Borehole Maintenance

Boreholes should not just be drilled and forgotten. They also need to be kept in good shape and maintenance. Borehole maintenance does not have to be something serious and massive. Just some simple things can keep your borehole in good shape and condition for years and years.

What Is Casing A Borehole and How Does Borehole Casing Work In Zimbabwe?

Once a borehole has been drilled, if it is to become a productive borehole, the borehole must undergo completion. 

While drilling borehole cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the borehole cannot support themselves. 

Similar to the bones of your spine protecting the spinal cord, the casing is tubing that is set inside the drilled well to protect and support the borehole stream.

In addition to providing stabilization and keeping the sides of the borehole from caving in on themselves, casing protects the borehole stream from outside contaminants, as well as any freshwater reservoirs from the oil or gas that is being produced.

Also known as setting pipe, casing a well involves running PVC pipes down the inside of a recently drilled borehole. The small space between the casing and the untreated sides of the borehole is filled with gravel pack and cement to permanently set the casing in place.

Casing A Borehole: Nakiso Borehole Drilling installs PVC borehole casings and screen pipes in two main sizes 140mm and 180mm in pressure classes, PN 6, PN 9 and PN 10. PVC Borehole casing are widely used because it is light, strong, easy to install, durable, corrosion-resistant and relatively inexpensive.

The choice of any material depends upon its strengths and weaknesses in relation to the particular intended use. Conditions at a Borehole Drilling site, and within a borehole, are generally aggressive. PVC casing and screen is easily able to withstand most conditions, but it is important for a driller, engineer or hydrogeologist to be aware of conditions or circumstances that might prejudice the integrity of the PVC and consequently the borehole. 

PVC is plastic. It has a low compressive and tensile strength relative to steel. It can be softened by heat, deformed by sudden or gradual stress and shattered by strong impacts. 

Generally, the PVC casing is stronger than the PVC screen, and the thick-walled PVC casing is stronger than the thin-walled casing. 

PVC is much more flexible than steel, therefore it should be supported, both on the ground, and in the borehole.

Determining The Strength Of PVC Borehole Casing: The strength of PVC casing is often described as collapse resistance. The strength, or collapse resistance, depends upon both the thickness of the wall of the casing and the diameter of the casing. A narrow diameter casing is stronger than a wide diameter casing with the same wall thickness. 

It is more difficult to deform a narrow diameter casing.
Narrow diameter casing usually maintains a perfectly circular circumference profile.

Borehole Flushing In Zimbabwe - What Causes Borehole Siltation and Why You Need To Flush Your Borehole!

At Nakiso Borehole Drilling we once completed an interesting project where initially our client suspected that the aquifer was running dry, as the borehole output had dropped off and the pump was sucking air. 

Due to the location of the site and knowledge of the ground conditions, we suspected that the fault was more than likely due to the PVC bore screen having become blocked and silted up.

So once our client had contacted us, with our Operation Manager's vast knowledge of hands-on engineering skills, he devised a method to desilt the bore and clean the bore screen section. As soon as our engineers arrived on site they immediately realised that our suspicions were, in fact, correct, as all around the borehole entrance and surrounding area was a fine film of silt. 

We flushed the Borehole and within a short period of time, it was obvious that our plan was going to be successful, as we had removed quite a large volume of silt from the borehole increasing the yield. 

The more silt we removed the greater the yield.

Once this process was completed a new pump was installed and the bore test pump. Our client was ecstatic as they had started to consider that it was going to be necessary to drill a new borehole water supply.

If you are experiencing similar problems then contact us for further advice, we would be more than happy to offer our services.

Borehole Flushing: Borehole Flushing is needed when the pores of the aquifer inside the borehole get clogged by slit and sand-sized particles or mineral deposits reducing the permeability of the aquifer making it difficult to pump water, thus reducing the water yield. 

This can happen over the course after prolonged usage of a borehole for years or it can happen quickly after just a couple of years depending upon a variety of factors. 

These particles that deter the water flow, may reduce the water yield, change its odour, colour, or even taste and hence must be removed as soon as possible to improve the water yield and quality. And this is where our Borehole Flushing Services in Zimbabwe come in.

We can help you accomplish this quickly and efficiently at an affordable price point.

At Nakiso Borehole Drilling, we use high-pressure water injection procedures with advanced air compressors and flushing tools. Compressed air is passed into the borehole clearing out all the silt and sand, raw dust, decayed particles, mineral deposits, and other extraneous particles that are causing the borehole to clog. 

The borehole flushing process is continued until all the particles are cleared and a clean stream of water is pumped out of the borehole. After a borehole is thoroughly flushed you can enjoy a clean and boosted water yield that continues for years.
