On an industrial site, water is an input to a process rather than an amenity. That changes the requirements substantially: volumes are larger, quality specifications are set by the process rather than by taste, and an interruption stops production rather than inconveniencing anyone.
Industrial borehole projects are consequently more engineering exercise than purchase. The groundwater resource has to be assessed properly, the abstraction has to be authorised, the water has to meet a defined specification, and the system needs to keep running when a component fails.
Know your process demand and quality specification? That is where an industrial assessment starts.
Get an Industrial Borehole QuoteWhere Industrial Boreholes Are Used
- Cooling water for plant and equipment, where volumes are large and quality requirements centre on hardness and fouling
- Process water where the specification is set by the product or process rather than by drinking water standards
- Washdown and cleaning in food, beverage and manufacturing facilities, where quality requirements can be high
- Boiler feed, where hardness and dissolved solids matter a great deal and treatment is essential
- Fire water storage, where the borehole maintains a reserve rather than supplying directly
- Dust suppression on yards, hardstanding and material handling areas
- Landscaping and grounds on larger industrial sites
- Vehicle and fleet washing at depots and distribution facilities
Different uses on the same site often justify different treatment. Water suitable for dust suppression needs nothing like the treatment required for boiler feed, and treating everything to the highest standard on site is an expensive mistake.
Volume Changes the Approach
Higher abstraction rates shift several things at once:
| Aspect | How it differs at industrial volumes |
|---|---|
| Resource assessment | A single-property survey may not be sufficient. Sustained high abstraction needs an assessment of what the aquifer can support over time, not just what one borehole can produce on a test day. |
| Regulatory position | Abstraction at industrial volumes is very likely to require registration and a water use authorisation from the Department of Water and Sanitation, with monitoring and reporting obligations attached. |
| Borehole construction | Larger diameters to accept larger pumps and higher flows, with casing and screen specified for the duty rather than to a domestic standard. |
| Testing | Extended constant-rate testing to establish long-term sustainable abstraction, since a short test can overstate what a borehole will support continuously. |
| Number of boreholes | Demand is frequently met by more than one borehole, both to spread abstraction across the aquifer and to provide redundancy. |
| Storage | Bulk storage sized against process demand and required continuity, which is usually a substantial installation in its own right. |
| Monitoring | Flow metering and water level monitoring become operational requirements rather than good practice, and are often a condition of authorisation. |
Sustainable abstraction is the binding constraint, not pump capacity. It is entirely possible to install a pump that extracts more than the aquifer can support. Doing so draws water levels down over months, degrades the borehole, may affect neighbouring users, and eventually fails. Industrial abstraction has to be planned against what the resource sustains over years, which is why the assessment work matters more here than anywhere else.
Process Water Quality
Industrial quality requirements are set by the application, and they are sometimes stricter than drinking water standards in specific respects while being irrelevant in others:
- Hardness - critical for boilers, cooling systems and heat exchangers, where scaling reduces efficiency and causes damage
- Iron and manganese - staining matters where the product or packaging is affected, and both foul equipment and membranes
- Total dissolved solids and conductivity - significant for many processes and for corrosion
- Chloride and sulphate - corrosion risk to plant and pipework
- Silica - a specific concern in boiler and cooling applications
- Suspended solids - equipment protection and process consistency
- Microbiological - critical in food and beverage applications, and for cooling systems where biological growth is a risk
- Temperature and pH - process-dependent, and relevant to how treatment performs
Establish the specification the process requires before designing treatment, then analyse the raw water against it. The gap between the two defines the treatment plant. Working the other way round - installing treatment and then checking whether it suits - is how expensive equipment ends up doing the wrong job.
Multiple uses with different quality needs? Treating each stream to its own standard usually costs less.
Request an Industrial Water AssessmentRedundancy and Continuity
Where water is a production input, single points of failure need to be identified and addressed deliberately:
- 1Establish the cost of an interruption per hour or per shift. This sets the budget for redundancy and makes the decisions straightforward.
- 2Identify the single points of failure - one borehole, one pump, one power supply, one treatment train, one control system.
- 3Decide the acceptable outage for each critical use, which may differ across the site.
- 4Size storage to cover that outage, so a failure becomes a maintenance event rather than a production stoppage.
- 5Consider duty and standby pumps, which allow servicing without shutdown as well as covering failure.
- 6Plan for power failure, including whether pumping is on backup generation and whether stored water can be drawn without power.
- 7Retain the municipal connection where available as a backup source rather than disconnecting it.
- 8Hold critical spares - the lead time on a large submersible pump is not something to discover during an outage.
Monitoring and Compliance
Industrial abstraction generally carries obligations, and the monitoring that satisfies them is also what protects the asset:
- Flow metering on abstraction, recorded rather than estimated
- Water level monitoring, both standing and pumping, tracked over time to detect drawdown trends
- Periodic water quality analysis, both for process control and for any conditions attached to authorisation
- Abstraction records kept in the form required by the authorisation
- Pump performance records - running hours, current, flow and pressure
- Treatment plant monitoring, including consumables, backwash volumes and treated water quality
Trend data is what makes this valuable beyond compliance. A gradual increase in drawdown at the same abstraction rate is an early warning that either the borehole is deteriorating or the resource is under pressure, and both are far cheaper to address early.

What an Industrial Borehole Costs
Industrial projects are engineering exercises and price accordingly. The largest variables are how many boreholes the demand requires, the treatment train the process specification demands, and the redundancy the cost of downtime justifies.
| Scenario | Indicative total | What is included and what moves it |
|---|---|---|
| Resource assessment and authorisation support | R25,000 – R120,000 | Hydrogeological assessment, extended testing, and the DWS water use authorisation process. |
| Single high-yield borehole, drilled and equipped | R180,000 – R450,000 | Larger diameter, heavier casing, larger pump and three-phase supply. |
| Multi-borehole wellfield | R450,000 – R1,500,000+ | Common where demand exceeds what one borehole sustains. Spreads abstraction and provides redundancy. |
| Bulk storage installation | R80,000 – R400,000+ | Sized against the acceptable outage rather than daily consumption. |
| Process water treatment plant | R60,000 – R600,000+ | Entirely dependent on the specification. Boiler feed and food-grade sit at the top end. |
| Metering, monitoring and reporting systems | R15,000 – R80,000 | Usually a condition of authorisation rather than optional. |
| Planned maintenance contract, per year | R15,000 – R70,000 | Running hours, number of boreholes and treatment complexity. |
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.
Industrial Borehole FAQs
Do we need a water licence for an industrial borehole?
Very likely. Abstraction at industrial volumes goes well beyond the reasonable domestic use covered by Schedule 1 of the National Water Act, so registration and a water use authorisation from the Department of Water and Sanitation are usually required.
Authorisations typically carry conditions around abstraction limits, metering, monitoring and reporting. The borehole must also be registered with the City. Establish the regulatory position early, because it affects both the programme and the design.
Can one borehole supply a factory?
It depends entirely on the volume required against what the borehole sustains, and industrial demand often exceeds what a single borehole supports on a continuous basis. Multiple boreholes are common, both to spread abstraction across the aquifer and to provide redundancy.
The constraint is sustainable abstraction rather than pump capacity. Installing a larger pump on a single borehole to meet demand it cannot sustain draws levels down over months and degrades the borehole.
What water quality is needed for industrial processes?
Whatever the process specifies, which varies enormously and is sometimes stricter than drinking water standards in particular respects. Boiler feed and cooling applications are sensitive to hardness, silica and dissolved solids; food and beverage applications set high microbiological standards; dust suppression needs very little.
Define the specification for each use first, then analyse the raw water against it. The gap between the two defines the treatment plant.
How do we ensure supply continuity if the pump fails?
Through a combination of storage, redundancy and spares, sized against the cost of an interruption. Storage that covers your acceptable outage turns a pump failure into a maintenance event rather than a production stoppage.
Duty and standby pump arrangements allow servicing without shutdown as well as covering failure. Retaining the municipal connection as backup and holding critical spares are both worth doing - the lead time on a large submersible pump is not something to discover during an outage.
How is sustainable abstraction determined for high-volume use?
By extended constant-rate testing rather than a short test, because a borehole can produce well above its sustainable rate for a limited period. The test needs to run long enough for the drawdown trend to stabilise and for recovery behaviour to be assessed.
At industrial volumes this often extends to assessing what the aquifer supports across the area rather than what one borehole produces in isolation, particularly where other abstractors are nearby.
Can borehole water be used for boiler feed?
Only with appropriate treatment, and the requirements are demanding. Boilers are sensitive to hardness, dissolved solids and silica, all of which cause scaling that reduces efficiency and can damage equipment.
That usually means a treatment train rather than a single filter - typically softening and often membrane treatment, with ongoing monitoring of treated water quality. Get the raw water analysed against the boiler specification before designing anything.
What monitoring is required on an industrial borehole?
Flow metering on abstraction and water level monitoring are the core requirements, usually recorded rather than estimated. Periodic water quality analysis is needed both for process control and for any conditions attached to a water use authorisation.
Beyond compliance, the trend data is what protects the asset. A gradual increase in drawdown at the same abstraction rate warns you that either the borehole is deteriorating or the resource is under pressure, well before either becomes a crisis.
How long does an industrial borehole project take?
Considerably longer than a domestic or small commercial one. Resource assessment, regulatory authorisation, drilling, extended testing, treatment design and installation of bulk storage each take time, and several depend on the one before.
Regulatory authorisation in particular can be the critical path item, so it is worth establishing the requirements at the outset rather than partway through. Plan the project in months, with the assessment and authorisation work started early.
