Water is the one variable that can cut a trip short faster than anything else. A puncture you can fix. A drained battery you can jump. Run out of drinking water two days from the nearest tap and your options get narrow quickly.
Planning your water storage properly means you can go further, stay longer, and spend less time worrying about supply.
How much water do you actually need?
The rough baseline for overlanding is three to five litres of drinking water per person per day. Add cooking, washing up, and the reality that hot weather increases consumption, and a four-day trip for two people realistically needs 30 to 50 litres of clean drinking water as a minimum. That's before you account for vehicle passengers or any extended off-grid time.
The calculation is simple, but people routinely underestimate it. A few jerry cans from the garage that you fill the morning you leave is not a water strategy.
IRONMAN 4x4 Water Storage Options
The IRONMAN 4x4 water storage range gives you multiple formats so you can match your storage to your vehicle and how you pack.
The jerry can options, 20L with tap and 40L double format, are the most flexible. They're portable, easy to fill from any tap or water point, and can go anywhere in the bakkie tub or on a roof rack. The tap on the 20L makes dispensing straightforward without needing a pump.
For larger dedicated capacity, the rectangular 60L and vertical 40L tanks mount semi-permanently in the tub. They give you substantial volume without taking up floor space you need for gear. The low-height 50L is designed specifically for roof rack mounting, keeping weight low and centre of gravity where it should be when you're on rough terrain.
The 50L wheel arch tank is shaped to fit neatly alongside wheel arch intrusions in bakkie tubs. This is an efficient use of space that would otherwise be wasted, and at R2,240, it adds meaningful capacity without sacrificing usable tub area.
For overlanders who want a more integrated solution, the 30L 12V powered tank includes an integrated electric pump at R8,990. Turn a tap, get water. No bailing with a cup, no gravity-fed gravity problems. It's the choice for setups where convenience matters as much as capacity.
12V Pressure Pump
If you're running one of the unpowered tanks and want the convenience of a tap, the IRONMAN 4x4 12V pressure pump at 12.5 litres per minute connects directly into your tank and delivers pressurised water on demand. It's the upgrade that makes your camp kitchen feel more like a kitchen and less like a field exercise.
A few things to know before you buy
Food-grade plastic matters. All IRONMAN 4x4 water tanks are designed to carry drinking water safely. Don't cross-contaminate by using the same container for water and fuel, even temporarily.
Position your tanks low and centred where possible. Water is heavy. A full 60L tank weighs 60 kilograms. Where you mount it affects your vehicle's handling, especially on corrugations and side slopes.
Think about access. A tank you can't easily refill or drain is a tank you'll stop using. Consider where your fill points are and whether you can reach them without moving half the kit in the tub.
Water independence is range independence
The further out you go, the more your water supply determines how long you can stay. Build your water storage as deliberately as the rest of your overlanding setup and it'll be one less thing you're managing in the bush.
