Jerrycan Filter Cap to help lighten the burden for women in Third World Countries.

The collection of water forms a significant part of the daily routine for most people in developing countries. It is largely women who bear this responsibility. This collected water is used for not only drinking, but many basic everyday tasks including: Household cleaning Laundry Personal hygiene Growing crops Preparing food Caring for livestock Our concept focusses on improving the issue of water sanitation and wastage. The product was come up with, "Ely", is designed to enable better control of the Water flow from jerrycans as well as providing clean, drinkable water. This is what we have thus far. Please feel free to comment on your thoughts!

We aim for the product to be: 
- Durable 
- Universal (fits on varying plastic jerry cans)
- Filter the water adequately (Ceramic Water fitlers)
- Easily maintained and very affordable. 

The bottom section is tapered with rubber material to allow it to fit on different sized cans and lock in effectively. 

The steps of using the product follows:
Step 1.
It filters larger sediments as the can is filled. This can then be taken out and shaken out.
Step 2.
The top section is placed on top which houses a spree with a Y shaped tunnel. The sphere can be turned using the handle to activate the filter on one of the tunnels for drinking water and a a controlled flow from the other which can be used for washing hands etc. 

We hope this could give people more control of their water use, as well as save on water wastage otherwise caused by water coming directly from the jerry can in late amounts. 

Who will benefit from this idea and where are they located?

Women in the developing countries across Africa.

What kind of help would you need to make your idea real?

Constructive criticism, taking on questions we have not yet uncovered/acknowledged. Any feedback would help immensely. Thanks!

I like the focus of your project Dylan!
Are there any products like this already in use? Will you be able to create one of your designs to test it out? How do you know it will be affordable? You mention this will filter and clean the water. Will the water be clean enough to drink and if so how do you determine that?
Looking forward to hearing more! Good luck!

Great prompts, Bettina! I would also add: are you affiliated with or partnering with an organization that has the capacity to prototype and distribute these cap filters?

Hi Bettina! Here are some answers:

- Are there any products like this already in use? There are examples of jerrycan filters that can be bought as a full product - not to an existing jerrycan. Our outlook was that we should design a small filter that incorporates with what they already have/use on a daily basis.

- Will you be able to create one of your designs to test it out? We are in the process of developing and making a final product that functions well mechanically. The filter element has largely been built from research: video demonstrations, case studies, scientific explanations and physical properties. We're certain the filter works, its figuring out the flow rate and how long the filtration process may take.

- How do you know it will be affordable? We've kept affordability in mind during the process. We're aware that it is a major factor in the success of the product. The piece itself is quite small. We've narrowed the form to 3 pieces for injection mold. The materials (porous ceramic, plastic, mesh, and rubber) are all inexpensive and require small quantities of each. In theory, at a high rate of production (potentially in Asia) the model should come to a cost projection of $1 at the most (50c at best).

- Will the water be clean enough to drink and if so how do you determine that?
Good question. the choice of porous ceramic was long process. Ceramic has shown to remove bad bacteria, viruses, bad tastes and odors well. It does remove small sediments but can be prone to blocking if the sediment is too large which is why we've implemented a mesh filter that is used prior to the ceramic filtration.

Guy: Depending on the success of the product, Unilever are interested in prototyping the real thing which would be a major step forward. We're currently researching into distribution methods. Do you have any suggestions?

We see this product as a cheap solution that is a major step forward in cleaner water with greatly reduced cases of illness to keep children in schools and for parents to continue their daily work.

Really good questions Bettina & Guy, it's really important that we're able to answer these key questions and that the product reflects that. If you have any further comments or thoughts on my answers, please do so! :)

Hi Dylan.
Thanks for the answers! Sounds like you are well into the development phase. Amazing that Unilever has shown interest in prototyping. How did you engage with them? (if you don't mind my curiosity...)

A few further questions -
As the mesh component will be important to block passage of large sediment do you foresee that this component may actually wear out and need to be replaced at some point? If so will you offer it is a separate part for purchase?
$1 for this device does not seem inexpensive as many folk exist on $1 a day (I read that somewhere on this challenge.) - any chance that that figure can be realistically lowered? Have you done any research as to whether locals will understand the importance of this device and will be willing to invest in it?
Back to the question of how you will know that the device actually filters out pathogens - are you planning to do tests of water quality with the device before you take it to market? I would think this would be a very important step if you were to sell it for this purpose. Do you have any references on ceramic's ability to filter out pathogens?

In terms of distribution - not sure exactly what you mean - but this research post is exciting in terms of utilizing an existing distribution system to deliver something new/different -
