Water Backup
Backup Water Storage Solutions for Your Home
Never lose water pressure again. Our municipal backup systems keep your household running — even when the mains don't.
What Is Municipal Backup Water Storage?
A municipal backup water storage system is a dedicated water tank connected directly to your home's main supply line. The tank fills automatically when municipal water is available, storing a reserve that your household can draw from the moment the mains are interrupted. Unlike emergency water drums or portable containers, a properly installed backup system delivers pressurised, potable water to every tap, shower, and appliance in your home — seamlessly and automatically. For Johannesburg homeowners dealing with ageing infrastructure, scheduled maintenance shutdowns, and unexpected supply interruptions, a backup water storage system isn't a luxury. It's peace of mind.
How Does a Backup Water System Work?
The system is straightforward, reliable, and designed to operate with minimal input from you.
- Step 1: Your Tank Fills Automatically
The storage tank is plumbed into your municipal supply line before it enters your home. A float valve at the top of the tank controls the water level — when the tank isn’t full, the valve opens and allows municipal water to flow in. Once full, it shuts off automatically. No switches, no monitoring required.
- Step 2: Water Levels Maintained Automatically
When municipal pressure drops or supply is interrupted, a pressure-sensitive booster pump activates automatically. It draws water from your storage tank and pumps it into your home’s plumbing system at consistent pressure.
- Step 3: Normal Supply Resumes
When the mains come back online, your tank begins refilling for the next interruption. The cycle is fully automatic.
Key System Components
- Water storage tank: Available in sizes from 750 litres to 10,000+ litres depending on your household's needs
- Booster pump with pressure sensor: Detects supply interruption and activates automatically
- Float valve kit: Controls tank filling from the municipal line
- Non-return valves: Prevent backflow into the municipal supply
- Ball valves: Allow you to isolate sections of the system for maintenance
- Pump-to-tank connector kit: Ensures a clean, reliable connection between your tank and pump
Optional add-on: A whole-house or undersink water filter can be added for households that want an extra layer of water quality assurance.
Why Homeowners Are Investing in Backup Water Storage
- Uninterrupted Water Supply: No more filling bathtubs the night before a scheduled shutdown. Your household continues to operate normally — showers, washing machines, dishwashers, and toilets all function as expected, even during extended water cuts.
- Fully Pressurised: Delivery This isn't a gravity-fed trickle. The booster pump delivers water at proper pressure throughout your home, so you won't notice the difference between mains and backup supply.
- Clean, Safe Water: Your tank stores treated municipal water — the same water that flows from your taps every day. For added peace of mind, an optional filtration system can be installed to remove any residual contaminants.
- Automatic Operation: The system requires no manual intervention. It fills when water is available, activates when it's not, and resets when supply returns. Set it up once and let it run.
- Protects Your Property: Consistent water supply means your garden irrigation stays on schedule, your pool levels stay topped up, and your household routines aren't disrupted — protecting both your lifestyle and your property value.
- Scalable to Your Household: Whether you're a couple in a townhouse or a family of five in a freestanding home, the system is sized to your daily usage. A simple calculation — the number of people multiplied by 150 litres per day, multiplied by the number of backup days you want — determines the ideal tank size.

Just like our pool installations, our commitment doesn’t end when the job is done. We provide guidance on simple maintenance practices — like rotating your stored water every two weeks — to keep your system performing at its best.
