Borehole Installers Gauteng | Drilling, Pumps & Testing

Gauteng is hard-rock country, and the formation under your suburb decides the depth, the risk and the water quality far more than the province does.

Granite in the north, Witwatersrand quartzite through the centre, dolomite on two belts and Pretoria Group rocks in the capital: four different drilling propositions in one province.

What Is Under Gauteng

The formations below are what a rig actually meets on a Gauteng property, and between them they govern the depth, the casing requirement and what the hole will realistically give you.

Formation	Where it sits	What it means for drilling
Halfway House Granite	The northern suburbs of Johannesburg, Midrand and Sandton	Water in the weathered mantle and in dyke contacts and fracture zones. Depth to fresh rock varies considerably across short distances.
Witwatersrand Supergroup quartzite and shale	The central ridges through Johannesburg, the West Rand and the southern suburbs	Hard, fracture-dependent and moderately productive where a structure is intersected. Mining legacy makes water quality testing important.
Malmani Subgroup dolomite	Centurion, the West Rand and parts of the Far East Rand	Capable of very high yields, and the most stability-sensitive ground in the province. Site assessment comes before drilling.
Pretoria Group quartzite and shale with diabase	Pretoria and its eastern suburbs	Contact zones between diabase and the host rock are the targets. Moderate yields, good water quality.

What That Means for Your Borehole

Gauteng has no single aquifer, and the formation under your suburb changes the depth, the cost, the risk and the water quality.
Structure-targeted siting matters across almost all of it, because hard-rock provinces hold water in fractures rather than in the rock mass.
Dolomite and mining legacy are the two province-specific risks, and which one applies to you depends entirely on where you are.

What to Watch For Here

Dolomite and mining legacy are the two province-specific risks. Which of them applies to you depends entirely on where you are, and a contractor who does not raise the relevant one is not paying attention.

There is no shallow sand aquifer anywhere in Gauteng. Wellpoints are effectively not an option here, which is a difference from the coastal provinces worth knowing before you start comparing costs.

What the Water Is Used For

Irrigating established gardens and mature trees
Topping up the pool, subject to what the analysis says
Washing paving, vehicles and hard surfaces
Standby supply when municipal water is interrupted
Reducing a monthly municipal water bill

Wellpoint or Borehole?

Generally not viable anywhere in Gauteng. The province has no widespread shallow sand aquifer of the kind a driven wellpoint needs, so a drilled borehole is effectively the only route.

Water Quality in Gauteng

It varies by formation. Dolomitic water is hard; granite and quartzite water is moderately mineralised and generally good; mining-affected areas can carry elevated sulphate, iron and metals. A laboratory analysis of the actual hole is the only thing that settles it.

A water analysis is what turns that from a general expectation into a number for your specific hole, and treatment should be specified against the result rather than against the area's reputation.

Registration and Abstraction

Johannesburg Water's by-laws require boreholes to be registered with the City, and prohibit any physical connection between a borehole system and the municipal reticulation. The National Water Act sits above that: reasonable domestic use generally falls under Schedule 1, while irrigation or commercial abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. Requirements change, so confirm your position before drilling.

Borehole Prices in Gauteng

Drilling is charged per metre, so depth drives the total. The ranges below are framed for local ground conditions and access.

Item	Indicative range	What moves it locally
Drilling, per metre	R450 - R1,200 /m	Hard rock throughout the province. Dolomite protocol and difficult access push the upper end.
uPVC casing, installed, per metre	R400 - R850 /m	Thick weathered mantles are common, and on dolomite casing and sealing is a stability requirement.
Mobilisation and site establishment	R2,500 - R12,000	Access and site conditions move this; a site visit settles it before quoting.
Water survey	R5,000 - R12,000	Targets structure rather than depth. Worth most where yield is fracture-dependent.
Yield testing	R3,500 - R15,000	Establishes the sustainable rate that pump selection depends on.
Pump, supplied and installed	R15,000 - R45,000	Greater depth means more head, which means a larger pump and heavier cable.
Storage and booster	R12,000 - R35,000	Needed wherever peak demand exceeds the borehole's sustainable rate.
Typical complete project	R70,000 - R240,000+	Everything above, excluding treatment, which depends entirely on the water analysis.

These are indicative ranges, not a quotation. They are compiled from published South African supplier and contractor pricing to give you a starting point for budgeting. They are not our rate card, and no figure here is a commitment.

Treat them as a broad guide only. Published borehole pricing in South Africa varies enormously - different 2026 guides quote per-metre drilling rates for the same province that differ by a factor of three - because depth, geology, access, specification, distance and fuel costs all move the number. Depth in particular is not known until the hole is finished. Figures generally exclude VAT unless noted, and change over time. Only an itemised written quote against your actual site means anything.

Gauteng Borehole FAQs

Is borehole water common in Gauteng?

Increasingly so, driven by water supply interruptions, tariff increases and the reliability problems in parts of the province's reticulation.

Ground conditions support it in most areas, but the yields are moderate rather than generous and the systems that work are the ones designed around storage.

Do I need permission to drill in Gauteng?

Municipal registration requirements apply across the metros, and the by-laws in Johannesburg, Tshwane and Ekurhuleni all prohibit any physical cross-connection between borehole water and the municipal supply.

The National Water Act governs abstraction separately. Confirm both positions with your own municipality before drilling rather than after.

Is groundwater available everywhere in Gauteng?

Not uniformly. Gauteng is hard-rock country where water sits in fractures, dyke contacts and, on the dolomite belts, solution cavities. Some suburbs are consistently productive and others are not.

That variability is exactly why siting and a realistic per-metre quote matter more here than a headline project price.

What is the biggest risk when drilling in Gauteng?

It depends where you are. On the dolomite belts through Centurion and the West Rand, ground stability is the first concern and a site assessment precedes drilling. Across the mining basin, water quality is.

Neither rules out a borehole. Both change how the project should be approached, and a contractor who does not raise the relevant one is not paying attention.
