Dams are at all-time lows; municipal water costs are rising and people are getting angry. There has never been a better time to examine alternative water sources than right now. Drilling a borehole and becoming self-sustainable might be an option worth considering.

Here's what you need to know about the process of drilling boreholes:

#1 Borehole siting

Determining where the water is and how to reach it, is the first step when it comes to drilling boreholes. It is crucial to employ professionals for this task to avoid drilling into natural hazards or pipelines and cables.

#2 Drilling and Construction

The next step is to commence with the drilling. Special machinery is used to drill deep into the earth's surface. While the depth of an average borehole ranges between 60m - 80m, it can vary greatly from one borehole to another. Construction comes next in the form of steel casing to reinforce the borehole.

#3 Yield testing

Yield testing is done to determine the balance between the greatest amount of water that can be yielded from the borehole and the amount of water that flows back from the neighbouring groundwater source. In order to do yield testing, an aquifer test is carried out. A test pump is installed and water is pumped for a fixed time and set of variables to access the water level in the borehole.

#4 Pump and filter installation

Once the yield testing is done, you'll be advised on the pump you need. The type of pump system will depend largely on your intended use of your new borehole. If your domestic borehole will be used for drinking water, you'll need a filtration system to get rid of contaminants from your water supply.

If you are interested in drilling a borehole on your property, get in touch with one of the experts at Enviro Boreholes. With over 10-year experience in the industry, you can be sure to receive professional and advice and great service.

  • Purpose of borehole - will the water be used for irrigation, domestic usage or to fill up a reserve tank.
  • Flow rate - which means the amount of water to be moved and the pressure needed to get it there
  • Distance the water needs to travel - from under the ground to the top of the borehole, and from the borehole to your tap
  • Refill rate - the water level in your borehole will drop when pumping water and will refill when it rains

Whether you are drilling a new borehole or rehabilitating an old one, it is crucial to use the expertise of a skilled water surveyor. Over time many old wells collapse and are not any longer viable. You can risk losing all your gear should you install the pump before doing a proper evaluation of the borehole.

Additionally, it is vital that you perform a yield test to determine the amount of water in your well. As a result, it's possible to make the appropriate pump choice for your borehole.

Why is it important to do yield testing?

  • To determine borehole potential - To calculate the sustainable yield and hydraulic functionality of boreholes for water supplies.
  • To identify aquifer potential - To assess the hydraulic characteristics of the aquifer to discover the groundwater sources.

The water yield may differ based on the season, the number of new boreholes nearby, the variations in the annual rainfall as well as adverse environmental effects of high transpiration resulting from the planting of large quantities of trees. It is because of this that broad safety guidelines are permitted with the installation of the suitable pumping system. An incorrect pump measurements can harm the borehole and make it unviable. Utilising the proper equipment in your borehole process will guarantee the robustness of your water resource.

A significant element of a borehole yield test is keeping track of the water quality when pumped from the borehole. A water sample is usually taken at the start of the test as well as at the end of the test for a full chemical breakdown, while the electrical conductivity and temperature are typically observed with the water level throughout the test. The water quality is also imperative to see whether it is ideal for household, irrigation or commercial applications. Following South African Standards the highest allowable nitrate content is 10mg/l. An excessive amount nitrate has a significant effect on babies under six months.

How long does yield testing take?

The duration of the test is directly linked to the duty period that the borehole will be pumped at, as soon as the long term pump has been fitted. For example, a borehole delivering domestic water to a residence will have a faster duty period than a sprinkler system borehole. Consequently, the type and process of the test pumping carried out on a household borehole will likely be quicker compared to test for an irrigation borehole.

Other Things to remember.

  • An estimate of the water yield by the driller is not adequate and could be incorrect.
  • If you are fortunate enough to have a borehole that generates a good amount of water, never pump more than you'll need.
  • Groundwater is a highly valuable resource and should not be wasted.

More often than not the continual over pumping of a borehole can result in the eventual total malfunction of the borehole, causing demand to have the borehole re-drilled. This can be a lot.

Many people find an old, non-functioning borehole on their property when moving to a new home and they never know just how lucky they are until faced with drought and water restrictions. The current water situation in South Africa is bleak and getting even worse, especially in Cape Town. With rainy season still a few months away, people are urged to do all they possibly can to save the little water they have at their disposal.

Installing a borehole is classified as a long-term investment and therefore not exactly cheap. Thus, when you are granted with a borehole, even if not in a working condition, you can thank your lucky stars. You are halfway there to having a free water source. The old borehole will have to be assessed to see if it still produces water. After which it would need to be properly cleaned and repaired to develop the borehole yield.

All spring and the majority bottled water come from the ground, even though both spring and bottled water resources pump water from boreholes. 64% of South Africans live on groundwater. If you intend to drink from this water source, it is always advisable to have it evaluated at a water lab to make 100% satisfied that it is fit for ingestion. That is to make sure that the water you consume would cause no threat to your health.

Find a professional to do borehole repairs

It is vital to not try and repair the borehole yourself and risk the water of becoming contaminated. Instead, hire a professional borehole contractor such as Enviro Boreholes to do the borehole repairs for you.

How To Select The Correct Borehole Pump

Once the borehole is drilled, it’s time to install the correct pump. It’s vital that you are aware that deciding on a pump is a critical step in getting the most benefit from your borehole. Why is it so important to choose the proper pump? Although the first expense of the pump is a major factor, the life span cost of owning the borehole also need to be considered.

Typical lifetime costs for a medium-sized industrial pump

Over and undersized pumps are extremely ineffective. They consume a lot of additional energy compared to the quantity of water provided. Additionally, pumps that are energy inefficient will likely have remarkably short periods in between breakdowns. So choosing the proper pump, even if it’s higher in price in the short-term, will be significantly advantageous over the lifespan of the installation.

With all the alternatives on the market, where does one start?

There are elements that you’ll need to take into account:

1. Never service your own borehole

There are elements that you’ll need to take into account:

  • Pump application - What do you intend to do with the water you generate from your borehole?
  • Garden irrigation - Using it for a sprinkler system or hosepipe.
  • Filling up a tank or reservoir
  • Domestic use
  • Farm applications like crop irrigation or water for animals
  • Mine dewatering

These varied applications will demand different pumps.

Pressure and Flow rate

No matter the application, it boils down to two principal components - the quantity of water to be moved, and the force that should be produced to get the water to where it is required

Pumping distance

The water will commence underground and finally be delivered to its endpoint through the pump. The longer the distance, the more powerful the pump will have to be.

Depth of the borehole

Moving water up vertically requires lots of energy, thus a deep borehole will need a much more potent pump than a shallow borehole.

Elevation

If there is a variation in height between the surface of the borehole and the water’s endpoint, then this also needs to be included in the pump selection process, since it will demand additional power from the pump.

Borehole recharge rate

Keep in mind the level of the water is an average measurement. The water level in a borehole will decrease as it is pumped from the borehole, and increase when it's recharged. The borehole’s recharge rate ought to be taken into consideration when choosing a pump, especially when the application includes dewatering.

Remember that pumps have restrictions to what they can do. If the array of duties is small, the selection gets far easier, but if there are several functions to cover, you may find yourself having to make some compromises. Let Eniviro Boreholes assist you with choosing the right.

It is crucial to service and maintain your borehole and pump frequently to have the best return on investment as well as your own private source of running water year-round. By following these easy steps, you can protect your system and water source.

If you are considering becoming self-sufficient, have a look at the considerations below to find out if you too could benefit from installing a borehole on your property.

1. Always use a professional

Whether you are investing in a borehole or maintaining an existing one, it is vital to use an expert in the field. Never attempt to service your own borehole as you will risk contaminating your water source. At Enviro Boreholes, we have ten years’ experience and have drilled over 1000 boreholes in the domestic, commercial and agricultural fields.

2. Don't store or mix chemicals near your borehole

Hazardous chemicals like paint, pesticides and fertilizer can contaminate your water source. A simple spill could quickly leak into the well. Don't ever pour pesticides. Also, make sure you check the borehole cover regularly and be careful when working or mowing around the borehole to avoid damage to the casing.

3. Sanitize your borehole

Anytime repairs are done, your borehole should be sanitized. It's also advised to re-test your water pH-balance to make sure the issue has been fixed.

4. Protect your borehole with a tight-fitting head cap

To protect your borehole, you should ensure it is sealed properly. If not sealed properly with a tight-fitting head cap, it will be easy for undesirables like insects and mice to enter the borehole or holding tank.

Unfortunately, the quality of your water resource can be affected over time, and it is essential to monitor your water quality frequently against bacterial contamination. A simple SANS-241 test should be done at least once per year. It is recommended to seal abandoned boreholes since they can contaminate your groundwater source.

Top Tips For Borehole Maintenance

Borehole maintenance is extremely important whether you use it for domestic or commercial purposes. You won't only extend the lifetime of a borehole with regular maintenance, but you'll also maintain its efficiency and yield.

Here are some things to keep in mind when it comes to borehole maintenance:

1. Never service your own borehole

While it's tempting to try and service your borehole to save costs, it's not a great idea. When you open the borehole cap, you might be doing irreversible damage to your water source since you allow for bacteria to enter your water supply.

Instead, hire a borehole contractor like Enviro Boreholes, who have the right equipment and expert knowledge to keep your water supply safe from contamination and your borehole fully operational.

2. Prevention is Better than Cure

If you leave borehole maintenance for too long, you might eventually incur serious costs. Make sure you regularly inspect your parts to prevent damage. In case you find any defects or corrosion, immediately get in touch with a borehole contractor for advice and follow the required steps to fix it. Even more so when using borehole water for drinking since ignoring these issues might put your family's health at risk.

3. Regularly test your water

Water should be tested for bacteria and contamination frequently, especially if used for drinking. A simple SANS-241 test can be done at any water lab and should be done at least once per annum. If at any time there's a change in the appearance, smell or taste, it's better to perform a test just to be safe./p>

4. Use Borehole Specialists for Maintenance

Before you hire a contractor to do borehole maintenance, make sure they know what they're doing. Only use qualified professionals! Enviro Boreholes has been drilling boreholes and doing borehole maintenance for over ten years. Their staff is highly trained, and customer satisfaction is their primary goal.

Where Does Groundwater Originate From?

Groundwater is a significant part of the water cycle. It comes from rain and hail that saturate into the ground. The water moves down into the earth due to gravity, moving between particles of soil, sand, gravel, or rock, until it reaches a level where the ground is filled up, or soaked, with water. The space that is filled with water is known as the saturation zone, and the surface of this zone is referred to as the water table. The water table could be very close to the ground’s surface, or it might be hundreds of meters below.

While groundwater is present everywhere underground, certain parts of the saturated zone consist of more water than others. An aquifer is an underground creation of permeable stone or loosened substance that can produce usable levels of water when tapped by a borehole. These aquifers can be small, or very big, underlying a large number of square kilometres of the earth’s surface.

Even when groundwater is not used by people, it may continue to play a vital role in the local environment and support rural living that way. Plants may take advantage of it with their roots and animals may drink it when it reaches the surface in the form of natural springs.

If groundwater is below the ground, how can we get it out?

Under natural circumstances, water in aquifers is brought to the surface by way of a spring or may be released into streams or wetlands. Water in aquifers is delivered to the surface naturally by way of a spring, discharged into lakes, streams or the ocean or by drilling a borehole. We can access groundwater through a borehole that is drilled into the aquifer.

As soon as a successful borehole has been drilled, we will equip it with any of the suitable equipment: (the selection is affected by the particular intended use of the water, e.g. for drinking water, water supply to the municipality or irrigation system):

  • Handpump - specifically if the yield of a borehole is small, mostly in rural areas.
  • Windpump - mainly on farms, can sustain higher yields
  • Electrical pump/Diesel pump - typically when borehole yield is significant
  • Play pump - beneficial when borehole yield is low, primarily for water supply at schools.

Boreholes call for advanced technology with the appropriate technical design, along with adequate knowledge about the aquifer. However, the value of high-quality borehole construction and design is frequently overlooked. The duration of a borehole and the performance depend entirely on the materials and the technology applied. Borehole “failure”

Installing a borehole is quickly becoming a viable approach to obtain cheaper water for many people with rising utility costs and water bills. Boreholes can generate a fast investment payback, frequently lowering costs by up to 80% of a metered mains supply, all depending on water usage, of course.

Household Water Use

Properties larger than 500m2 with piped water, typically use up to 46% of their water consumption on irrigation. Making use of municipal water for garden irrigation is rather a waste of drinkable water. By using groundwater for irrigation, people could easily reduce their water bills, while lowering the demand on the municipal water supply. Municipalities use tariff rates that rise in proportion to consumption. This has a tremendous effect on the water bill every the month.

Considering the price of fitting and maintaining a borehole, would be the probable saving in water be worthwhile? To answer that question, let's review the expenses involved in installing and maintaining a borehole in a standard residential home.

Below are the main expenditures linked to installing a borehole:

  • Costs to determine if and where to locate a borehole.
  • Borehole construction cost for:
  • Moving of equipment to the site and back
  • Drilling - charged per-hour or per meter
  • Casing entailing supply and installation of durable casing and screen, gravel pack, hygienic seal
  • Development regarding cleanup of the borehole following construction
  • Pumping test expense for post-construction evaluation of borehole and aquifer effectiveness
  • Hydro chemical analysis - water quality tests for a designated use
  • Installation of a pump and drinkable water storage tank and reticulation system
  • Routine maintenance costs for yearly inspections of the pumping equipment, pipework and repair costs in case there are any failures
  • Electricity fees for operating the pump whenever it is turned on

The average cost of a borehole in South Africa is anything from R60 000 to R90 000.

Below are the main expenditures linked to installing a borehole:

Even though there is a capital layout initially, it is obvious that by using borehole water for irrigating gardens can be a cost-efficient and worthwhile replacement for municipal water. A well-maintained borehole can also be a cost-effective, self-sufficient asset. Despite the fact that preliminary expenses of drilling and equipping may be large, you will find long-term financial benefits to groundwater, especially the fact that borehole water is not nearly as expensive municipal water.
