Addo sits in the Sundays River valley on Uitenhage Group ground, with the Kirkwood and Sundays River Formations beneath the citrus.
This is irrigation country, so the sizing exercise is about sustained volume rather than a garden peak.
What Is Under Addo
The formations below are what a rig actually meets on a Addo 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 |
|---|---|---|
| Alexandria and Nanaga Formations | The coastal terraces and palaeodunes from Alexandria to Port Alfred | Semi-consolidated to consolidated calcareous sandstone, coquinite and aeolianite with calcrete. Intergranular and fracture flow combined, and the basal conglomerate yields only low to fair quantities. |
| Kirkwood and Sundays River Formations | The Sundays River valley through Kirkwood and Addo | Reddish mudstone and impermeable mudstone with sandstone lenses. Acts largely as an aquiclude, and the water in it is frequently salty. |
| Schelm Hoek dune sand and estuarine sand | The dune cordon and the river mouths at Port Alfred, Kenton and Boknes | Genuinely unconsolidated and shallow, which makes it the one wellpoint target here. Brackish more often than not. |

- Brackish is the normal result on this coast, not the exception, and it is why Kenton, Bushman's and Alexandria all run on reverse osmosis rather than on borehole water alone. Plan around treatment or around non-potable use.
- The deeper Table Mountain Group is the good water, and in the Sundays River valley it supports substantial citrus and lucerne irrigation. That is a deeper and more expensive hole than one stopping in the Uitenhage Group.
- Calcareous ground means hardness, because limestone, coquina and calcrete all contribute. It is manageable, but it belongs in the budget for fittings and treatment.

What to Watch For Here
The shallow Uitenhage Group beds are frequently brackish, and a hole that stops in them can yield reasonably and still give water you cannot use. The good water in this valley is the deeper Table Mountain Group, which supports the citrus and lucerne irrigation here.
Citrus irrigation is a sustained, year-round draw, so the tested sustainable yield matters far more than a peak figure, and storage is part of the design rather than an add-on.
What the Water Is Used For
- Crop, vineyard and orchard irrigation
- Stock watering across camps
- Packhouse, cellar and equipment washdown
- Frost protection and establishment watering
- Household and worker housing supply
Wellpoint or Borehole?
Only on the dune cordon and the estuarine sand at the river mouths, and the water there is commonly brackish. The Alexandria, Nanaga and Bathurst Formations are consolidated and cannot take a driven point, which is worth saying plainly because they look like sand.
Water Quality in Addo
Brackish water is the defining local issue. Uitenhage Group boreholes are generally unsuitable for domestic or irrigation use without treatment, and the Sundays River Formation carries very salty, probably connate water. Hardness is predictable in the calcareous Algoa Group. On cultivated ground, nitrate from fertiliser belongs on the analysis.
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
Groundwater itself is regulated nationally rather than municipally, and we could not find a published borehole by-law for this district municipality. As the water services authority it can still require approval before a property draws on an alternative supply, so we confirm the local position before drilling rather than assuming it. Separately, the National Water Act governs how much you may abstract. Reasonable domestic use and small-scale garden watering generally fall under Schedule 1 and need no licence or registration, but taking more than 10 cubic metres a day from groundwater on a property must be registered, and irrigation or commercial volumes usually require registration or a water use authorisation from the Department of Water and Sanitation.

Borehole Prices in Addo
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 | R450 - R1,000 /m | Shallow coastal and Uitenhage Group holes drill quickly. A deeper hole targeting the Table Mountain Group is a different cost altogether. |
| uPVC casing, installed, per metre | R420 - R780 /m | Screening and gravel pack through semi-consolidated sand, and casing through the weathered mudstone section. |
| Mobilisation and site establishment | R2,500 - R11,000 | Access, distance 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 | R65,000 - R180,000+ | 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.
Addo Borehole FAQs
Can a borehole irrigate citrus at Addo?
It can contribute, and many properties here run a combination of river allocation and groundwater. Whether it can carry a block on its own depends entirely on the tested yield.
Sizing against an untested yield is the most expensive mistake in agricultural drilling, because the pump and the planting both get specified around a number that was never real.
Do I need a water licence to irrigate from a borehole here?
Very likely, once volumes go beyond reasonable domestic use. The National Water Act governs abstraction and irrigation quantities generally require registration or authorisation from the Department of Water and Sanitation.
In an established irrigation valley this is worth confirming before drilling, not after the pump is in.
Will borehole water at Addo be salty?
Frequently, yes, and it is worth hearing that before you drill rather than after. This coast is dominated by brackish groundwater, which is precisely why the local municipal schemes depend on reverse osmosis.
That does not make a borehole pointless. It makes the water analysis the step that decides what you can use it for, and it often means irrigation and washdown rather than drinking.
Can a Addo property irrigate from a borehole?
It depends entirely on the analysis, because salinity and sodium matter more to soil structure and to trees than they do to a lawn.
The deeper Table Mountain Group water in the Sundays River valley does support large citrus and lucerne irrigation, so good water exists here. It is usually deeper than people expect.
