The Low-Down on Boreholes

A borehole(also known as a tube well)is as a structure used to expose water that is hidden in the interstices or in the cracks of a rock embedded in the sub-soil that is also called the aquifer.

The water can be raised to ground level either by using a simple receptable (eg. Bucket) or a motor driven pump.

Boreholes that are manually dug are one of the oldest sources of water amongst the poorest communities.

In days of old , the boreholes were simply holes dug with absolutely no form of protection against collapsing.

Their inability to withstand harsh weather conditions led to them disappearing over the years. Of course then they constantly had to dig new boreholes because the ones they had previously dug had either collapsed or dried up quickly.


Boreholes remain one of the most effective and reliable sources of water among the poorest communities. Having to travel long distances to get access to water is a struggle many still have to face.

Even though there are rivers in most poor communities, the water from these rivers are not fit for human consumption. These rivers are where people bath, do laundry and for some these same rivers are lavatories.

Thus making it a breeding ground for multiple illnesses. The borehole system however, requires the, to either use a pump or a pulley system to bring the water up to ground level thus reducing but not completely eradicating the levels of contamination.

Manually dug holes are still subject to contamination by humans because they usually only go up to 20m below ground which is very shallow.

Now given the fact that boreholes are used primarily in the poorest communities, these people do not have access to mechanical means of digging the boreholes.

It is only fair to say that drilling and driven techniques need to be enforced around affected areas. It would be a small price to pay so that all people, no matter their social standing, have access to clean and fresh water.

A Dry Faucet

No water making its way to the taps could mean that there is no power coming to the pump.


Air in the pump results in aerated water. This could be caused by a cracked pipe, poor submersion or a faulty valve.

Dirty Water

Dirty yields could be the result of sediment in the pump, which if left too long, will eventually cause a breakdown in its internal parts.

Increased Power consumption

When pumps become faulty they need to overcompensate, which takes up a lot more electricity. This results in higher power costs for you.

The perfect way to access pure and natural underground water is to use a borehole. boreholes have a narrow shaft that is drilled vertically and horizontally into the ground so you can access water underground, this will probably be the purest water you have ever had.

A borehole is used as a water well and is completed by using vertical pipes and screening to keep the borehole from caving in.

Boreholes can be used for a variety of reasons, like the extraction of water, you can use it as a sprinkler system on your property.

Boreholes can be used to measure the temperature, or it can also act as an underground storage for unwanted substances. Boreholes prevent surface contaminations from entering the borehole and protects any installed pump from bringing in sand.  What is a borehole without borehole pipes?

Benefits of borehole pipes

In order to design a water pump, you should account for protective measures, things that will keep your pump running for longer, corrosion and age. PVC piping can ensure that this job will be done and will provide this kind of protection.

  • Corrosion resistant – PVC piping being made from certain and specific materials, it is completely corrosive resistant, making it perfect for borehole pumps which will provide the kind of environment where corrosion thrives.
  • Durable, liable and long-lasting – PVC piping is a long-lasting product, which is why it is used all over the world in buildings and most homes. PVC piping is resistant to wear and tear and other damages.
  • Simple to install – PVC is a very easy material to maintain and very easy to install, thus little tools will be needed to install your borehole piping.

borehole pump

A submersible pump is a mechanical device that serves multiple purposes and is one the most of the most extensively used automatic devices. A submersible pump , also known as a an electric submersible pump or sub pump , is a pump that can be fully submerged in water . The motor is hermetically sealed and close-coupled to the body of the pump.


The main advantage of this type of pump is that it prevents pump cavitation , or the formation of an air bubble , a problem associated with a high elevation difference between pump and the fluid surface. Sub Pumps push the fluids to the surface as opposed to jet pumps having to pull fluids down. Thus making sub pumps more efficient than jet pumps because they don’t use a lot of energy moving water , water pressure pushes the water into a submersible pump which in turn saves a lot of the pumps energy. The pumps are also very quiet due to the fact that they are submerged under water , which also helps with cooling the motor down.

How it works

A submersible pump pushes water to the surface by converting rotary energy into kinetic energy and further converts to pressure energy. This takes place when water is pulled into the pump as an intake , where the rotations of the impeller push water through the diffuser and from there it goes to the surface.


Submersible pumps are used for used for many things. Single stage pumps are used for drainage , sewage pumping , general industrial pumping and slurry pumping. Multiple stage pumps are usually lowered down into a borehole and most typically used for residential , commercial , municipal and industrial water extraction.

Also whilst the pumps themselves aren’t very versatile , the selection definitely is. Some submersible pumps can easily handle solids , while some are better suited for liquids only.

Sewage pump

Side-channel pumps offer the best of both worlds in terms of water pumping solutions, operating somewhere in between displacement pumps and centrifugal ones. They offer a unique and safe way for the transfer of clean fluids, and are used for a wide range of applications across a number of industries. They offer a number of advantages when compared to pumps for other types of fluid control systems, offering enhanced safety, more effective flow properties, as well as reduced NPSH requirements.

Enhanced Safety through Self-Priming

When they are initially run, side-channel pumps function much in the way that displacement pumps do. As the side channels are filled with liquid, however, they start to collect liquid from the outer regions of the side-channels and impeller cells, which allows it to act like a centrifugal pump. This facilitates an important function, namely self-priming. This makes them much safer to use than other pumping solutions.

Gas Transport with Uninterrupted Fluid Flow

Some processes require pumps to evacuate gas at essential points, and this needs to happen without interrupting the liquid flow. Pulsed pressure build-ups in side-channel pumps create an internal multi-stage effect which facilitates gas transport without interrupting liquid flow. This stops the pump from being damaged as a result of dry running, which in other systems, tends to damage pump bearings.

Reduced NPSH Requirements

NPSH requirements describe the minimum pressure required at the suction port in order to keep it from cavitation. Side-channel pumps produce pulse pressure build ups that result in an internal multi-stage effect that lowers potential pump speeds. This is thanks to higher pump heads and slower pump speeds. This increases expected lifespans for these pumps, and also offers greater control over noise.

gravity sewer

While gravity sewer pumps have been a staple of homes and buildings all over the world, they are not necessarily the most effective solution for removing water-waste. They come with their own set of advantages, but when compared to more carefully designed, modern sewage pumps, they do leave a lot to be desired.

Sewage Pumps Save Money

Sewage pumps are designed to be dependable, and works by rejecting materials that are too hard to be broken down. This allows them to work without any undue pressure that may cause them to break-down or become ineffective as time goes on. This means that you will be spending less time and money on maintenance in the long-run.

Sewage Pumps are Environmentally Friendly

The right sewage pump works by reducing the amount of harmful chemicals in sewage water. These compounds, with more traditional gravity systems, will generally find their way into natural eco-systems, contaminating them, water and even food sources, where they can pose a risk to human, animal and plant life.

Installation is Simple

Sewage pumps are compact and designed to be installed with relative ease, even in tight spaces. Furthermore, installing them with the help of a technician (which is advised) is generally inexpensive.

Works with High Sewage Lines

In buildings and homes where high sewage-lines make it impossible for gravity pumps to push water-waste uphill, sewage pumps are actually essential for correct removal of waste products. Even when high sewage-lines are not a problem, sewage pumps allow water to be pumped sustainably and evenly.

submersible pumps

Here at Ernest Electro Engineering we have developed the ultimate in submersible pump solutions, the Simer Submersible Pump.

Simple to use, light-weight and affordable, this solution makes pumping seamless regardless of the application it is being used for. But what is it that makes the Simer such an effective and sought-after solution? Let’s take a closer look:

Automatic and Effective Drainage

The Simer Submersible pump automatically starts pumping when it comes into contact with at least 5mm of water. From there it will continue to do its thing until no more than 2mm are left. This makes it a wholly effective means of moving water, whether it is being expelled or used somewhere else.

Running Water

Applications for the Simer submersible pump vary, making it a great all-round appliance. It is great for carrying water through plumbing where it can be used for washing up, showers, storage and for many other things.

Draining Pools

The process of draining a pool is often an arduous one. It takes plenty of time, is a bit of a hassle, and requires unwavering attention. With the Simer submersible pump, however, draining a pool can be done fairly easily and quickly in comparison to other approaches.

Clearing Floods

Simer submersible pumps are also great for clearing indoor flooded areas such as basements. Here they can be applied to clear an area of water, from where it can either be disposed of or stored for other uses.


There are a number of benefits held by the Simer submersible pump. They are, firstly, lightweight, making them easy to handle and transport when the need arises. They are also easy to operate, making your job of pumping water all the simpler.

Water Pump

When it comes to harnessing the resources around us, doing it in a fast and effective manner ensures that we get the best results and optimum functions for those resources. One way we can harness the resources around is through the use of borehole motors available in Johannesburg.

This is done is through the use of a long cylindrical pipe that is installed into the Earth’s surface. This pipe reaches a section of underground water that can then be used for personal or industrial use. Through the use of electrical water pumps, many methods of extractions can be utilised, all for different purposes. Take a look at what kind of water pumps are available.

Pump it

When it comes to extraction of water in a confined space there are certain factors that come into play; electric water pumps come in all shapes and sizes depending on the task at hand. A Zuwa pump is used mainly for personal use and external threats such as flooding due to rain or a burst pipe.

When an area at home has flooded a room or more, the use of a zuwa pump extracts the water thoroughly, until it is completely dry. If a carpet has been flooded, the use of a suction mat allows all water to be extracted. Through the use of rotating propeller, it causes air to be pulled very quickly from the entrance to the exit thus creating a high volume vortex affect.


When it comes to our personal time on the loo, we do not like speaking about what happens after the whoosh of the leaver. Unfortunately, sometimes it springs up on us when a pipe gives in. luckily through the use of a sewage pump it is just one big slurp and then there is no longer an issue. The sewage pumps work in the same rotary motion as the electrical water pumps, which allows for maximum suction power.
