Edenvale lies on the eastern flank of the granite dome, within Ekurhuleni. A weathered granite cover sits over harder rock, and boreholes commonly tap fractures and the transition band between soft and sound granite.
Older Edenvale suburbs such as Eastleigh, Dowerglen and Hurlyvale have established freestanding homes on decent stands, while Greenstone Hill and the Modderfontein side bring newer estates and security complexes.
What Is Under Edenvale
| Formation | Where it sits | What it means for drilling |
|---|---|---|
| Johannesburg Dome granite and gneiss | The basement rock under the whole suburb, part of the Kaapvaal Craton | Hard, slow drilling once fresh rock is reached. It holds water only in joints, fractures and quartz veins, so the hole has to intersect them to produce. |
| Decomposed granite (saprolite) | The upper few metres to tens of metres on most stands | Drills quickly but is unstable, sandy and clayey. It has to be cased off, and its thickness sets the casing length. |
| Dolerite and diabase intrusions | Thin sheets and dykes crossing the dome | The intrusion itself yields little, but the broken contact zone alongside it is often the most productive ground on the property. |

- Siting targets fractures and dyke contacts because unbroken granite carries almost no water.
- The upper section drills fast and the fresh rock slowly so the total time depends on where one becomes the other.
- Granite water is usually soft and of good quality though nearby septic tanks and soakaways are worth keeping well clear of.

What to Watch For Here
Ekurhuleni has its own authorisation process. Edenvale falls under the City of Ekurhuleni, not Johannesburg. Authorisation is required before drilling, and applications are reviewed by the City Planning Department's Dolomite Section and by Water Demand Management. Allow time for that review and confirm the current requirements with the municipality before booking a rig.
Newer estates near Greenstone have their own rules. Greenstone Hill and Modderfontein estates often have HOA or estate rules covering boreholes, contractors and working hours, and some prefer a shared borehole for common areas. Check those rules and get written consent before lodging the municipal application, so the two processes do not conflict.
What the Water Is Used For
- Watering gardens on older Eastleigh and Dowerglen stands
- Irrigating estate common areas near Greenstone Hill
- Standby supply for Edenvale households during outages
- Filling pools during the long dry winter
- Irrigating vegetable gardens and fruit trees at home
Wellpoint or Borehole?
Not usually. The clayey weathered granite here is not the clean sand a wellpoint needs, and groundwater generally sits deeper than a surface pump can lift. Drilling is the route to a reliable supply.
Approval and Abstraction
Edenvale falls under the City of Ekurhuleni. 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.

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 - R1,100 /m | Decomposed granite drills quickly; fresh granite is slow and wears bits. The split between the two on your stand sets where the cost lands. |
| uPVC casing, installed, per metre | R400 - R700 /m | The depth of decomposed granite decides how much casing is needed, and it changes across short distances. |
| 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.
Edenvale Borehole FAQs
What is the ground like under Edenvale for drilling?
Edenvale sits on the east flank of the granite dome, so drilling typically passes through decomposed granite before reaching hard rock. Water is held mostly in fractures and along dyke or vein contacts.
Yields in this setting are usually modest, and each stand behaves a little differently, so a test pump after drilling sets realistic expectations.
How is Edenvale drilling authorisation different from Johannesburg?
Edenvale is in Ekurhuleni, which requires authorisation before drilling. Applications go to the City Planning Department's Dolomite Section and to Water Demand Management for review, rather than to a Joburg department, even though Edenvale itself sits on granite.
Confirm what is currently required directly with Ekurhuleni before booking any work, because municipal processes are still being refined and can change.
Can Greenstone Hill estate homes drill their own boreholes?
That depends on estate rules. Some estates allow private boreholes on individual stands, while others would rather have a single estate borehole serving the common landscaping. Check with the HOA before making plans.
Municipal authorisation from Ekurhuleni still applies on top of any estate approval, so both need to be in place before the rig arrives.
What affects the cost of a borehole on an older Edenvale stand?
Depth, the length of casing needed through weathered rock, the pump and storage tanks all affect cost. None of these can be fixed before drilling, because the ground decides them.
Older Edenvale stands may also need extra care around established gardens, pools and old services that were never properly mapped.
