect the natural water and pump it to the surface a borehole pumping system is installed.

Types of Boreholes

There are basically two types of boreholes, commercial and domestic boreholes. As a property owner or tenant, you would be interested to know what type of borehole you will be using.

Domestic boreholes are usually 110mm to 150mm in diameter with a depth of 50m to 70m. Commercial boreholes are slightly bigger, measuring 250mm to 450mm in diameter but not quite as deep. Before drilling the Drilling company will site the area to analyse if there is water or not.

Kind of pump

After drilling the borehole you may want to know what kind of pump you will need. The Drilling company will give you a Borehole report and a license from WARMA which will have information that can help a water engineer identify the right pump for your use.

Pumps fit into three categories: too big, too small or just the right size for the job. Good selection and years of trouble-free operation start with reliable borehole data gathered from the yield test.  The Sales Engineer can also explain the capabilities of the pump and the controls and protection devices they have installed.

As an informed end-user you will be able to recognise the first signs of potential problems and call in qualified help before things get too expensive.

The electrical side of the installation MUST be done by a qualified electrician who is trained or well-experienced with groundwater installations.

Water Storage

Depending on usage there are a number of storage options to choose from. For domestic use, PVC tanks are recommended. surface reservoirs for commercial use. Storage facilities differ in size and installation, others are on the surface and others are installed at heights to inspire gravity and safety of water from pollutants.

Owning a borehole will add significant value to your property and over a period of time, it will represent a good investment. This assumes that the installation is done by professionals and has been operated with due care.
