Frequently Asked Questions

Borehole FAQ — Constantia

Everything homeowners in Constantia ask before drilling a borehole.

How much does a borehole cost in Constantia?expand_more
A complete borehole system in Constantia typically runs between R50 000 and R100 000. This includes drilling (the biggest variable), steel or PVC casing, a submersible pump, electrical connection, and basic yield testing. The Cape Granite formation means percussion (hard rock) is the standard method here, which affects the per-metre drilling rate.
How deep is a borehole in Constantia?expand_more
Most boreholes in Constantia reach between 35m - 70m. The exact depth depends on the local water table and fracture zones within the Cape Granite formation. Your driller will stop once a sustainable yield is confirmed via air-lift testing.
What is the typical borehole yield in Constantia?expand_more
Yield in Constantia ranges from 0.5 - 2.5 l/s depending on where exactly the borehole intercepts fractures in the rock. A yield of 0.5 l/s is generally sufficient for a household; above 1.5 l/s supports irrigation and larger domestic use.
Do I need a permit to drill a borehole in Constantia?expand_more
Yes. All boreholes in South Africa must be registered with the Department of Water and Sanitation (DWS) — Western Cape Regional Office under the National Water Act (Act 36 of 1998). You must also notify the City of Cape Town before drilling. Your drilling contractor should handle or guide you through this registration. Failure to register can result in fines.
Is borehole water in Constantia safe to drink?expand_more
Good quality. Low TDS. Standard potability testing recommended before drinking use. All borehole water should be tested by a SANS 241-accredited laboratory before use for drinking or cooking. Common tests include microbiological (E. coli, coliforms), chemical (iron, nitrates, pH), and physical (turbidity, colour) analysis.
What geology is found in Constantia?expand_more
Constantia sits on Cape Granite. This formation directly determines the drilling method, expected depth, water yield, and cost. Hard-rock percussion drilling is the standard here and delivers reliable results in these conditions.
How long does borehole drilling take in Constantia?expand_more
Drilling typically takes 1–3 days for a standard residential borehole. Add 1–2 days for pump installation and electrical connection. Site preparation, geo-survey, and permit registration can add 1–2 weeks to the total project timeline.
Can I use borehole water for irrigation in Constantia?expand_more
Yes. Most boreholes in Constantia produce water suitable for garden irrigation, lawn watering, and vehicle washing without further treatment. For drinking, cooking, or filling a pool, a basic filtration and purification setup is recommended.
Does a borehole increase property value in Constantia?expand_more
Generally yes. A registered, operational borehole with a good yield is a significant asset in Constantia, particularly given municipal water pressure and supply challenges. Buyers and estate agents increasingly view a reliable borehole as a premium feature.
What is the difference between a borehole and a well point?expand_more
A well point is a shallow (3–10m), small-diameter tube driven into soft ground to access a high water table — common in coastal areas with sandy soils. A borehole is a deeper, larger-diameter hole drilled through rock to reach a reliable aquifer. In Constantia's Cape Granite conditions, a proper borehole is always required.
