Considering there is drought throughout Zimbabwe, owning your own private borehole is a must. It lets you control your own water supply.
Getting your own borehole drilled also means you will have to keep it in good working order if you want to continue receiving water from it. They do require a bit of maintenance to keep them running throughout the years.
The lifespan of a boreholeHow long does a borehole last? This will depend on each specific situation, but usually in the region of around 20 years. It will require maintenance to get it to last this long. The water stored in the aquifers below will change with time (depending how much rainfall your climatic region is getting). The more it rains, the more water will be available to pump up.

Is It a Good Investment?
If you have had your borehole professionally drilled and you are maintaining it well, then when you sell your home it will increase your property value for sure! It’s definitely a great investment for your residential, commercial or industrial property.
How Long Does a Borehole Last?Once your borehole has been drilled, you will pump water up from the aquifers below. Basically, aquifers are created by rainfall and evaporation in the permeable geological matter. It is also important to note that when drilling a borehole in Zimbabwe, you don’t want to pollute that water during the drill. Make sure you use a company that knows what they are doing and don’t use toxic materials. Below are the steps you need to take to start the borehole drilling process:
Hydro-geologists site the area
The Drilling and Construction
Determining the yield
Pumping and piping
Where Does Groundwater Come From?Rainfall in your region is an important part of the cycle. The rainfall received in your area will soak deep into the ground. It passes through layers of soil, rock and gravel. It stops seeping down once the water has reached an area that is completely saturated with water. This is also known as the water table. Reaching the water table will be different for every borehole. Some might be a couple of metres underground, while others could be many meters under.
The Drilling of a BoreholeOnce you have selected the area that you want the borehole to be drilled in, it’s time to actually drill it. Often, people mistakenly think that any hole drilled will result in an endless supply of water. This is not the case. It takes more effort than a simple hole to get water pumping out.
At the end of the pipe, there is a hammer and drill. The hammer and drill will break up bits and pieces of rock and debris from under the ground. This all happens while the pipe is rotating. It’s a messy process.
Residential boreholes in Zimbabwe are often drilled with a 215mm diameter. This will allow a steel casing of around 165mm to be installed down the hole that has just been drilled. In theory, the borehole should be cased in the steel from the top of the hole to the bottom of the hole.
How Much Can You Yield From a Borehole?The only way to find out how much it can produce is to test it. This can be done by means of an aquifer test. The company you have chosen to drill the hole will be able to perform this test for you once the hole has been dug.
The company will have to install a “test pump”. Once the test pump has been installed, they will have to measure how much water comes out the hole for a short period of time.
What Is The Cost of a Borehole?If you are asking yourself the question “how much does a borehole cost?” you must be aware that there is not a standard price for boreholes. The cost of a borehole depends on many factors.
How deep is the actual hole that is being drilled
How much steel casing is used to stabilise it
The type of rocks that need to be drilled through
The ground conditions that need to be drilled through.
You would more than likely expect the drilling of the hole to be easier in soft terrain but that couldn’t be further from the truth. The problem with trying to drill in soft soil is that the hole keeps on collapsing on itself. This happens when the ground is particularly loose.
Difference Between a Wellpoint and a BoreholeHere are a few of the differences between a borehole and a well point. It’s important to understand the differences before getting one of the following installed at your residential or commercial property in Zimbabwe.
Wellpoint – A wellpoint is drilled at a shallower depth. They usually reach between 10m deep and 15m deep. If you are considering getting a well point installed on your property, be aware that they do not produce as much water per day as a borehole. They are perfect for irrigation in smaller residential properties.
Borehole – A borehole is drilled much deeper than a well point. Usually between 30m and 100m in depth. You get much more water per than you do out of a well point. The depth needed to be drilled does affect the cost of a borehole in Zimbabwe. It also takes much longer to drill.
