When Cynthia Koenig, from New York, realized that one in six people lack reliable access to water she wanted to do something about it.

Her solution was a 25-gallon drum that can be pushed or pulled and takes away much of the burden of carrying water on the head, which is the traditional method women use in many parts of the world.

Koenig considers herself a social entrepreneur, a new breed of entrepreneur who has innovative solutions to society's most pressing social problems and still desires to make a profit.

I caught up with her at theThe Unreasonable Institutein Boulder, Colo., where 24 other social entrepreneurs were living in a house and being mentored on how to bring their ideas to scale. Here is our discussion:

Tell me about theWello WaterWheel.

Cynthia Koenig: The WaterWheel is a 25-gallon drum that moves five times the amount of water possible than traditional methods, which is five gallons on the head. So not only is it alleviating women and girls from this tremendous physical burden of water collection, but it's also reducing the time burden; women and girls spend about 25 percent of their time each day collecting water. So by using the water wheel it frees up their time to spend their time on more productive activities like work or school.
