Borehole Drilling In Zimbabwe - 5 Things You Need To Know Before Installing A Borehole

Water is an essential need in our daily lives. We drink it, use it for taking baths, for laundry, for cooking, for cleaning, for flushing the toilet, washing your beloved car, and almost every other things. 

No one can deny its importance so it is always a number one priority of every household.

But, if you need extra water to fill in swimming pools, flourishing your beautiful garden, or maybe to service a multi-hectare irrigation plan, then there is nothing better than a borehole that beats a source of cost-effective water where it is needed.

Boreholes: Boreholes are shafts that are drilled into the ground horizontally or vertically. Even though these shafts are narrow, they are very deep. An installed water borehole taps into aquifers or underground stores of water that is created through rain and evaporation in the permeable geological matter.

Boreholes are drilled and lined with a good casing and screen. Just around the screen, an annulus is placed and then packed with rounded inert silica sand or gravel that acts as a filter. To prevent polluted surface water to enter the borehole, a seal near the borehole’s top closes the drill holes in the pipe. After that, a sealed chamber is installed that houses the surface valve and well-head and a stainless steel pump is submerged into the hole.

If you think you might need a borehole at home, there are a few things you need to know first before installing one:

1. Dry Holes: Because this water supply is too deep, drilling contractors cannot guarantee that the borehole will hit the water. Therefore, you shall take a risk and regardless of the result it yields, you will still be responsible for the cost of the borehole.

The potential success of hitting the water would be around 65 to 70% only. However, if you ask a professional water dowser to assist your drillers, then you will have a 90 to 95% success rate. But there is still a risk. If you are lucky, the first drill will be the last one. However, if you are unlucky that day then you might ask for another hole and cause you to pay more.

2. Borehole’s Life: If all equipment is of high quality and the borehole is installed properly without any defect, 20 years of life can be expected for all major components.

3. Noise And Damage: Drilling causes noise pollution which might annoy your neighbours. It is also a messy process so you are advised to give a heads up to your neighbours and ask for their patience. Modern drilling rigs are heavy and very large.

This means that in the process of drilling, even though the contractor has taken reasonable care, unavoidable damages might still occur on your property, particularly in garden areas. In such cases, contractors cannot be held responsible. So you are advised to remove anything of value away from the drilling area or do a complete makeover in cases of damages.

4. Cost Of Borehole’s Installation: Boreholes require a good investment. Get in touch with Nakiso Borehole Drilling to confirm the kind of financial investment you need to make.

5. Borehole Registration: Zimbabwe National Water says groundwater for domestic purposes needs to be registered. 

A borehole adds significant value to your property and it will be a good investment over a period of time. 

So, if you plan to have a borehole at home, choose only experienced borehole drilling companies in order to ensure that you will get most of your risk and expenses.
