Borehole Drilling
What is a borehole?
A borehole is a drilled shaft typically exceeding a depth of 20 meters and possessing a larger diameter casing. The borehole submersible pump is subsequently dropped inside the casing to pump water.
Installation of a borehole can cost anywhere between R50 000 to R100 000, with the expenses rising depending on factors such as the drilling depth, casing quantity, ground conditions, equipment, labor, and other relevant costs. The installation process may take several days to complete.
A well-maintained borehole can last for a minimum of 20 years, requiring minimal ongoing expenses.
Methods of Borehole Drilling
Air percussion drilling
Pneumatic percussion drilling, also referred to as air drilling or rock drilling, necessitates the use of compressed air to rotate a drill bit and bore through challenging surfaces such as rock.
This drilling technique is primarily utilized for creating deep boreholes.
Mud rotary drilling
To drill through soft terrain using this method, water is essential and is utilized in conjunction with a rotating drill bit.
This drilling technique is primarily utilized for relatively shallow boreholes.
Wellpoints
A wellpoint, essentially a miniature borehole, is a polyethylene pipe with a filtered end designed for installation into soil structures. The wellpoint pump is typically positioned outside the structure.
The cost for wellpoint installation is relatively affordable, with the expense not exceeding R8,000.
The depth of the wellpoint is usually 15 meters or less, and the installation process is expedient, requiring only a day.
Wellpoints are durable and can last for at least two decades, with minimal ongoing maintenance expenses.
It's imperative to note that not all areas can accommodate wellpoints, as the ground conditions may not be conducive to shallow water availability.
Water purification
It is possible to purify borehole or wellpoint water by testing the water quality and installing the correct purification systems. This will then make it suitable for drinking.
This system is also designed to treat borehole or wellpoint water with high iron and chlorine content.
Water purification includes:
- Iron remove
- Remove chlorine
- Odor and improves taste
- Organic contamintaion
- Viruses and bacteria
Operationalizing your borehole during loadshedding.
Are you concerned about exorbitant electricity bills and unreliable power supply? You're not alone!
Unlimited or boundless energy source.
The concept of solar panels involves the strategic placement of solar panels on rooftops or elevated structures to maximize energy output. The solar panels absorb energy from the sun, which is then converted into electrical charges through PV cells within the panel. These charges react to an internal electric field in the cell, thereby generating a flow of electricity. In the context of borehole water supply, the panels power an electric motor that, in turn, drives a borehole pump. The limitless potential of this energy source is awe-inspiring.
The objective is to recover the expenses incurred.
Opting for a solar borehole pump offers several benefits such as reduced maintenance requirements and lowered operating costs. Since the sun is an infinite source of energy, the pump can run during daylight hours without any restrictions. One of the most significant advantages of using this system is that you no longer have to worry about the cost of electricity and water bills.
By installing a solar pumping system, you can reap financial savings, benefit from better operational costs, and contribute towards environmental conservation. This is a wise personal investment that will provide a reliable and long-lasting watering system.
To avoid voltage dips, oversize the inverter by 50% and add capacity for other household loads. Surge capacity varies between inverter brands, so it is difficult to predict. If using a "modified sine wave" inverter with a "solid state" control box, obtain a relay-type box. For a "two-wire" pump, oversize the inverter by 50% or consider a soft start control box. To avoid the need for frequent pump starts, use a storage tank or cistern with a DC pressurizing pump. A lower power solar pump or DC well pump may also be an option.
Refer to the provided chart for inverter sizing guidance.
To ensure optimal functionality of an inverter, it's advisable to oversize it by an additional 50% of its minimum guidelines, plus the watts capacity required to handle other household loads concurrently. This is because an inverter sized merely by the minimum guidelines may cause voltage dips leading to dimming lights during the initial starting surge.
