A technology so simple, it just might impact the lives of millions of people around the world.
For people in developing countries, getting clean water to cook with, clean with, and drink, can be a difficult and dangerous task. In rural areas, it often requires miles-long treks to the source and back again with a load weighing upwards of 30 pounds. We’re all familiar with the images of women in developing countries carrying large vessels on their head, which can lead to neck and spinal injuries. Piet Hendrikse wanted to find another way. His solution was the Q Drum.
Essentially a plastic cylinder with a hole through the middle, the Q Drum can be filled with water and rolled along the ground with rope or even old clothes tied together. The outer plastic is durable so that it won’t puncture during long treks over rough terrain. Empty, the Q Drum weighs just under 10 pounds. Filled with water it weighs 120 pounds – try hoisting that back from the river.
Now, even young children can bring back adequate amounts of water.
Water is heavy. The average person can lug up to about 15 liters (almost 4 gallons) of water. The Q Drum has the capacity of 50 liters (over 13 gallons). Q Drum’s lightweight but durable polyethylene material maximizes its weight-carrying efficiency. The hole in the middle becomes a support shaft during water storage. Normal water containers can only be stacked a few feet high before collapsing. But during compression testing, the Q Drum could withstand 3.7 tons – equivalent to about 40 full stacked Q Drums. The Q Drum’s durability also means they’ll withstand about 8 years of everyday use.
The drum can serve to transport other things as well, like foodstuffs or clothes. And if some soap and water are added, the drum becomes a portable, manual clothes washing machine. Outside of the developing world, it can be useful in bringing water to those in need following natural disasters.
Sometimes it pays to reinvent the wheel.
Hendriske got the idea for the Q Drum while driving past villages near his home in South Africa. He saw people using wheelbarrows and old water drums to transport larger amounts of water and thought there must be a better way. The solution was so simple people wondered why no one had thought of it before. He made a prototype, offered it to the villagers, and, as he told Kopernik, where the drum is available for purchase, “They were crazy about this thing!”
But as simple as the Q Drum is, manufacturing it in a cost-effective manner is not. To make the cylindrical hole requires rotational moulding, a lengthy and expensive process. Another challenge are transport costs, which are often higher than the cost of the drums themselves. This is a major problem. As stated on the Q Drum website: “Those that need them ultimately can’t afford them, and those who can most likely don’t need them.”
Right now Q Drum makers are trying to align themselves with manufacturers inside the countries where they’re needed. By manufacturing them locally they hope to not only reduce costs but to also benefit those in-country operators.
Hendriske showcases the Q Drum in action in the following video. He also beckons to those with “resources” to “help get the Q Drum to the people who need it most.”

This is not much different than the hippo invented years ago. Same idea. It’s tough to fill and to empty. Leads to contamination. In the US we fly water from FIJI in little bottles. Best we can come up with is plastic drums for people to roll. Give me a break. More UN dollars going down the drain. Invest in wells and pipes.

Thanks. I hadn’t heard of the Hippo.
hey- I kind of like this….. But what exactly is that wheel made out of? “polyethylene” – What are the pro’s/ con’s of this material as opposed to some sort of water-soluble all natural material?

Also, from a purely hypothetical “all terrain design” stand-point, why did they not put treads on the point of contact with the ground? It’s hard to tell from the small photo, but I feel like treads would help with up hill/ down climbs, which could be a concern.
It’s a durable plastic. Not the most environmentally friendly way to… I don’t know what treads would do but it seems to roll pretty well in the video. Once the momentum is up, probably going to be okay.
The issue of water access is rightly identified as a critical one. A similar solution, the Hippo Water Roller, has been around for twenty years, and doesn’t have the same manufacturing issues as this Q Drum.

It is also a rather old idea that could have changed the world by now if it was ever going to.

But apparently an easy way to carry water is not their biggest problem :-S
Yeh I’m with this.
No offense, but my response to this article was, “Yeh… right.”
Like no1 could come up w/ a wheel before? srsly? It may be some 3rd world country, but come on. They just use those jugs because its what they had on hand and was free. And then how r u supposed to pour it out. come on now. this isn’t anything revolutionary.
“The people who need it can’t afford it. The people who can afford it don’t need it” Seems like some cheap gimmick to make money to me. Even if the guy may have good intentions. I’m sorry, but I’m jsut not buying this 1… :/
How is that better than 2 wooden wheels (or one), couple of planks and any kind of a water tight container?
Just print them out…
Plastic is the wrong solution. Find a way to modify a 55 gallon drum instead. Cut a drum at the meridian, fasten waterproof spools through the centers by crimping, and you have two water wheels. Use what they already have.
What a great invention for rural areas! Let’s hope that this idea will be supported, and that local manufacturers can see the value in offering a cost-effective product like this. goo.gl/p4Vge
