Borehole Drilling
What is a borehole?
A borehole is a drilled shaft that typically exceeds a depth of 20 meters and features a wider diameter casing. A submersible pump is then placed within the casing to extract water.
The cost of installing a borehole ranges from R50,000 to R100,000, with expenses increasing based on factors such as drilling depth, the amount of casing needed, ground conditions, equipment, labor, and other associated costs. The installation process can take several days to finalize.
With proper maintenance, a borehole can last at least 20 years and requires 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, which is essentially a small borehole, consists of a polyethylene pipe with a filtered end designed for installation in soil structures. The wellpoint pump is generally located outside the structure.
The installation cost for a wellpoint is quite reasonable, typically not exceeding R8,000.
The usual depth for a wellpoint is 15 meters or less, and the installation process is quick, often completed in just one day.
Wellpoints are built to last, with a lifespan of at least twenty years and minimal ongoing maintenance costs.
However, it's important to recognize that not every area is suitable for wellpoints, as ground conditions may not support 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.
You will experience four stages of filtration.
1. Sediment filtration(5 micron) involves using a micron sediment filter designed to eliminate sediment, silt, rust, and loose particles, ensuring that the water remains clear.
2.Activated carbon filtration effectively eliminates chlorine, volatile organic compounds, as well as unpleasant tastes and odors from water.
3.The polishing filter(1 micron) serves as a finer filter positioned before the UV light. Its purpose is to guarantee that the UV light receives clear water, which in turn facilitates effective penetration of the UV light through the water.
4.A sterilization filter featuring a stainless steel UV light that purifies water by eliminating 99.99% of harmful bacteria, all without the use of chemicals.
1 stage filter
- Removes sediment and loose particals.
- This this can be used for washings machines and toilets.
2 stage filter
- Removes sediment and loose particals.
- Improves taste and odour
- Removes chlorine
- Removes organic contaminants
- This this can be used for washings machines and toilets.
3 stage filter
- Removes sediment and loose particals.
- Improves taste and odour
- Removes chlorine
- Removes organic contaminants
- Includes final polishing filter
- This this can be used for washings machines , toilets and geysers.
4 stage filter
- Removes sediment and loose particals.
- Improves taste and odour
- Removes chlorine
- Removes organic contaminants
- Includes final polishing filter
- Destroys viruses and bacteria
- This this can be used for washings machines , toilets ,geysers and for drinking.
This system is also designed to treat borehole or wellpoint water with high iron and chlorine content but not for drinking.The water treatment process consists of two stages. The first stage involves installing an inline chlorinator, while the second stage allows the water to flow through a filter designed to eliminate iron.
Water purification includes:
- Iron remove
- Remove chlorine
- Odor and improves taste
- Organic contamintaion
- Viruses and bacteria
Implementing Your Borehole During Load Shedding.
Are you worried about high electricity bills and an inconsistent power supply? You're certainly not
An endless or limitless source of energy.
The idea behind solar panels is to strategically install them on rooftops or elevated structures to optimize energy production. These panels capture sunlight, which is transformed into electrical charges via photovoltaic (PV) cells inside the panels. These charges interact with an internal electric field within the cells, creating a flow of electricity. In the case of borehole water supply, the panels energize an electric motor that operates a borehole pump. The boundless potential of this energy source is truly remarkable.
The goal is to recoup the expenses that have been incurred.
Choosing a solar borehole pump comes with numerous advantages, including decreased maintenance needs and reduced operating expenses. As the sun provides an endless energy source, the pump can function freely during daylight hours. A major benefit of this system is that you can eliminate concerns about electricity and water bills.
By implementing a solar pumping system, you can enjoy financial savings, improved operational efficiency, and make a positive impact on environmental conservation. This is a smart investment that ensures a dependable and long-lasting watering solution.
To prevent voltage dips, it’s advisable to oversized the inverter by 50% and account for additional household loads. Surge capacity can vary across different inverter brands, making it challenging to anticipate. If you are using a "modified sine wave" inverter with a "solid state" control box, consider acquiring a relay-type box. For a "two-wire" pump, increase the inverter size by 50% or think about implementing a soft start control box. Additionally, to minimize frequent pump activations, use a storage tank or cistern alongside a DC pressurizing pump. You might also explore the option of a lower power solar pump or DC well pump.
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.
