Borehole Drilling Prices
Cape Town

The most common question about boreholes is what one costs, and the honest answer is that nobody can tell you a final figure before drilling. Not because contractors are being evasive, but because the cost depends on the depth, and the depth is not known until the hole is finished.

What you can and should understand before you commit is how a borehole is priced - the structure, the separate scopes, and what moves each of them. That is what lets you compare quotes properly, budget realistically and avoid the surprises that come from a single lump-sum figure with no assumptions stated.

How Borehole Drilling Is Priced

Drilling is charged per metre. This is the industry norm across South Africa and it is the fairest structure available, because it means you pay for the hole you actually get rather than for an estimate that could be wrong either way.

A drilling quote typically contains these elements:

Item	How it is usually priced	What to check
Mobilisation and site establishment	A fixed sum to bring the rig and support equipment to site and set up	Whether it is charged separately or included, and whether it changes for difficult access
Drilling	Rate per metre drilled	Whether the rate is flat or changes with depth or formation, and whether hard rock is charged differently
Casing supply and installation	Rate per metre of casing installed	The diameter, material and pressure class quoted - light casing is cheaper and can fail at depth
Screening	Per metre, or per section	Whether slot size is chosen to suit the formation
Gravel pack	Per volume or as a sum, where the formation requires it	Whether it is included at all in unconsolidated ground
Sanitary seal and headworks	Usually a fixed sum	That it is actually included - it is what keeps surface contamination out
Development	Fixed sum, or by the hour	How much time is allowed. Under-developed boreholes underperform permanently
Dry or low-yield outcome	Varies considerably between contractors	Ask explicitly, in writing, before you commit

Because depth is unknown, a drilling quote is a rate card rather than a total. What you can ask for is an expected depth range for your area, so you can budget against a realistic figure - and understand that the final invoice follows the actual metres.

The Scopes That Make Up a Complete Project

Drilling is one line item among several. A borehole that actually delivers water to where you need it involves a sequence of separate scopes, and quotes that cover only some of them are not comparable with quotes that cover more:

1. 1Water survey and siting - geophysical assessment to decide where to drill. Usually a fixed sum.
2. 2Registration - the borehole must be registered with the City, and larger abstraction may require authorisation from the Department of Water and Sanitation. There may be an administrative cost and there will certainly be a time cost.
3. 3Drilling, casing and development - priced per metre as above.
4. 4Yield testing - usually a fixed sum for a defined test programme. Skipping it saves money now and costs more later.
5. 5Water analysis - laboratory cost, varying with how many parameters are analysed.
6. 6Pump and installation - pump, rising main, cable, safety line, headworks and commissioning.
7. 7Electrical work - supply from the distribution board, control gear, protection, trenching and conduit.
8. 8Storage - tank, base or stand, level control, booster pump and pressure vessel where fitted.
9. 9Treatment - specified only after the water analysis, so it cannot be reliably priced upfront.
10. 10Distribution - trenching and pipework to irrigation, the house or other points of use.
11. 11Reinstatement - making good the working area, which is worth confirming rather than assuming.

When comparing two quotes, the first thing to establish is which of these scopes each one actually includes. A cheaper quote is frequently a narrower one.

What Moves the Price Most

Factor	Effect
Depth	The single largest driver. It affects drilling metres, casing metres, cable and rising main length, and the pump size needed to overcome the head. A deeper borehole costs more at every stage, not just at drilling.
Geology	Hard rock drills more slowly than unconsolidated material. Deeply weathered zones need more casing. Unstable formations complicate construction.
Casing specification	Diameter, material and pressure class. Under-specifying casing to save money is a false economy - deformed or collapsed casing is expensive to remedy and sometimes not remediable at all.
Access	Difficult access means more time, sometimes smaller equipment, and occasionally rules a site out entirely. It is worth establishing before anything is quoted.
Yield versus demand	A large gap between what the borehole gives and what you need means storage, a booster pump and level control - a substantial addition to the installation scope.
Water quality	Treatment can range from nothing at all to a multi-stage plant. It is the least predictable item, and it cannot be priced before the water is analysed.
Distance from borehole to point of use	Trenching, pipework and cable runs, plus the friction losses those runs introduce, which can push pump size up.
Electrical supply	Distance to the distribution board, whether a new circuit is needed, and single or three phase.
Property type	A domestic system, a commercial installation with redundancy and an industrial supply with bulk storage and process treatment are very different projects.

How to Compare Borehole Quotes

Quotes that look different are often pricing different things. Work through this list on each one:

• Which scopes are included? Survey, drilling, casing, development, testing, analysis, pump, electrical, storage, treatment, distribution, reinstatement.
• Is drilling priced per metre, and is the rate flat or does it change with depth or formation?
• What casing is specified? Diameter, material and class, and how many metres are allowed for.
• Is development included, and how much time is allowed for it?
• How is a dry or low-yield hole treated? Get this in writing.
• Is yield testing included, and what test programme?
• Is the pump specified, or is it a provisional sum pending the test result? A provisional sum is honest; a specified pump before testing is a warning sign.
• Is treatment included? If it is priced before a water analysis exists, ask on what basis.
• What is excluded? The exclusions list often tells you more than the inclusions.
• What is the payment structure, and what happens if the depth substantially exceeds expectations?
• What documentation will you receive? Formation log, completion details, test report, commissioning readings.
• What warranty applies, to workmanship and to equipment separately?

Budgeting Realistically

A few practical points that make budgeting less stressful:

• Budget against the upper end of the expected depth range, not the lower. If it comes in shallower, you have a pleasant surprise rather than a shortfall.
• Treat treatment as an unknown until the water analysis is done. Set something aside rather than assuming none will be needed.
• Phase the project if cash flow requires it. Drilling, testing and analysis first; installation once you know what you have. This is a sensible sequence anyway, not just a financial one.
• Include the running costs in the picture - electricity, servicing, filter consumables, retesting, and eventual pump replacement.
• Consider the alternative. Where the ground suits it, a wellpoint costs a fraction of a borehole and may be adequate for garden irrigation.
• Do not economise on the parts that are hard to fix. Casing specification, sanitary seal, development and dry-run protection are all cheap at the time and expensive to remedy afterwards.

Where the False Economies Are

Some savings cost more than they save, and they are worth naming:

Tempting saving	What it usually costs later
Skipping the water survey	A higher chance of a poor or dry hole, at a per-metre rate. In hard rock especially, siting is usually cheaper than the drilling it saves.
Skipping yield testing	A pump sized by guesswork, which typically means an oversized pump that runs the borehole down and fails early.
Lighter casing specification	Deformation or collapse at depth, which can be uneconomic to remedy.
Shortened development	A borehole that never reaches its potential yield and produces sand indefinitely.
No dry-run protection	A replacement pump, and often more than one.
No water analysis before treatment	A filtration system that treats something your water does not have, while missing something it does.
Deferring maintenance	An emergency pump replacement instead of a scheduled one, at a worse moment.

This pulls together the indicative ranges from across the site so you can see a whole project in one view. Each row links to the page that explains what drives it. Note how little of a complete project the drilling itself accounts for - that is the point most quotes obscure.

Scope	Indicative range	Notes
Water survey and siting	R5,000 – R12,000	Fixed sum. Higher on farms and large properties.
Drilling, per metre	R500 – R1,200 /m	The headline rate, but rarely half the project.
Casing, installed, per metre	R400 – R700 /m	Quoted per metre alongside drilling. Check the class.
Mobilisation and development	R5,000 – R15,000	Getting the rig in, and developing the hole once drilled.
Yield testing	R3,500 – R15,000	Skipping it is how pumps get sized wrong.
Water analysis	R450 – R3,500	Depends entirely on how many parameters.
Pump, supplied and installed	R15,000 – R45,000	Driven by the duty point, which depth pushes up.
Electrical supply and trenching	R3,000 – R20,000	Distance to the board, single or three phase.
Storage and booster	R12,000 – R35,000	Usually cheaper than a bigger pump, and better for the borehole.
Filtration	R0 – R60,000	The least predictable line. Some properties need nothing.
Servicing, per year	R1,200 – R12,000	Domestic at the low end, commercial at the high.
Complete domestic project	R55,000 – R220,000+	Sandy shallow sites at the bottom, hard-rock Peninsula sites at the top.
Wellpoint alternative	R6,500 – R10,000	Only where sandy ground and a shallow water table allow it.
