In South Africa, having a reliable backup water supply is quickly becoming less of a luxury and more of a practical investment.
Whether you’re dealing with temporary municipal interruptions, maintaining a garden during dry periods, running a business or simply wanting greater control over your water supply, installing a water storage tank can provide valuable peace of mind.
For homeowners, farmers and businesses searching for water tanks for sale in South Africa, MoveDit offers an easy way to shop online for new Africa Tanks and other garden and outdoor products.
Why Should You Have a Backup Water Tank?
Think about how many everyday activities depend on water.
Cooking.
Cleaning.
Flushing toilets.
Showering.
Washing clothes.
Watering gardens.
Running a business.
Looking after animals.
When the municipal supply stops, even temporarily, normal life can quickly become inconvenient.
A water storage tank gives you the ability to keep water available on your property so that you’re better prepared when supply is interrupted.
A properly designed municipal backup system can store municipal water while supply is available and then use that stored water during an interruption.
Water Backup Is Becoming Part of Modern Home Planning
South Africans have become accustomed to thinking about backup electricity.
Solar panels, batteries, inverters and generators have become common conversations.
Water deserves similar consideration.
A home’s essential infrastructure increasingly includes thinking about:
Power backup + Water backup
A water tank can become part of a property’s long-term infrastructure rather than something purchased only when there’s already a problem.
How Does a Municipal Backup Water System Work?
A basic system can be surprisingly straightforward.
The storage tank is connected to the municipal supply and fills while municipal water is available. A float valve can automatically stop the incoming water once the tank reaches the required level.
When water is needed, a pump can supply pressurised water from the tank back into the home.
Non-return valves and other plumbing components are important to prevent back pressure into the municipal supply, and professional installation is recommended when integrating the system into a building’s main plumbing.
That means your tank doesn’t necessarily have to sit outside waiting for you to fill buckets.
A correctly designed system can provide a much more convenient backup solution.
What Size Water Tank Do You Need?
This is one of the first questions buyers ask when searching for a water tank for home use.
The answer depends mainly on:

• Number of people using the water
• How much water you normally consume
• How many days of backup you want
• Available installation space
• Whether the tank will also collect rainwater
• Whether the property is residential, commercial or agricultural

As a general planning guideline, JoJo uses approximately 150 litres per person per day when estimating municipal backup requirements.
For example, a household of four would use an estimated:
4 people × 150 litres = 600 litres per day
For three days of backup:
600 litres × 3 days = 1,800 litres
Actual consumption can be considerably lower or higher depending on the household, so treat this as a planning guideline rather than a fixed requirement.
Don’t Automatically Buy the Smallest Tank
When choosing between water tank sizes, think beyond what you need today.
Ask yourself:
Will my family grow?
Could water interruptions become longer?
Do I want to collect rainwater too?
Will I use stored water for my garden?
Do I have enough space for a larger tank?
Water-storage manufacturers generally recommend considering the largest practical capacity that your available space, application and budget allow.
Storage capacity is something that’s difficult to appreciate until you actually need the water.
Water Tanks Aren’t Only for Emergencies
One of the biggest advantages of installing a water tank is that it can potentially serve several purposes.
Municipal Water Backup
Store municipal water for use during interruptions.
Rainwater Harvesting
Collect rainwater from your roof and store it for later use.
Rainwater can potentially be used for applications such as garden irrigation, washing vehicles and filling swimming pools, depending on the system and water quality. Water intended for drinking requires appropriate treatment and filtration.
Garden Irrigation
Instead of using potable municipal water every time you water the garden, harvested rainwater can provide an alternative source.
Agricultural Use
Farms and smallholdings frequently require stored water for irrigation, cleaning, animals and general operations.
Business Backup
Restaurants, offices, workshops, guest houses, accommodation establishments and many other businesses can be severely disrupted when there’s no water.
Having reserve capacity can help reduce that vulnerability.
Why Rainwater Harvesting Makes Sense
When rain falls onto your roof, much of that water would ordinarily run into gutters and eventually drain away.
A rainwater harvesting system captures some of that water and directs it into storage.
A typical setup can include:
Roof → Gutters → Pre-filtration → Water Tank → Pump → Intended Use
Rainwater harvesting can reduce reliance on treated municipal water for suitable non-potable applications and provide an additional stored-water source.
For homeowners with gardens, this can be particularly useful.
Choosing the Right Type of Water Tank
Not every property has space for a large traditional vertical tank.
Fortunately, water tanks come in several configurations.
Vertical Water Tanks
A popular choice when maximum storage capacity is the priority and sufficient ground space is available.
Slimline Water Tanks
Ideal for properties with limited space, particularly alongside houses or boundary walls.
Low-Profile Tanks
Useful where height restrictions are a consideration.
Horizontal Tanks
Horizontal or transporter-style tanks can be suitable for applications where water needs to be transported.
Underground Tanks
An option where homeowners want to preserve above-ground space or minimise the visual impact of water storage.
The best choice depends on your available space and what you intend to use the stored water for.

Why Buy a New Water Tank?
When the tank will form part of your home’s water infrastructure, buying new offers several advantages.
You know the tank’s history from day one.
There is no uncertainty about what may previously have been stored inside it.
You can select the appropriate capacity for your needs.
And you can plan the installation correctly from the beginning.
This becomes especially important when you’re considering storing water that could eventually be used domestically.
Installation Is Just as Important as the Tank
Buying a quality tank is only part of the process.
The installation matters too.
Water is extremely heavy.
A 5,000-litre tank contains roughly five tonnes of water before even accounting for the tank itself.
That’s why the base must be suitable.
Manufacturer installation guidance recommends placing tanks on a sound, level, smooth surface that is free of protrusions and sufficiently large to support the entire tank.
Don’t simply place a large tank on uneven ground and fill it.
Plan the installation properly.
What About Pumps?
If you’re simply using the tank to fill a bucket or watering can from a tap, you may not require a sophisticated system.
If you want stored water supplied back into your home at pressure, however, a pump is generally incorporated.
A pressure controller can detect when a tap is opened and activate the pump to move stored water into the home.
Speak to a qualified installer about the correct pump and plumbing configuration for your particular property.
How Long Can You Store Water?
Stored water needs to be managed correctly.
For municipal backup systems, JoJo recommends rotating stored municipal water approximately every two weeks to maintain freshness and ensure the system continues functioning properly.
You could rotate the water by using it for activities such as:

• Watering your garden
• Washing vehicles
• Filling a swimming pool
• General outdoor cleaning

Then allow the tank to refill with fresh municipal water.
The quality of the incoming water remains important, and rainwater or water from uncertain sources should not automatically be assumed safe for drinking without appropriate testing or treatment.
Water Backup for Businesses
Water interruptions don’t only affect households.
For businesses, they can affect productivity and revenue.
Consider a:
Guest house without water for guests.
Coffee shop unable to wash dishes.
Workshop unable to perform cleaning operations.
Office with toilets that cannot function.
Farm without readily available stored water.
Construction site requiring water for daily operations.
For many businesses, a backup water system should be viewed as part of operational continuity planning.

Water Security Starts With Being Prepared
You don’t buy a backup water tank because you want the municipal supply to fail.
You buy one because when it does, you’re prepared.
For a home, it can mean being able to continue with everyday life.
For a garden, it can mean having stored rainwater available when you need it.
For a farm, it can provide valuable additional storage.
For a business, it can help keep operations moving.
And unlike water that disappears down a stormwater drain after rainfall, a properly designed storage system allows you to capture and manage some of that valuable resource.
If you’ve been considering installing a backup water system, now is a good time to determine how much storage your household or business actually needs.
