Boreholes – The perfect off-grid solution

In South Africa, there are many homeowners and commercial businesses looking for ways to reduce their reliance on municipal services and secure their energy and water supplies. There is no better way to do this than having a borehole. “A borehole is an asset that should last you at least 10 to 15 years at a very little ongoing cost, provided you buy correctly at the start! If you don’t, it can become a very expensive and time-consuming liability with continual repair or replacement of pumps, the causes of which could either be traced back to poor borehole construction or incorrect pumping or pump installation,” says L’aura James of Borehole Water Association of Southern Africa.

What is a borehole?

A borehole accesses water below the ground, also known as groundwater, unlike municipal water that invariably comes from the country’s dams.  This water is accessed through the process of drilling a hole up to 100 meters deep until a water reservoir is located. Once the borehole has settled and unstable sections have been reinforced, tests are performed on pumping and aquifer to determine yield. After these tests have shown positive results a pumping system is installed and connected to piping to ultimately provide off-grid water suitable for human consumption or irrigation. 

Borehole water is much safer for human consumption as it is not chemically treated like municipal water and is rich in natural minerals and nutrients, however, a purification system may be required depending on the source of the water..

The process of installing a borehole

1. Pre-drilling

Water borehole drilling usually starts with a geological survey and vertical electrical sounding, which attempts to map out the availability of water by taking resistivity measurements using probes at a set distance apart. Before the drilling process commences you may need to obtain the relevant permits and environmental checks according to your country of residence. 

2. Drilling

A drilling rig is required to begin the process where a drill proceeds to dig into the ground whilst extra drill rods are added until the required depth is reached. The next step will involve lining the borehole with steel casing to avoid risks such as collapsing and to eliminate large sand particles from entering the pump. During this process, high-pressure water and air are forced down the borehole to avoid water layers getting blocked. After development, the borehole runs a 24hr test pump to filter dirty water and to check what yield the borehole can supply. Finally, samples are taken for bacteria and chemical analysis.

3. Pumping and piping the borehole

Due to the fact that everyone has different water needs, the pumping system and piping installed within a borehole will significantly depend on the intended use of the borehole water.

4. Cost of drilling a borehole

The cost of a borehole includes a combination of different factors that influence the process used when drilling for groundwater as every borehole is different and requires various techniques to be completed successfully. Therefore, the pricing is a carefully calculated formula according to conditions.  

How is borehole water treated?

Biozone will assess your water analysis and design a tailor made solution. Guaranteeing water that is safe to use, drink and that conforms to World Health Organization drinking water standards (WHO). Through a process of prefiltration, purification and ozonation we are able to transform your water to the highest quality possible.

Common issues found in borehole water in South Africa

Bacteria such as E Coli, Coliforms and Heterotrophic plate count are extremely common in borehole water and are caused by years of contamination and waste matter that seeps through the ground surface and into the underground water source or aquifers. Another common occurrence in borehole water are heavy metals, such as Iron, which are deposited from underground rock formations and/or aquifers. When it comes to the PH guideline, it is more likely than not that the borehole will not meet the requirements as it could either be acidic or alkaline causing the water to be corrosive. Total Hardness is the sum of the Magnesium and Calcium count in the water. Which causes scaling on most appliances within the home such as geysers/ kettles and taps. During the drilling process the borehole may have sediment or particles making their way up into the feed water. All of these common issues can easily be avoided by harnessing nature’s technology with Biozone Manufacturing. 

Load shedding affects water supply in South Africa 

From water abstraction, treatment, and distribution to wastewater reticulation and treatment, energy plays a significant role. Water and electricity may seem like separate resources where in fact the connection between the two is vital, especially in South Africa which has one of the lowest levels of water availability in the world. A considerable amount of energy is needed for the process of pumping, treating, and purifying water and without that energy, treatment plants and reservoirs can’t run effectively which ultimately leads to a water deficit. Load shedding brings the risk that water pumps will not be able to provide pressure to higher-lying areas, fill reservoirs adequately or treat contaminated water correctly, therefore we are at risk of higher water-borne diseases affecting the community through municipal water. Water decision-makers and managers will need to take appropriate mitigatory steps to ensure that the impacts highlighted are stopped or reduced as failure to do so will have costly economic, environmental, social, and health consequences.

The best solution for you lies within Biozone’s borehole and water treatment solutions. Biozone Manufacturing are manufacturers of Ozone technology. This makes our approach to sanitization and disinfection unique as we are able to eliminate bacteria on contact without the need to constantly replenish and store expensive and harmful chemical equivalents. Ozone technology is completely eco-friendly and is far more effective than any other form of disinfection methodology used in modern water filtration.
