Determining the Ideal Spot for Your Borehole Filtration System

Before drilling, our team conducts an on-site visit. The reason for this is two-fold; to ascertain the best access point for our rigs onto your property and to gain a better understanding of your specific water requirements. This, in turn, allows us to design your borehole filtration system and install it in the most suitable location. It is also important to send a water sample to a laboratory for chemical analysis to determine its quality, because, even when it is only used for irrigation purposes, the water could still affect crop and plant growth.

The Importance of Testing the Quality of Borehole Water

Similar to surface water such as rivers, groundwater flows in specific directions. As it moves through the ground, it can dissolve minerals or chemicals and transport contaminants such as pesticides. Unfortunately, humans also contribute to aquifer pollution in the form of man-made fossil fuels, oils, and fertilisers, to name a few, which is why your borehole water needs to be tested before use. Where some contaminants purely produce discolouration and an unpleasant smell due to the iron oxide content, others are a potential health risk, such as arsenic, nitrate, and pesticides.

Regular testing of borehole water quality is crucial for maintaining a safe and reliable water source. Test results provide invaluable insights into specific water supply issues, enabling us to take appropriate measures to protect the source from contamination and ensure effective treatment. Assessing the water for its intended use such as livestock watering or drinking is essential for informed decision-making about present and future water management and usage.

Health Risks Associated with Contaminated Borehole Water

Natural water sources can sometimes contain elevated levels of iron, fluoride and other minerals, as well as bacteria. While small amounts may not significantly affect us, vulnerable individuals like the elderly and infants are at risk. For instance, high nitrate levels can be particularly dangerous for babies under six months old as this mineral interferes with the blood’s oxygen-carrying ability. High sulphate levels can lead to diarrhoea and gastrointestinal discomfort and while fluoride is a vital micronutrient, excessive intake can cause dental issues.

Protect Your Borehole

There are proactive measures you can take to keep borehole water clean and uncontaminated, especially if your borehole installation is your only supply of drinking water:

• Understand your aquifer – learn about its location, direction of flow, depth, and source.
• Be mindful of catchment activities – be aware of activities in the area that can have a direct impact on water quality.
• Protect your borehole – whether installed on private, commercial, or agricultural property, keep pollutants away from the borehole head. This includes rubbish, animal waste, pesticides and compost.

Taking these measures doesn’t mean that you should stop testing the water once your borehole filtration system is installed. We recommend that your water is tested at least once a year to ensure the health and safety of those who consume it.

Upgrade Your Water Quality

Borehole filtration systems are not one-size-fits-all solutions. To determine the appropriate system, we need to understand your water’s intended use. After receiving the laboratory test results to determine the water quality, we can assess whether you require basic filtration or a more advanced system with a UV sterilizer. If the borehole is solely used for irrigation and is odourless, colourless, at the correct pH level, and deemed safe for consumption, treatment may not be necessary.

Trusting Aqua Boreholes with your borehole water filter system ensures that your supply is free from bacteria and other contaminants and will protect your equipment, such as pipes and taps, from stains and corrosion.

Aqua Boreholes explore the necessity of drilling boreholes in Gauteng and how our end-to-end borehole solutions can provide you, and future generations, with water security.

Why Gauteng Desperately Needs Boreholes

Gauteng’s water infrastructure faces a critical juncture. Insufficient reservoir capacity and delays in crucial infrastructure projects are exacerbating pre-existing challenges. Woefully inadequate maintenance has compounded these issues, leading to several negative consequences which include increased water losses, reduced overall system capacity, and ultimately, an inability to meet the water demands of a rapidly growing population.

As more residents migrate to the area, the strain on water resources intensifies, resulting in more frequent water shortages. Furthermore, the misallocation of funds earmarked for infrastructure development has significantly hampered the province’s ability to respond effectively.

Beyond the borders of Gauteng, South Africa’s vulnerability to drought significantly exacerbates the water crisis. With below-average rainfall patterns and the effects of climate change projecting increased frequency and severity of droughts, these combined factors are bound to have an impact on water scarcity in the region.

Gauteng is Tackling the Crisis One City at a Time

The City of Johannesburg has openly encouraged residents and businesses alike to seek innovative ways of saving water, whether through rainwater harvesting or borehole installations. They have suggested that the more affluent suburbs in Johannesburg consider installing boreholes to lessen the burden on municipal supply. Gauteng has taken further steps by having the Department of Water and Sanitation visit various municipalities in the province with the express aim of educating the populace about water conservation.

How Boreholes Can Lessen the Burden on the Municipal Supply

Boreholes in Gauteng offer the potential to alleviate pressure on the municipal water supply. By tapping into naturally occurring groundwater resources on your property, you can lessen your dependence on the municipal system. With the province’s aging infrastructure, there is a bigger financial investment in treating and distributing the water, money that could be spent on community borehole installations, for example.

Irrigation accounts for the majority of water used in South Africa which can be greatly reduced by borehole water. The benefit of this is two-fold, not only will the strain on Gauteng’s municipality be lessened but residences, businesses and industries won’t be limited by imposed water restrictions. The benefits to the agricultural sector are numerous, among them are year-round crop irrigation which extends the growing season and water security during times of drought.

From flourishing community gardens to promoting sustainable irrigation practices in agriculture, boreholes may just prove to be the answer to many of the province’s water woes.

Steps Towards a Water Secure Future

As gloomy as the predictions are, there is hope. You can take steps towards alleviating your water concerns by partnering with Aqua Boreholes, a company that is committed to addressing the water security challenges in Gauteng and surrounding areas with professional borehole installation services.

We would like to make you aware of the limitations of accessing groundwater and what will happen to your saturated water zone if it runs too low before we delve into borehole yield testing.

How Borehole Yield Testing Prevents Aquifers from Running Low

A significant portion of South Africa’s aquifers are not realistically recoverable. This limitation stems not only from the geological makeup and inherent characteristics of the aquifers themselves but also from the need to avoid excessive drawdown. Excessive lowering of the water table within an aquifer can trigger a cascade of negative consequences. For example, in coastal regions, saltwater intrusion can occur, contaminating the water resource with brackish water. Even inland aquifers are not immune as over-pumping can cause the migration of lower-quality water from adjacent formations, leading to a deterioration of the aquifer’s water quality overall.

Unlocking the Potential of Borehole Yield Testing

Borehole yield testing is a crucial step in assessing the viability of the drilled borehole. It involves pumping water out of the borehole at a controlled rate and monitoring the water level drawdown within the borehole itself. This provides our team at Aqua Boreholes with valuable data on the aquifer’s ability to replenish the pumped water ensuring sustainable water extraction over time. Our yield test also includes monitoring the water quality throughout the process to gain insights into the aquifer’s characteristics.

Assessing the Effect of Pumping on an Aquifer

Borehole yield testing plays a critical role in the successful completion of your borehole project. By analysing the test results, Aqua Boreholes can select an appropriately sized pump, ensuring controlled groundwater withdrawal and preventing over-pumping of the borehole, which can have detrimental consequences.

1. Step Drawdown Test:
   After installing the test pump, we will slowly increase the pump rate at specified intervals. This allows us to measure the discharge rate at every step to ensure the effectiveness of the borehole.

2. Constant Discharge Test:
   For a predetermined time, water will be pumped constantly from the borehole. The length of this test is proportional to the anticipated yield. Throughout this test, the water levels are meticulously recorded and analysed to establish sustainable extraction rates.

3. Recovery Test:
   In this test, the pump is deactivated so that we can measure the rate at which the aquifer recovers. The data collected from this test is highly valuable for assessing the impact of pumping on the aquifer and identifying any potential dewatering issues.

Testing, Pumping and Recharge

A properly conducted yield test provides invaluable data for hydrological analysis. By examining the drawdown rate within the borehole and correlating it with the water strike depths, a sustainable pumping rate can be calculated. This rate ensures that the water level remains above these critical depths over extended periods. During these intervals, natural processes like rainfall and aquifer recharge can replenish the extracted water volume.

The Delicate Balance Between Science and the Environment

As dependent as we are on science to provide us with the data needed to detect water and the state-of-the-art equipment to extract it, water extraction must be done ethically. Securing sustainable groundwater access requires a holistic approach, incorporating a commitment to ecological guardianship and responsible resource management.

Aqua Boreholes will always remain at the forefront of responsible and ethical drilling practices. By actively pursuing innovative and sustainable water extraction techniques, we ensure the long-term viability of this long-term finite and vital resource.

The Importance of a Professional Borehole Pump Installation

Attempting a borehole pump installation on your own can lead to a multitude of problems down the line. A slight misjudgement in the alignment of the pump and improper pipe installations can cause premature failure, leakage and ultimately the pumping system’s collapse. Furthermore, oversizing or undersizing the pump can lead to inefficiencies which is why it is best to leave the installation in the hands of the experts – Aqua Boreholes.

Selecting the appropriate pump for a borehole system requires an understanding of the water’s journey from source to tap. Typically, two pumps are used; a primary pump responsible for extracting water from the aquifer and a secondary pump, often referred to as a booster pump, that increases the pressure for distribution through pipelines to various outlets. The size and specifications of the pumps are dependent upon the intended use of the borehole water. For instance, applications requiring high flow rates, such as irrigation systems, may necessitate a more powerful pump compared to those used for domestic purposes.

Sizing Up the Pump for the Application

Before the borehole pump installation can be done, we need to know what your borehole is going to be used for. Every application requires a bespoke system. For example, if the borehole is drilled for agriculture, we need to know if it is purely for crop irrigation or if it includes water for livestock. If your borehole is at your residence, is it for irrigation, greywater or the entire household? This information will inform the pressure and flow rates.

From an Aquifer to Your Taps: The Purpose of Pumps

Your borehole water needs to cover quite a distance, starting underground and ending at the highest elevation. Getting the water out of the borehole requires submersible pumps as they are uniquely engineered to remain submerged in the water and draw it from the underground source to the surface. At surface level, a booster pump moves the water horizontally through the piping system to the delivery point. If there is a difference in height between the top of the borehole and the ground elevation outlets, it needs to be factored into the pump selection, as additional pressure is needed to move the water upwards.

If you choose Aqua Boreholes to do your borehole pump installation, we will do the groundwork for you. We calculate the diameter of the submersible pump required against the diameter of the borehole and size the pipes to prevent friction which in turn keeps your energy costs low. We do our utmost to safeguard the integrity of the borehole and pumps with the aim of extending their lifespan.

Ensuring the Longevity of Your Borehole    

By following recommended protocols and utilising high-quality components, Aqua Boreholes minimises the risk of leaks, malfunctions and breakdowns. Our proactive approach means that we can offer you a more dependable water source and a properly installed system that is easier to maintain, with a reduced need for costly borehole pump repairs or replacements down the line.

Whether you have chosen to drill a borehole as a backup to the municipal supply or as part of an off-grid system, it represents your water security. Therefore, as effective as a borehole pump installation is to bring water to where you need it, it is equally vital to ensure that your water reserve is used responsibly and sustainably.

The Sustainable and Reliable Alternative

Unrestricted irrigation

Borehole installations offer significant cost savings compared to municipal water. Not only does this present you with the option of irrigating when you want to, but it also encourages the cultivation of flourishing gardens, potentially enhancing your property’s value and aesthetics. Boreholes can even be used to support the establishment of vegetable and herb gardens, further promoting self-sufficiency and giving you control over vital food sources.

Better water quality

Municipal water undergoes rigorous treatment to ensure safety, which can include adding disinfection chemicals. Borehole water, on the other hand, is naturally filtered through the ground, potentially retaining minerals that some find beneficial. While borehole water may appear purer, it can sometimes contain contaminants such as bacteria. It is advisable to have the water tested so that you can make an informed decision about its suitability for consumption and possible filtration requirements.

Lessening the strain on the municipal supply

The installation of a borehole on your property presents an opportunity to lessen the strain on your area’s municipal water supply. By harnessing the naturally occurring groundwater resources beneath your property, you can reduce your reliance on the municipal system. This approach promotes environmental sustainability, as the treatment and distribution of municipal water often require a significant expenditure of resources, particularly in cities and towns with ageing infrastructure.

Enhancing the value of private and business properties

The presence of a functional borehole on your property can significantly enhance its value. Borehole installations represent a unique and desirable amenity, differentiating your property from others on the market. Moreover, access to a sustainable groundwater source offers the distinct advantage of continued water availability during periods of drought or water restrictions. This independence results in increased property value, as it shows potential buyers that the property can meet both personal and commercial water needs regardless of external circumstances.

High-volume water use

By having a borehole installed, you greatly reduce your reliance on the municipal supply for high-volume water use such as large-scale irrigation, swimming pool maintenance as well as DIY and major construction projects. As every household and business is limited to the amount of water that can be used monthly, not only will you enjoy lower water tariffs, but you will potentially avoid being fined for excessive water use during times of water restrictions or periods of drought.

Long-term water sustainability

A well-maintained borehole offers a highly efficient and long-term water solution. Although the initial investment may seem to be substantial, professional borehole installations with routine maintenance, can provide a reliable water source for decades to come. During this time, operational costs are minimal.

This sustainable solution affords year-round access to water which can be used for greywater or as part of an off-grid lifestyle. Bear in mind that water is a finite resource and should be used responsibly.

Looking Toward the Future

Increasing population rates combined with insufficient rain, global climate change and continuous drought as well as urbanisation, deforestation, industrial processes, and poor waste management are significantly reducing usable water resources. With poor maintenance and lack of investment in water resources adding to the burden, borehole installations will significantly alleviate the reliance and strain on the current supply. Access to a reliable water supply can comfortably sustain communities, businesses, households and industries.

Finding a Reputable Contractor

By familiarising yourself with the borehole drilling process, not only do you gain valuable knowledge about installations, but it puts you in control and helps avoid any potential misunderstandings. Start by finding a contractor who can give you a comprehensive quotation detailing the work that needs to be done, is completely upfront about costs and deliverables and can provide you with customer references on previous installations. By doing this, both parties will be clear on responsibilities and expectations.

What you can expect from Aqua Boreholes is a seamless process, guiding you from the initial drilling stages to enjoying clean, fresh water. We ensure a transparent process with no unexpected surprises.

Where to Start Drilling?

Creating a clear path for the drill rig might involve some initial deconstruction on your part and once the borehole has been successfully installed, some minor landscaping may be needed. Planning for this ensures that the drilling can be done as smoothly as possible. An added advantage of selecting Aqua Boreholes as your preferred contractor is that we understand the access limitations on residential properties and have compacted drill rigs that can be used in these instances which translates to minimal structural disruption.

Tapping into an Underground Water Source

It makes it easier to tap into an underground water supply if there are producing boreholes in your area. However, this doesn’t guarantee your access to water. Carrying out water surveys by employing the services of a hydrogeologist beforehand is a better guarantee of determining where intersecting aquifers are situated. These professionals have access to published data, geological surveys of the sub-surface conditions in the area and specialised equipment to establish the presence of water.

By successfully using these techniques to access an underground water source, we can equip you with the information you need to better plan the cost and effectiveness of the project. We have proven time and again that water can be found in the most difficult places when using state-of-the-art technology.

Determining the Sustainability of the Borehole   

After the water table has been intersected, the sustainability of the borehole needs to be determined through several yield tests. This test involves installing a test pump, pumping the water at controlled rates, and monitoring any decline in the water level. These tests are crucial as they determine the maximum amount of water that can be pumped against the amount of recharge from the groundwater source. The total water extracted must always be less than the natural recharge rate. Otherwise, you stand a chance of the aquifer running dry.

At Aqua Boreholes, these tests are included in our range of services as we want to ensure that your borehole installation bears sustainable yields for decades.

Complete System Installations

Whether your borehole drilling contributes to your off-grid lifestyle, is purely for irrigation purposes or is used as greywater throughout the home, an on-site visit will enable us to determine the best placement of pumps, tanks, and, if needed, filtration systems.

At Aqua Boreholes, we believe that open communication, rigorous environmental impact assessments and adherence to strict regulations are crucial for ensuring that borehole drilling remains a tool for scientific progress, not environmental degradation. The future of this practice hinges on responsible and ethical implementation making sure that we serve you without compromising nature’s delicate balance.

Borehole Drilling Goes Beyond Selecting the Drill Site

To gain a better understanding of how crucial maps and surveys are to borehole drilling, we would like to take you on a journey that starts below the surface and ends with you having adequate access to water for decades.

1. What is an aquifer?
   Rainfall follows a natural water cycle path where it flows into rivers, streams and dams. Some of the water will be evaporated and some will filter through soil and rock layers below the surface. This hidden water accumulating in tiny spaces between soil, sediment and rock particles eventually becomes groundwater. If there is enough of it, it forms a vast underground reservoir known as an aquifer.

2. Determining sustainable borehole yields:
   This is where the science comes into play. The geology of an area plays a vital role in a borehole’s sustainability. Factors such as the geological setting and rainfall in the area need to be taken into consideration as a borehole cannot be considered sustainable if the natural groundwater recharge isn’t adequate. The quality of the groundwater is dependent on rock-water chemical reactions as well as the amount of precipitation in an area. It is important to note that in semi-arid regions the rate of evaporation often far exceeds precipitation making the groundwater more saline (salty).

3. The maps tell a story:
   At Aqua Boreholes, we don’t leave anything up to chance and rely heavily on detailed geological maps to give us an indication of what lies beneath the surface. Consulting with qualified geologists allows us to identify and conceptualise the preferred drill site. What geophysical science explores is how the earth’s materials such as sand, clay and rocks respond to different signals like magnetic fields and seismic activity. Geophysical studies are often conducted in areas where there are existing boreholes which aids in developing a hydrogeological model before borehole drilling commences.

4. Ethical drilling practices:
   As drilling specialists, we ensure that from drilling to drinking, the entire process of your borehole installation is done ethically and above board. With yield tests, we will determine the balance between the maximum amount of water that can be extracted against the amount of water that recharges from the surrounding groundwater source. We follow responsible drilling practices and will never allow a borehole to be pumped in such a manner that the water level reaches the main water strike. Water is a finite resource which must be preserved for future generations.

Responsible Groundwater Development

For the trained professionals at Aqua Boreholes, proper planning is key. Groundwater development and extraction require a scientific approach. From finding the earth’s sweet spot to meticulous borehole drilling itself, we ensure that the proper procedures and standards are met. We will guide you through every step, including yield testing, infrastructure set-up and even monitoring, to make sure that everything runs smoothly.

By following the right approach, you will be investing in a reliable water source that will quench your thirst for a lifetime. Entrust your borehole installation to a company that taps into the power of responsible groundwater development, Aqua Boreholes. Contact us and we will gladly arrange an on-site visit to discuss your specific borehole requirements.

Boreholes Offer Access to a Critical Lifeline   

Drilling into the depths of the ground in search of the earth’s most precious resource is a technique that dates back over eight centuries. Boreholes as a reliable, plentiful supply of water were introduced by ancient Egypt using tools with copper “drill bits” to drill a water well. Where crude buckets were used to bring water up from the modified aquifer, technology has developed in leaps and bounds enabling companies like Aqua Boreholes to bring this finite resource from the ground to your taps.

Tap into Water Freedom

Let the experts at Aqua Boreholes take you through the main benefits of a borehole installation and delve into how this long-term alternative water source sustains more than just households and businesses.

1. Water security:
   Drilling a borehole offers you what you need the most, water security. It frees you from ageing infrastructure, contamination scares, water restrictions and drought. This independence brings you peace of mind knowing that in times of crisis, your taps will keep on flowing meeting your essential requirements. When you invest in such a water supply, you navigate water challenges with resilience, ensuring that you have a reliable supply when you most need it.
2. Improved water health:
   The municipal water supply that you rely on is doused with chlorine to make it safe for human consumption. This unfortunately comes with the downside of removing naturally occurring nutrients and minerals normally found in underground water sources. Underground water sources are not subject to the same pollutants and contaminants of surface water making it the healthier choice. In addition to improved water health, you are doing your part for the preservation of dams, rivers and streams when you tap into an aquifer.
3. Cost savings:
   At the start of the process, it may seem that drilling for a borehole is a costly investment. However, when you consider the advantage of water security and a significant reduction in your monthly water account as an added benefit, it is a wise and prudent decision to make. With a borehole, you have control over water usage. If you are in doubt, it is important to bear in mind that the capital investment will be offset by long-term financial benefits.

Looking at the Bigger Picture

At Aqua Boreholes, we look towards the future and urge you to use your water supply conservatively. Tapping into an aquifer doesn’t equate to an infinite water source. Every time you use your borehole water, think of the farmers who rely on it to sustain crops and feed livestock. Think about communities that suffer water scarcity and how such a water source can change their lives. At the end of the day, water security goes hand-in-hand with food security, so it is still important to protect our most valuable resource.

Sustainable Drilling Practices

Choosing Aqua Boreholes as your installation specialist means that you are aligning your long-term interests with a company that is passionate about environmental sustainability. We study geological maps and conduct hydrogeological surveys as well as yield tests to make sure that the total abstraction from your water source will always be less than the natural groundwater recharge. These practices ensure that aquifers remain replenished, and your water supply doesn’t run dry.

When it comes to water security, you can rely on our team of qualified electricians, plumbers, filtration experts and master drillers to design your borehole system according to your unique specifications. Contact us and together we will secure your access to water for future generations.

Finding Water Before Drilling Commences

A borehole is an investment in water security and for some, it forms part of the off-grid lifestyle that sustains them. There is a misconception that since approximately 70% of the earth’s surface comprises water, it is easy to drill a hole in the ground and tap into an infinite water supply. If that were true, then arid areas would no longer suffer drought and other regions would not be burdened with severe water restrictions. At Aqua Boreholes, we make it our priority to ensure that your water detection is assured using surveys and mapping. With the latest technology at our disposal, we have proven time after time that water can be found in the most difficult places – our 99% success rate proves it.

Importance of Hydrogeological Surveys and Geological Maps

While drilling for water may seem like a gamble, conducting a thorough hydrogeological survey transforms it into a calculated investment. By providing a clear picture of the hidden depths and underground rock formations, these surveys pave the way for sustainable water use. Part of successful water detection is consulting maps on the geology of your area. The survey conducted by a hydrogeologist provides valuable insight into your property’s geological setting.

Forget wishful thinking, chance or even relying solely on geophysics. When it comes to groundwater prospecting, let geology be the compass. Understanding subsurface geology and its hydrogeological ramifications is the critical first step in defining optimal drill spots. Not only does this useful information plot the site where we can start drilling but it also indicates as to the potential of the borehole and the water quality.

Determining the Borehole’s Yield

The geology of the area is relied upon for water detection and yield tests are conducted to establish the balance between the amount of water that is drawn and the replenishment of the underground water source. These tests are not only crucial for the sustainability of your borehole but also for the environment. Beyond basic water detection, a comprehensive hydrogeological assessment delves deeper. It probes the catchment’s vulnerability to contamination, scrutinises the water source for potential pollution pathways and rigorously analyses the aquifers themselves. This includes pinpointing hydraulic properties, flow direction and flow rate providing a complete picture of the groundwater system.

We aim to provide long-term sustainable water solutions that benefit you without hindering nature’s delicate balance. To ensure the longevity of the yield, pumping from a borehole must remain below the surrounding aquifer’s natural recharge rate. Additionally, it is crucial to avoid pumping the water level down to the main water strike zone typically associated with fractures. Depleting this recharge point can significantly reduce the yield and eventually lead to the borehole running dry.

Water Quality Reports

As much as water detection leads to locating an underground water supply, the water quality needs to be tested to better understand the behaviour of the aquifer (replenishment of water levels) and to determine whether the water can be used for domestic consumption, irrigation or industrial purposes. Based on the report, filtration systems may need to be installed, especially if the water is to be used domestically.

At Aqua Boreholes, we never leave anything to chance. After a thorough study of geological maps and hydrogeological surveys of your area, you should have peace of mind knowing that upon our drill rig’s arrival, we have detected water. Get in touch with us to learn more.

Offering a Step-by-Step Sustainable Solution

Aqua Boreholes would like to delve into what you can expect from us when drilling a borehole, addressing any gnawing concerns before taking the plunge.

1. Detecting an aquifer

Tapping into an underground water source may seem simple; however, it can be problematic if there are no other existing borehole systems in proximity. Due to the costs involved in drilling a borehole, we need to be sure that there is an aquifer before we will arrange a site visit. Employing the services of a geohydrologist will confirm the presence of water. With a 99% water detection success rate, there is a good chance that your consultation with us will happen sooner than you think.

2. Consultation

Arranging a consultation at your premises gives us a better understanding of the topography, which affects our choice of drill rig on the day as well as accessibility to the drill site. We will also need to know whether the borehole installation will act as a backup to municipal supply or as part of an off-grid system. These are our concerns as we want the process to run as smoothly as possible and ensure that pumps, tanks, and filtration systems if required, are installed in the right area and according to your specifications.

3. Drilling a borehole

Before we drill, you must be prepared for the possibility of unavoidable garden damage and may need to warn neighbours or businesses nearby that they can expect noise. Depending on the region and geology, we could intersect a water table at 30m or 150m. After stabilising, well yield tests need to be conducted to establish the viability of the borehole.

4. Yield tests

We will install a test pump to determine the drawdown level of the underground water supply. These tests assist us in establishing the potential of the borehole and estimating a sustainable yield. This is vital as it determines the balance between the maximum amount of water that can be pumped out of the borehole and the amount of water that is recharged back into the aquifer.

The amount of water drawn must be less than the groundwater’s recharge rate. Otherwise, your borehole will run dry. We will also have a sample of the water tested by a laboratory to determine if it’s safe for use.

5. Installation of pumps, water tanks and filtration systems

It is important for us to know what the purpose of your borehole water is because, once our qualified electricians and plumbers are on site, they need to ensure that your system is set up correctly for the desired application. For example, an off-grid water system may need water filters installed and we must ensure that their specifications are aligned to the water quality report.

A borehole promises decades of water but neglecting the crucial early stages can turn your water security dreams into a nightmare.
