Waterfall sits in the Upper Highway area between Hillcrest and Kloof, on tillite and Natal Group ground with large stands and smallholdings.
Hard drilling, fracture-dependent yields, and enough space on most properties to site a hole properly.
What Is Under Waterfall
The formations below are what a rig actually meets on a Waterfall 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 |
|---|---|---|
| Dwyka Group tillite | The dominant formation beneath much of the Upper Highway area | Hard, massive and a genuinely poor aquifer. Water comes from fracturing and weathering rather than from the rock itself, and yields are frequently low. |
| Natal Group sandstone | Where it survives above the tillite on the higher ground | A better prospect than the tillite, fractured and moderately productive where present. |
| Basement granite and gneiss | Beneath the sequence | Water in the weathered mantle and in jointing. Depth to fresh rock varies considerably across the area. |

Get a Waterfall Borehole QuoteWhat That Means for Your Borehole
- This is the hardest ground in the Durban area to get a good yield from, and honest contractors say so before drilling rather than after.
- Structure is everything. Fracture zones, dykes and contacts carry what water there is. The tillite between them carries very little.
- A survey is worth more here than almost anywhere, because the cost of a poorly sited hole on tillite is high and the odds without siting are poor.
Where We Work Around Waterfall
- Waterfall central and the village
- Kloof and Hillcrest boundaries
- Assagay and Botha's Hill approaches
- Everton side
- Smallholdings and agricultural properties
- Larger residential stands
What to Watch For Here
Smallholdings here carry stock and irrigation demand, which changes both the sizing and the storage arrangement.
Tillite is the cost driver, and a quote should be explicit about how hard ground is handled.
What the Water Is Used For
- Stock watering and animal supply
- Orchard, vegetable and pasture irrigation
- Stable, shed and equipment washdown
- Household supply where the analysis allows it
- Fire water and standby storage
Wellpoint or Borehole?
Not viable. Dwyka tillite near surface gives a driven point nothing to work with, and there is no shallow sand aquifer across most of the area.
Water Quality in Waterfall
Where a hole on this ground does produce, the water is usually good quality and moderately hard. Iron appears regularly. The constraint here is quantity rather than quality, which is the reverse of the coastal picture.
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
eThekwini requires boreholes to be registered with eThekwini Water and Sanitation, and prohibits any cross-connection between borehole water and the municipal supply. The National Water Act governs how much you may abstract: reasonable domestic use generally falls under Schedule 1, while irrigation or commercial volumes 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 Waterfall, KZN
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 | R500 - R1,200 /m | Tillite is hard, slow drilling, and a second position is needed more often here than elsewhere. |
| uPVC casing, installed, per metre | R400 - R750 /m | The weathered zone above fresh rock needs casing; its thickness varies with position. |
| Mobilisation and site establishment | R3,000 - R10,000 | 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 | R80,000 - R210,000+ | 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.
Waterfall, KZN Borehole FAQs
Can a Waterfall smallholding run on a borehole?
Frequently, for stock watering and irrigation. Sizing depends on the tested sustainable yield rather than on what you would like the hole to deliver.
Storage does a lot of work on a smallholding. A tank turns a moderate yield into a usable daily volume.
Is this the same Waterfall as the one in Midrand?
No. This is Waterfall in the KwaZulu-Natal Upper Highway area, between Hillcrest and Kloof.
The ground could hardly be more different: granite in Midrand, tillite and sandstone here.
Is it worth drilling a borehole in Waterfall at all?
It can be, but this is ground where the honest answer is sometimes no. Dwyka tillite is a poor aquifer and low-yielding or dry holes are more common here than in most of the Durban area.
A geophysical survey materially changes the odds, and a contractor who quotes a job on this ground without discussing that risk with you is not being straight about it.
Why are yields so low in Waterfall?
Because tillite has almost no primary porosity. It does not hold water in the rock mass the way a sandstone or a sand aquifer does, so everything depends on intersecting a fracture zone or a contact.
Where a hole does find structure, the water is usually good. The difficulty is finding it, which is precisely what siting is for.
