Clean Water for Disaster Preparedness and Relief

We’re getting great feedback!

I think the DayOne system is a game changer and could have significant impact outside of disaster response. I have seen firsthand the daily effort people in Africa spend on gathering water and think your design could serve as a labor saving device for the water collectors as well as its public health impact.- Keith Neroutsos, Director of Procurement, PATH
DayOne Purification Waterbags™ are a great product – the size and flexibility allowed it to be transported to the Philippines quickly and efficiently. When the next natural disaster hits, Giving Children Hope knows that DayOne Response will deliver life saving water with a product that is versatile, giving us many options to get water to people that need it most.- Sean Lawrence, Executive Director at Giving Children Hope
