Durban South is flat, low ground. Most stands from Clairwood to Isipingo rest on estuarine and alluvial sands, silts and clays laid down by the Umlazi and Mbokodweni rivers, with Karoo shale and sandstone further down. The water table is typically shallow, so water is reached early, but the soft layers need careful casing and screening.
This is the South Durban Industrial Basin, home to refineries, chemical plants, warehouses and the Mobeni and Jacobs factory zones, with older family homes in Merebank, Montclair and Isipingo alongside. That history decides the order of work: we treat water quality as the first question on every job here, before yield or pump size.
What Is Under Durban South
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Estuarine and alluvial sands, silts and clays | The flood plains of the Umlazi and Mbokodweni rivers and the low ground around the old harbour edge | Soft and quick to drill, but loose sand can run into the hole and clay lenses can seal off a promising layer. Screens and gravel packs have to suit the sand grading. |
| Karoo shale and sandstone (Ecca Group) | The bedrock beneath the flats, rising towards the higher ground at Montclair and the Bluff side | A deeper option where the sands are thin or the shallow water tests poorly. Water sits in fractures, so yields are modest and the water can be more mineralised. |
| Dolerite intrusions | Sills and dykes cutting the Karoo rock below the cover | Very hard when fresh, but the fractured contacts beside dolerite are often the best target if a hole has to go into rock. |
Tell us the site, whether it is a home or a business, and what the water must do, and we will price a Durban South borehole with testing included.

- Water is often near the surface in the sandy layers, which makes shallow boreholes and some wellpoints realistic on the flats.
- Quality matters more than quantity because decades of industry in the basin mean shallow water must be tested for hydrocarbons, metals and bacteria before use.
- The sand behaves badly when wet so running sand and clay bands call for proper casing, screens and development rather than an open hole.

What to Watch For Here
Shallow water is the water most exposed to old spills. Refinery, chemical and transport activity around Merebank, Jacobs and Prospecton means the upper aquifer can carry hydrocarbons, solvents or metals. A laboratory test, including hydrocarbons where the site history suggests it, should come before any use beyond basic irrigation, and a deeper sealed hole may be the better design.
Flood plain ground floods. Isipingo and the lower Umbogintwini area took heavy flooding in April 2022. A borehole head on low ground needs a raised, sealed casing top and a sanitary seal so floodwater cannot run straight down the outside of the casing into the aquifer, and control boxes should be mounted well above the ground.
What the Water Is Used For
- Washing trucks, containers and yards at Mobeni and Jacobs depots
- Factory cooling and wash-down water after treatment and testing
- Watering lawns and vegetable gardens on Merebank and Montclair stands
- Standby supply for warehouses during eThekwini water interruptions
- Dust suppression on industrial and logistics sites near Prospecton
Wellpoint or Borehole?
Sometimes, on the sandiest stands. Where the flats are made of clean sand with a shallow water table, a wellpoint can supply garden water cheaply. Clay layers, fine running sand and iron clogging limit many of them, and the shallow water is the most likely to be affected by industrial history, so test it first. For anything beyond garden use, a cased and sealed borehole is the safer choice.
Approval and Abstraction
Durban South falls under eThekwini Metropolitan Municipality. Municipal requirements differ across KwaZulu-Natal. eThekwini is reported to require a borehole to be registered with the municipality once drilling is complete, and its Water By-law prohibits any connection between a borehole system and the municipal supply unless backflow is prevented. Msunduzi, KwaDukuza and Umdoni set their own requirements, so confirm the current position with the municipality before the rig arrives. Separately, the National Water Act governs how much you may abstract: reasonable domestic use generally falls under Schedule 1, and in 2026 the Department of Water and Sanitation confirmed that households using borehole water for reasonable, non-commercial domestic purposes do not need to register nationally. Commercial, agricultural and larger abstraction may need registration or a water use authorisation, and draft national groundwater regulations published for comment in December 2025 may add obligations once finalised. Rules change, so confirm the current position before drilling.

Borehole Prices in This Area
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 | R400 - R950 /m | Soft alluvial sands and silts drill quickly, but running sand and clay layers slow the hole and complicate screening. |
| uPVC casing, installed, per metre | R400 - R700 /m | Unstable alluvium needs casing and screening matched to fine sand, and that material is a real share of the cost here. |
| Mobilisation and site establishment | R2,500 - R8,000 | Industrial yards, security access and working around services move this more than distance. |
| 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 | R45,000 - R150,000+ | 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 - 2026 guides quote per-metre drilling rates for KwaZulu-Natal ranging from about R320/m to R1,500/m, a spread of more than four to one - 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.
Durban South Borehole FAQs
Is borehole water in Durban South safe to use?
Not until it has been tested. The south basin has a long record of refinery, chemical and heavy industrial activity, and shallow groundwater is where any legacy contamination tends to show up. A laboratory analysis covering bacteria, metals, general chemistry and, where the site history warrants it, hydrocarbons is the starting point.
Once the results are in, the water can be matched to a use: irrigation, wash-down, process water after treatment, or drinking water if it passes and is treated. We do not guess at quality here.
Can a factory in Mobeni or Jacobs use borehole water?
Many industrial sites around Durban already use groundwater, and the flats can often supply useful volumes from relatively shallow holes. The main questions are the quality the process needs and how much water will be drawn each day, which shapes the borehole design and the treatment.
Commercial and industrial abstraction usually falls outside Schedule 1, so registration or a water use authorisation with the Department of Water and Sanitation may be needed. We can help you work out where your use is likely to fall.
Why do holes in the flats need screens?
The alluvial sands of the Umlazi and Mbokodweni plains are loose and fine in places. Without a properly slotted screen and a graded gravel pack, sand gets pulled into the pump, wears the impellers and slowly fills the hole.
Developing the borehole after drilling, by surging and pumping until the water runs clear, is part of the job on this ground. Skipping it usually shows up later as a sandy, failing pump.
Does the borehole have to be kept separate from the municipal supply?
Yes. The eThekwini Water By-law does not allow a borehole system to be connected to pipes carrying municipal water unless backflow is properly prevented. In practice the borehole feeds its own tank and its own taps or irrigation lines.
On industrial sites with existing reticulation this needs planning so the two systems never cross. It is easier to design at the start than to separate later.
