Water Works & Infrastructure Guide for South African Properties
Municipal connections, tanks, pumps & pressure systems
South Africa's water infrastructure challenges — from municipal supply interruptions to aging pipes — make understanding your property's water systems more important than ever. This guide covers everything from municipal connections to off-grid water storage solutions.
JoJo Tank Installation Guide
JoJo tanks are the most popular water storage solution in South Africa, providing backup water during outages and reducing reliance on municipal supply.
- Tank sizes: 500L (small), 2,500L (standard), 5,000L (large), 10,000L (commercial)
- Placement: On a level, compacted base — concrete slab recommended for tanks over 2,500L
- Inlet: Connect to municipal supply with a float valve for automatic refilling
- Outlet: Gravity-fed (tank must be elevated) or pump-assisted
- Overflow: Direct overflow away from foundations
- First-flush diverter: Essential if collecting rainwater from roof
Understanding Water Pressure Problems
Water pressure issues affect everything from shower performance to appliance lifespan. Both high and low pressure cause problems.
- Normal pressure: 200–400 kPa (2–4 bar) for residential properties
- High pressure (>500 kPa): Damages pipes, geysers, and appliances — install a PRV
- Low pressure: Could indicate a leak, blockage, or municipal supply issue
- Pressure reducing valve (PRV): Protects your plumbing from high municipal pressure
- Pressure booster pump: Increases pressure for properties on low-pressure supply
- Check your meter: A spinning meter with all taps closed indicates a leak
Municipal Water Connection Process
New connections or upgrades to municipal water supply require formal applications and compliance with local municipality standards.
- Application: Submit to your local municipality with property details
- Pipe sizing: Minimum 15mm for residential, 20mm+ for commercial
- Water meter: Installed by the municipality at your cost
- Compliance certificate: Required for all new connections
- Backflow prevention: Required by most municipalities to protect the water network
- Timeline: Allow 4–12 weeks for municipal approval and installation
Borehole Pump Installation
A borehole provides an independent water source for irrigation, household use, or industrial applications. Proper pump selection and installation is critical.
- Pump type: Submersible pumps are most common for boreholes
- Pump sizing: Match to borehole yield and your water demand
- Pressure tank: Prevents pump short-cycling and extends pump life
- Electrical supply: Dedicated circuit with correct cable sizing
- Water quality testing: Essential before using for drinking or irrigation
- Maintenance: Annual inspection of pump, cable, and rising main
Frequently Asked Questions
How much does a JoJo tank installation cost?
A 2,500L JoJo tank with basic plumbing connections costs R8,000–R15,000 installed. Adding a pressure pump and full integration with your household plumbing costs R15,000–R25,000.
Can I use borehole water for drinking?
Borehole water must be tested before use for drinking. Many boreholes have elevated mineral content or bacterial contamination. We recommend annual water quality testing and appropriate filtration.
What is a pressure reducing valve and do I need one?
A PRV reduces high municipal water pressure to a safe level for your plumbing. If your municipal pressure exceeds 400 kPa, a PRV protects your pipes, geyser, and appliances from damage.
How long does a borehole pump last?
Quality submersible pumps last 10–15 years with proper maintenance. Annual inspections, correct pump sizing, and protection against dry running significantly extend pump life.
