North Riding is on the western side of the granite dome. Typical profiles show weathered granite near surface, which needs casing, over firmer rock in which fractures and quartz veins carry most of the groundwater.
The suburb mixes high density complexes and townhouses along its main routes with freestanding homes and, toward the north, the larger plots of Northriding Agricultural Holdings where there is far more room to work.
What Is Under North Riding
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Halfway House granite and gneiss | The basement across the northern and western edge of the Johannesburg Dome | Hard and slow once fresh. Water sits in joints and fracture zones, so siting matters more than depth. |
| Thick weathered granite | The upper section, often deeper on the gentle open ground of the outer dome | Fast, unstable drilling that must be cased. A deeper weathered zone can store more water at its base. |
| Dyke lines and spruit-aligned fractures | Along the Jukskei and its tributaries and across the open ground | The broken ground beside these features is where yields improve, and it is what a survey traces. |

- Open ground gives more siting options which makes a survey easier to act on than on a tight suburban stand.
- Yields are typically moderate so storage sized for peak days is usually part of the design.
- Water quality is usually good but livestock, septic systems and fertiliser use are worth keeping away from the headworks.

What to Watch For Here
Old septic tanks on holdings deserve attention. Many agricultural holdings in the north of the suburb were developed before sewer connections and still use, or once used, septic tanks and soakaways. These are the usual source of nitrate and bacteria in granite groundwater, so the borehole should be sited well apart and upslope from them, and the water checked once the hole is finished.
Small complex gardens leave little room for a rig. In townhouse developments the only open space may be a narrow strip of garden behind a unit or a shared lawn. Trustees and neighbours need to agree on rig position, noise and spoil, and sometimes a different spot on common property, closer to the visitors' parking, is the practical answer.
What the Water Is Used For
- Irrigating vegetable patches and orchards on holdings
- Watering shared lawns in townhouse complexes
- Supplying stables, kennels or poultry on larger plots
- Pool and garden use for freestanding homes
- Standby supply when municipal pressure drops
Wellpoint or Borehole?
Rarely. Outside the narrow alluvial strips beside the Jukskei and its spruits, the ground is clayey weathered granite with water below suction lift. A drilled borehole is the realistic option.
Approval and Abstraction
North Riding falls under the City of Johannesburg. Both main metros require approval before drilling. The City of Johannesburg requires an application to its Environment and Infrastructure Services Department, and an approved application comes with a drilling certificate that has to be kept on site while the rig works; drilling without one risks a fine and impoundment of equipment. The City of Ekurhuleni requires authorisation, with applications reviewed by its Dolomite Section and by Water Demand Management. Elsewhere, including Mogale City, confirm the municipality's current requirements. 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 domestic purposes do not need to register nationally. Commercial, agricultural and larger abstraction may need registration or a water use authorisation. Rules change, so confirm the current position before drilling.

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 - R1,100 /m | The weathered mantle drills fast; fresh granite does not. Deeper holes for larger demand push the total up rather than the rate. |
| uPVC casing, installed, per metre | R400 - R700 /m | Casing runs through the weathered granite, which can be thicker on this open ground. |
| Mobilisation and site establishment | R2,500 - R9,000 | 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 | R60,000 - 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 - 2026 guides quote per-metre drilling rates for Gauteng ranging from under R300/m to R1,500/m, a spread of more than five 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.
North Riding Borehole FAQs
What kind of ground lies under North Riding and its holdings?
The area sits on basement granite and gneiss. A weathered, sandy clay layer of variable thickness covers fresh rock, and the most useful water is usually where fractures, joints or quartz veins cross the transition zone.
Yields from this rock type are generally modest and very dependent on the exact spot, so siting deserves time, particularly on a holding where there are several possible positions and room to choose.
Are owners in Northriding Agricultural Holdings treated differently by the City?
No. Plot size does not remove the need for a municipal drilling application, and Johannesburg must approve it and issue a certificate before a rig arrives on any property, large or small.
Use matters more at national level: reasonable household use falls under Schedule 1, but selling water or farming commercially may need DWS registration or authorisation.
Can a North Riding townhouse owner drill a borehole alone?
Usually not without the body corporate, because the ground in most sectional title schemes is common property. A trustee resolution and agreement on access and water sharing normally come first, and some schemes put the matter to a general meeting of owners.
Some complexes choose a single shared borehole for communal irrigation, which spreads the cost and keeps the work to one location. A sub-meter on the line makes later disputes about usage easier to settle.
Is it worth testing the water from a North Riding borehole?
Yes. While granite water is often fairly soft and clean, older holdings with septic systems, animals and fertilised gardens can affect a shallow aquifer, and conditions can differ from one plot to the next.
Testing before the water goes near a kitchen tap, or before it is given to livestock, is a small step that removes guesswork.
