Film your elevator pitch.
What specific problem are you solving?
Many places around the world do not have access to clean drinking water. Reason may be due to absence of water itself or absence of electricity to treat the water to make it clean. Also reliable sources of drinking water such as bottled water are very costly and difficult for common people to afford.Also we are not sure about water quality except when we buy a bottled water. And lastly accessibility is a huge issue. Lots of women around the world have to walk miles just to fetch clean drinking water for their family. We are trying to solve all these three problems- accessibility, availability and affordability.
