More than just a water tank
A complete backup solution, designed for your home.
A tank on its own is only part of the answer. A dependable backup system brings together the right storage capacity, pump, plumbing and automatic controls, so your property can keep receiving water when the municipal supply is interrupted.
- Store municipal water while the supply is available.
- Draw on stored water through a properly designed pump and changeover arrangement.
- Select the pump to suit your household's flow and pressure needs.
- Plan around your household size, usage and available space.
Our solutions
Everything working together.
We bring the key parts of a water backup installation together into one practical system for your home or business.
Water storage tanks
Opaque, UV-resistant tanks sized to your household’s usage, the backup period you want to plan for and the space available.
Booster pump systems
Pumps selected against your required flow and pressure, with dry-run protection and isolation valves for servicing.
Automatic changeover
Level sensing and control arrangements that move between municipal and stored water, with the supplies kept safely separated.
Backup power compatibility
Where your inverter has enough continuous and surge capacity, the pump may keep running during a power interruption. We check first.
Plumbing & installation
Tank position and base, pipe routes, isolation points, a screened overflow and the connection to your existing plumbing.
Servicing & maintenance
Keep the system in good order with checks of the pump, controls, valves, overflow and storage components.
Images are illustrative of typical residential installations.
How it works
How a municipal water backup system works.
The exact configuration is selected for your property, but a typical automatic system works in three situations.
Municipal supply available
The system can replenish the storage tank as designed, maintaining a reserve.
Municipal supply interrupted
The stored water can supply the household through the appropriately designed pump and changeover arrangement.
Power backup
Where the inverter system is suitably sized and compatible, the pump may continue operating during a power interruption.
The system must be designed by appropriately qualified professionals, with safe separation of the municipal and stored-water supplies and the applicable plumbing and electrical requirements considered.
A representative example
What a typical home system might include.
This is an example to show how a system comes together, not a standard package. Tank size, pump and controls are chosen after we assess your household’s demand, the site and your existing plumbing.
Example scenario
- Four-person household, single-storey home in Gauteng
- Approximately 2–3 days of backup water for that household's typical use
- Whole-house water supply
- Water tank located in the garden
- Pump intended to run from the inverter, where the existing power system is suitable
| Component | Representative specification |
|---|---|
| Storage tank | 5,000-litre opaque, food-grade water storage tank |
| Tank installation | Suitable level, structurally adequate base |
| Booster pump | Initially assess a 0.75 kW class variable-speed pump |
| Flow target | Approximately 30–40 litres per minute, subject to pressure and pump-curve verification |
| Higher-demand option | A larger pump, potentially around 1.1 kW, if actual demand requires it |
| Controls | Automatic level sensing and pump protection |
| Changeover | Suitable automatic municipal / tank supply arrangement |
| Whole-house filtration | 3-stage (triple) Big Blue system: sediment, activated carbon and carbon block cartridges, fitted after the pump with isolation valves and a bypass |
| Protection | Dry-run protection, isolation valves and appropriate backflow / cross-connection prevention |
| Overflow | Properly screened and safely directed overflow |
| Backup power | Verify inverter continuous and surge capacity, pump starting characteristics and battery reserve |
We also install other tank sizes and pump configurations. Actual backup duration, flow and pressure depend on your household’s usage and the installed system, and inverter compatibility is confirmed during the assessment. Prices are quoted per property.
The BHG approach
A solution shaped around your requirements.
From a family home to a busy workplace, a properly planned water reserve can help reduce disruption when the municipal supply is unreliable. It starts with understanding how much water you use and how your property is connected.
Property-specific design
Recommendations based on your layout, usage and installation space.
Right-sized storage
A practical reserve for the outages you want to prepare for.
Automatic operation
Less need to switch valves or operate equipment by hand.
Power considerations
Inverter or generator compatibility checked for pump operation.
Safety-conscious setup
Backflow prevention, overflow and pump protection accounted for.
Ongoing support
Servicing to keep your installation in good working order.
Don't wait for the next outage to think about your water supply.
Tell us about your property and we’ll recommend an appropriately sized system.
Helpful information
Frequently asked questions.
Some of the things to consider when planning a water backup installation.
It depends on how many people live in the home, your daily usage, how long an outage you want to plan for and whether the system will supply the whole property. We recommend a capacity after assessing your household.
For some households it may, but not for all. Our example assumes a four-person household’s typical usage. Your actual backup period depends on how much water your household uses during an outage.
No. That is a representative starting point. We can recommend a larger or smaller tank, a different pump, or a multi-tank arrangement to suit your demand, site and plumbing.
An appropriately designed system can switch to stored water automatically when the municipal supply is interrupted. The control method is selected to suit your existing plumbing, with the municipal and stored-water supplies kept safely separated.
It may, if your inverter or generator has enough continuous and starting (surge) capacity and battery reserve. We check the pump and your backup power system for compatibility before recommending this.
Flow and pressure depend on the pump selected, pipe sizes and your home’s layout. We verify these against the pump’s performance curve during design rather than promising a figure up front.
Most existing homes can be assessed for a retrofit. Space, access, pipe routes, the municipal connection and your current plumbing will shape the final design.
A few details and photos help with an initial recommendation. A site visit is usually needed to confirm measurements, pipework, pump requirements and the final installation scope.
