Borehole Camera Inspections: What They Reveal and Cost

If your borehole has slowed to a trickle, started pumping sandy water, or simply stopped working, guesswork is expensive. Before any contractor replaces a pump or recommends full rehabilitation, a downhole camera inspection gives you actual evidence of what is happening below ground — and stops you paying for fixes that will not solve the real problem.

What a borehole camera inspection actually is

A downhole camera is a waterproof, cylindrical unit — typically 40–60 mm in diameter — attached to a reinforced cable with a depth counter. The operator lowers it slowly into the borehole while watching a live feed on a surface monitor. Good operators record the entire descent so you receive a copy of the footage. The camera captures the full length of the casing, any screen sections, the water column, and the position of the pump.

Most cameras used in Johannesburg work to depths of 200–300 m, which covers the majority of residential and smallholding boreholes in the area. If your borehole is unusually deep, confirm the contractor’s equipment specification before booking.

What the camera typically reveals

This is where the inspection earns its cost. Common findings include:

• Casing damage or collapse. PVC or steel casing can crack, deform, or partially collapse — particularly in older boreholes or where ground movement has occurred. A collapsed section explains reduced yield and can trap a pump permanently if not caught in time.
• Sediment and biofouling build-up. Iron bacteria and calcium deposits accumulate on the casing walls and screens over years. The camera shows how severe the build-up is and whether jetting or chemical treatment is realistic.
• Incorrect pump depth. A pump sitting below the water table’s lowest seasonal point, or resting on the bottom of the borehole, causes both mechanical damage and sand ingestion. The camera confirms the pump’s exact position relative to the casing joints and water level.
• Screen condition. Slotted screens allow water in while excluding sediment. A camera shows whether screens are intact, corroded, or blocked — information you cannot get from surface tests alone.
• Casing joint misalignment. Joints that have shifted over time create snag points that can make future pump extraction extremely difficult.
• Water entry points. The camera often shows where water enters the borehole — useful for understanding yield limitations and planning rehabilitation.

For homeowners dealing with repeated pump failures or declining yield, this footage is the difference between targeted repairs and throwing money at the wrong problem. If you are also dealing with an existing pump issue, the repair process is covered in more detail on our borehole repairs Johannesburg post.

What a borehole camera inspection costs in Johannesburg

As a rough guide, expect to pay R3,000–R8,000 for a camera inspection in the Johannesburg area. The price range reflects a few variables:

Factor	Lower end	Higher end
Borehole depth	Shallow (under 60 m)	Deep (150 m+)
Footage included	Verbal report only	Full digital recording + written report
Mobilisation	Contractor already nearby	Long travel distance
Pump removal needed	Pump already out	Pump must be pulled first

Note that if the pump needs to be pulled before the camera can descend, that is typically a separate charge — pump extraction commonly adds R2,000–R5,000 depending on depth and whether the pump is stuck. Confirm this with any contractor before you book.

Always ask for a written report, not just verbal feedback on the day. A written report documents the findings you can then share with a second contractor or use to support an insurance claim.

Getting quotes from several contractors is the most reliable way to check whether an inspection price is reasonable for your borehole's depth and location. Compare 3 free quotes — vetted installers, no obligation.

When to get a camera inspection — and when you don’t need one

A camera inspection is worth the cost when:

• Yield has dropped significantly and you cannot explain why.
• The pump has failed more than once in a short period.
• You are buying a property with an existing borehole and want to understand its condition.
• A contractor is recommending expensive rehabilitation and you want independent evidence before committing.
• The pump cannot be extracted and you suspect a casing obstruction.

You probably do not need an inspection if the borehole is newly drilled and functioning well, or if a simple electrical fault has already been identified as the cause of pump failure. A camera is a diagnostic tool — use it when the diagnosis is genuinely unclear.

For newer installations or if you are still weighing whether to drill at all, our borehole drilling guide covers the full process from site assessment through to commissioning.

How to choose a camera inspection contractor

Not every borehole contractor owns camera equipment — many subcontract the work. That is not necessarily a problem, but know who is actually doing the inspection. Questions worth asking:

• What is the camera’s maximum depth rating?
• Do I receive a digital recording of the full descent?
• Will the report include still images at key problem points?
• Is pump extraction included or charged separately?
• Are you registered with the relevant provincial groundwater authority?

In Gauteng, borehole contractors should be able to demonstrate compliance with the National Water Act and relevant Department of Water and Sanitation requirements. If you want to understand how to compare quotes across multiple contractors — not just on price — the process is explained in our piece on how to compare water quotes.

What happens after the inspection

The camera footage gives you a clear decision tree:

• Minor sediment or biofouling → borehole jetting or chemical rehabilitation, typically lower cost.
• Pump in wrong position → pump reposition, which is straightforward if the casing is intact.
• Moderate casing damage → assess whether steel liner insertion is cost-effective versus the borehole’s remaining yield.
• Severe casing collapse or casing fully blocked → in some cases, the borehole is beyond economic repair. That is a hard finding, but knowing it early saves you from spending further money on a lost cause.
• No structural problems found → attention shifts to above-ground components: pressure tanks, pipework, controls.

The inspection does not make those decisions for you, but it gives you the evidence to make them yourself — or to have an informed conversation with any contractor quoting on the work.

If the inspection has flagged a repair or rehabilitation job, getting multiple quotes is straightforward and free. Get repair quotes from vetted contractors — no obligation.

The bottom line

A borehole camera inspection is a relatively modest outlay — typically R3,000–R8,000 — against the R15,000–R35,000 cost of pump replacement or the R60,000–R100,000 range typical for a complete new borehole system in Johannesburg. If your borehole is underperforming and the cause is not obvious, spending on a proper diagnosis before committing to any repair is almost always the more sensible sequence. Always insist on a written report with footage, and get at least two quotes on any rehabilitation work the inspection recommends.
