Lynnwood sits on shale in the valley belt of the eastern suburbs, with the ground rising toward the ridge on its southern side.
Yields depend on fracturing rather than depth, so the siting decision carries more weight than any equipment choice made afterwards.
What Is Under Lynnwood
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Silverton Formation shale | The broad valley ground between the northern and eastern quartzite ridges | The thickest shale unit in the Pretoria Group and the rock under most of these suburbs. It drills quickly but is a weak aquifer in itself; yield depends on fracturing rather than on the rock mass. |
| Diabase dykes and sills | Cutting across the shale throughout the Pretoria valley | Often the best target on this ground. Fractures concentrate along the contact between an intrusion and the shale it cuts, and that is where useful yields are usually found. |
| Weathered shale and residual clay | The upper section on most stands | Unstable and moisture-sensitive at the top. Casing down to competent rock is standard practice here. |

- Siting is about finding structure, not depth because the shale itself carries little water between fractures.
- Dyke contacts are the targets worth locating and they are exactly what a survey is looking for on this ground.
- Drilling is comparatively quick so the per-metre rate tends to sit at the lower end of the range.

What to Watch For Here
Lynnwood Ridge changes the picture within the same suburb. The southern parts of Lynnwood rise onto harder ground where quartzite comes closer to surface, and drilling there is slower and more expensive than on the valley floor a few streets away. Where a stand sits on that slope genuinely affects the quote.
Established gardens set a heavy dry-season demand. The planting through Lynnwood is mature and thirsty from roughly June to October. A borehole with storage handles that far better than a borehole sized on flow rate alone.
What the Water Is Used For
- Keeping established gardens alive from June to October
- Keeping the pool level up, depending on the water analysis
- A fallback for when the reticulated supply fails
- School, sports field and institutional grounds
- Reducing a municipal water account that has climbed steeply
Wellpoint or Borehole?
Ruled out. Shale is consolidated rock and the clay above it is the wrong material entirely for a driven point. Even where water is relatively shallow, it is deeper than a surface pump can lift.
Registration and Abstraction
A completed borehole here should be registered with the City of Tshwane, and the responsibility for that sits with the property owner rather than with the driller. Separately, the National Water Act governs how much you may abstract: reasonable domestic use and small-scale gardening generally fall under Schedule 1, while larger, agricultural or commercial abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. The position on domestic registration was being actively revised during 2026, so confirm your obligations before drilling rather than afterwards.

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 | R450 - R1,000 /m | Softer rock means faster progress, so holes here generally sit at the lower end of the metro-wide range. |
| uPVC casing, installed, per metre | R400 - R700 /m | The weathered clay above the rock is what has to be cased through, so its depth decides the length required. |
| 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 | R70,000 - R200,000+ | 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.
Lynnwood Borehole FAQs
Does it cost more to drill on Lynnwood Ridge than in Lynnwood?
Generally yes. The higher ground brings harder rock closer to surface, and hard rock means slower metres and a higher per-metre rate.
It is worth being specific about your street when getting a quote, because the difference within the suburb is real.
How deep are boreholes in Lynnwood?
There is no dependable typical figure. Depth is determined by where a fracture zone or dyke contact is intersected, not by a target horizon.
That is why drilling is charged per metre and why a fixed-price fixed-depth quote tends to be either padded or risky.
Can a borehole replace municipal water entirely in Lynnwood?
Rarely, and it is usually not the sensible goal. Most systems here supplement the municipal supply by taking irrigation off it and providing standby capacity.
Full replacement means potable-standard treatment, monitoring and enough storage to cover every eventuality, which is a much larger project.
What maintenance does a Lynnwood borehole need?
Periodic checks on water level, yield and pump performance, plus retesting water quality. Declining performance is usually gradual and easier to fix if caught early.
Boreholes on fractured shale can also silt up over time, which is what rehabilitation addresses when it becomes necessary.
