Breakdown: What Influences Water Tank Installation Cost in Johannesburg?
Johannesburg has unique installation conditions:
✔ Hard water areas
✔ Pressure fluctuations
✔ Frequent supply interruptions
✔ High-demand homes and estates
✔ Sloped stands and limited yard space
Because of this, a professional SANS-compliant installation is essential.
Below is the detailed cost breakdown.
1. Tank Size & Brand
The bigger the tank, the higher the price — but the cost per litre decreases with size.
| Tank Size | Tank Cost (JoJo / Eco / Roto) |
|---|---|
| 500L | R1,200 – R1,800 |
| 1,000L | R1,800 – R2,800 |
| 2,200L | R2,800 – R4,500 |
| 5,000L | R5,500 – R9,500 |
| 10,000L | R12,000 – R19,000 |
JoJo remains the most requested brand due to warranty and SANS plastics compliance.
2. Base/Foundation Cost
A strong foundation prevents tank leaning, cracking, & pump failure.
| Base Type | Cost |
