Imagine staying a day or more without water…i guess you are imagining how hellish is going to be.
This brings us to the fact that man and the entire creation cannot do without water.
For example, to irrigate your garden, top up the swimming pool, to provide household water to a small rural community or farm household or maybe even to service a multi-hectare irrigation scheme brings us to the point where a source of water is needed.
In most cases, that solution is a borehole. But drilling a borehole requires some research and planning, while the cost of a borehole in 2020 is largely dependent on its depth and the amount of casing to be used, the type of rock that will be rill through, the actual ground conditions amongst others.
According to the Borehole Water Association of South Africa, the average drill cost is around R600 a meter, but this can be as much as R900 per meter depending on the company. Yield testing is between R2,000 and R5,000 while the equipment might cost between R20, 000 and R40, 000.
Additional costs might also be required if, for instance, you have to hire a motorized hoist to elevate the hydraulic rig machine into your backyard.
Water Borehole Drilling Process In 4 Steps
The following are the Water Borehole Drilling Process
- Hydro-Geologists Site The Borehole
An expert called a hydro-geologist will look at the land where the borehole will be sited and determine the right location.
This expert ensures you are not drilling into natural hazards or man-made infrastructure such as (pipelines, cables, phone lines, etc).
- Drilling And Construction
After the hydro-geologists must have located the right position, the next process is drilling and construction of the borehole.
Once the borehole has been drilled the necessary unstable lengths of the borehole are steel cased in an effort to reinforce the ‘tube’.
2. Determining The Yield Of The Borehole
Yeah, happy that water is gushing from the borehole, not yet, in order to accurately gauge the yield, an aquifer test will be performed.
Actually, this involves installing a test pump and pumping borehole water for a fixed set of variables; a given time at a given rate, and then assessing the test’s impact on the water level in the borehole.
3. Pumping And Piping The Borehole
After all necessary tests have been passed during drilling and the water certified good for consumption, a piping system will be installed although the nature of the pipe largely depends on the intended use of the borehole water.
Borehole Drilling Prices in South Africa
Water borehole drilling cost depends on many different factors, processes, and components used to drill a borehole.
There are no two boreholes that will be the same, so it is best to work on an average or estimated cost of a borehole.
Factors that Impact Borehole Drilling Cost
- Type of ground
- Depth of the borehole
- The purpose of the borehole
- The machinery, manpower, and materials.
- The type of ground and geology of the site where you want to drill a borehole are the biggest factor that will impact the borehole price.
Here are the estimated costs in South Africa
- Estimated cost for a 30m borehole ±
- Price: R40,500.00 and above.
- Estimated cost for a 60m borehole ± Price: R75,900.00 and above.
- The cheapest so far is R35,600.00 to drill a borehole in South Africa.
Borehole Drilling Cost Per Meter
According to the Water Association of South Africa, the average drill cost is around R600 a meter, but this can be as much as R900 per meter depending on the company.
Borehole Drilling Cost in Limpopo, Pretoria, Capetown, Port Elizabeth, Rustenburg, Mpumalanga.
The average cost of borehole drilling in Limpopo, Pretoria, Capetown, Port Elizabeth, Rustenburg, and Mpumalanga all in South Africa is between R40,500.00 to R123,456.00
Borehole water also known as groundwater provides about 45 percent of global domestic water demands and 75 percent of Africa’s.
In places where Borehole is readily available and of good quality, it can be a reliable resource.
Over the past two decades, Africa has witnessed a significant increase in drilled water wells or boreholes. These are financed by development programs as well as investments by water users and local businesses.
Sustainable Development Goal (SDG) Target 6.1 is to “achieve universal and equitable access to safe and affordable drinking water for all by 2030”. Without doubt, groundwater supplies,
Boreholes in particular, have a tremendous role to play in reaching the SDG target for drinking water.
