Where to Buy a Water Tank, JoJo, or Emergency Backup in Johannesburg [2025 Guide]

When the taps run dry in Joburg, panic-buying bottled water isn’t your only option. More residents are turning to JoJo tanks and backup water storage systems to stay ahead of service disruptions, especially with water outages now hitting as often as load shedding in some parts of the city.

Why Jozi Homes Are Investing in Water Storage

Whether it’s a burst pipe in Parkhurst or another Rand Water shutdown, Johannesburg’s water supply is becoming less predictable. In 2025, backup water tanks aren’t just for farms or factories; they’re part of urban survival.

A growing number of Jozi homes and small businesses are installing JoJo tanks [or similar brands] to store rainwater, borehole water, or municipal supply as a reserve. With reliable plumbing and proper filtration, some residents are even using their tanks for drinking water.

Top Places to Buy Water Tanks and JoJo Systems in Joburg

You’ve got options, from big-box stores to specialised installers. Here’s where locals are shopping for backup water systems in 2025.

Builders Warehouse

Still one of the city’s go-to destinations for JoJo tanks. Builders stocks a wide range of sizes, from compact 750-litre tanks for balconies to large vertical tanks suitable for gardens or commercial spaces. You’ll also find plumbing fittings, stands, and pressure pumps.

Makro

Ideal if you’re looking to combine your tank purchase with other bulk essentials. Makro stores typically stock JoJo and similar brands, along with accessories for installation and maintenance.

K. Carrim

This longstanding Gauteng retailer offers both in-store and online options for water storage systems. Look out for JoJo tanks as well as other high-quality brands like Lin Tanks, with sizes ranging from 500 litres to 10,000 litres.

RainHarvest

A specialised supplier focusing on rainwater harvesting, filtration, and full-system installations. While they stock JoJo tanks, their real value lies in tailored solutions for eco-conscious homes and drought-ready properties.

Local Pros

Think of them as the installers rather than just a retailer. Local Pros connects you with certified JoJo tank installers who understand Joburg’s unique water infrastructure challenges.

X-treme Cleaning Solutions

Based in Gauteng, they offer water delivery services and flexible bladder storage tanks for temporary or mobile use. They’re a popular choice for emergency setups during municipal cutoffs or building-wide outages.

Rainbow Reservoirs

Known for durable, custom-designed steel and polymer tanks. While not your everyday home solution, Rainbow Reservoirs is ideal for those needing industrial-grade water storage on farms, estates, or businesses in outlying areas.

Online Platforms

Websites like Takealot and ThirtyOne.co.za make it easier to browse and order JoJo tanks for home delivery. Be sure to check delivery costs, tank weight, and whether installation is included or extra.

How to Choose the Right Tank

Before you swipe your card or place that online order, consider the following:

• Size matters
  A 1,000-litre tank is ideal for a small household’s emergency needs. Larger families or those wanting to run irrigation systems might need 2,200 litres or more.

• Material
  UV-resistant, food-grade polyethylene (like JoJo uses) is best for long-term water storage in the Joburg sun.

• Water Source
  Are you storing municipal water, rainwater, or borehole supply? Each has its own filtration and pump needs.

• Filtration and Purification
  If you plan to drink the stored water, install a proper filtration system, especially for rain or borehole sources.

• Installation
  Get a solid, level base. You’ll need correct piping and fittings to prevent leaks. Some tank retailers offer full installation packages, which is worth the cost for peace of mind.

Backup Water Isn’t Just a Trend; It’s a 2025 Essential

As Johannesburg continues to battle infrastructure strain, climate shifts, and ageing reservoirs, water independence is no longer a luxury.

Social media is already full of Jozi residents sharing their tank setups, some proudly installing rooftop JoJos, others turning their backyards into mini reservoirs. It’s not just about weathering the next outage. It’s about building resilience and protecting your daily routine when taps run dry.

So whether you’re stocking up before the next water outage or planning to go off-grid in the suburbs, having a water backup system in 2025 is just smart living in Joburg.
