This is not new. A similar thing called a Hippo has been around for years in South Africa and the surrounding countries. For some reason it never really took off - probably too expensive.

this gives me the idea of a wheelbarrow with this as the wheel... could carry more than just water or more containers of water :D
Hippo Water Roller
Wally, thank you for pointing this out. Hippo Water Roller is still going strong (invented in 1991). Please visit our website to learn more: hipporoller (dot) org It is expensive, but it is designed to be long-lasting, plus includes many benefits.
Sam, you may want to view the Hippo Spaza option - to support your idea.

No energy expert here, the less in water treatment but since you have the kinetic energy there by rolling that wheel wouldn't be useful to add a generator and perhaps a battery to store that energy and use it later in a lamp or a radio or even using that power to purify that rolling water by electrolysis?

The WaterWheel is an excellent solution to water transportation in vulnerable communities. But wait just a sec! Please feel free to call me cynical but:
1. The similarity in design and construction is remarkably, no, correction, suspiciously, similar to the Hippo Water Roller. Am I to believe that these two virtually identical solutions were developed separately by parties that are continents apart? Yes of course they were! Now pull the other leg! It’s got bells on! 2. From a design and development background I am obliged to conclude that one of these must be a bootleg “replica” (yeah right!) of the other. 3. So which came first? Well the Hippo Water Roller has been around since 1991. So the bootleg “replica” must be….hmmm …no…no... give me a minute. I’m sure I will work it out.

I'd be more impressed if a filter was used to clean the water as it rolled along and the filter could be changed or cleaned easily and with no advanced technology required.

Errr, I remember using something very similar to collect water from a standpipe back in the 1950's when on caravan holidays in Cornwall. It seems it has taken some time for the word to spread!

I didn't notice anything in there about purification... did I miss it? Incorporating a silver-laced element into the hub (or something) that would kill pathogens as it rolled might be an added benefit (if also an added expense - but might be worth it?)
A big challenge with these projects is maintenance (beyond the initial investment). If something breaks, they have no way to repair it or even the training as to how to get it working again, so the whole investment is lost, and they're back to square one.
Building it from locally available components, providing ongoing education to local servicing providers (even equipping them in their own business enterprise of repair and support), and vision casting upgrade potentials to the users, such as a harness that attaches the wheel to the family goat, to further "automate" the process. ☺

How much $? Cost is always a problem in countries with a $300/capita/year income.

Yes, the Hippo and the Water Wheel are remarkably similar. So too are the conditions that the users of these device live in. I would find it hard to beleive that the Water Wheel folks are trying to rip off anyone, since there appear to be greater priorities in play. If you can't say something nice.....
