Borehole Water Filtration Systems Cape Town & South Africa
Why You Need Borehole Water Treatment
Borehole water in South Africa often contains sediment, iron, manganese, bacteria, and elevated TDS levels that make it unsafe or unpleasant for household use. Without proper treatment, borehole water can cause:
- Brown/orange staining on sinks, toilets, and laundry (iron)
- Sediment buildup that clogs pipes and appliances
- Bacterial contamination (E.coli, coliforms) — health risk
- Bad taste and odour from dissolved minerals
- Scale deposits on geysers and kettles
The 4-Stage Borehole Water Treatment Process
Stage 1: Sediment Pre-Filtration
Remove sand, silt, rust, and suspended particles before they damage downstream equipment.
- Product: 20" Big Blue 5 Micron Sediment Cartridge — R195
- Replace: Every 6 months (or sooner in high-sediment areas)
Stage 2: Carbon Filtration
Remove chlorine, organic compounds, taste, and odour.
- Product: 20" Big Blue Carbon Block Cartridge — R349
- Replace: Every 6–12 months
Stage 3: UV Sterilization
Kill bacteria, viruses, and parasites with ultraviolet light. Essential for any borehole or untreated water source.
- Product: 55W UV Sterilizer Complete Set — R2,695
- Replace lamp: Every 12 months — R649
Stage 4: Final Polishing (Optional)
For drinking water, add a reverse osmosis system to remove dissolved solids, heavy metals, and salts.
- Product: 5-Stage 75GPD Home RO System — R2,695

How to Test Your Borehole Water
Before buying any filtration system, test your water to identify specific issues.
- Product: TDS Meter / Water Test Kit — R249
- A TDS reading above 500 ppm suggests RO treatment may be needed.
- Any bacteria detection requires UV sterilization at minimum.
Frequently Asked Questions
Q: Do I need UV sterilization for borehole water?
A: Yes, if the water will be used for drinking, cooking, or bathing. Borehole water can contain bacteria even if it looks clear.
Q: How often do I need to replace borehole water filters?
A: Sediment filters every 6 months, carbon filters every 6–12 months, UV lamps annually. RO membranes every 1–3 years.
Q: Can I connect a borehole filtration system to my whole house?
A: Yes. A 3-stage Big Blue system with UV is designed for whole-house flow rates. The RO system would be added under the kitchen counter for drinking water only.
Q: What size system do I need?
A: This depends on your household size and flow rate. Contact our engineering team for a free sizing recommendation.
