Water is fundamental to health, but 1.8 billion people in the world drink from contaminated sources. How can we get clean water to the people who need it?
Equip them to make it themselves – easily and cheaply. That’s the solution developed by a team from Seattle.
Using expertise gained from making gear for mountaineering expeditions, their initiative aims to provide 500,000 people in the developing world with safe drinking water by 2017. At the heart of it is a foolproof system called the SE200 Community Chlorine Maker.
It marries elegantly simple technology with cutting-edge design, collaboration and financing.
Two ingredients, five minutes
The device uses water, salt and a power source such as a car battery to make chlorine, and the process takes only five minutes. The chlorine purifies enough water for a village.
MSR has launched a crowdfunding campaign aimed at raising $50,000 to deploy 2,500 of the devices by the end of 2017 through World Vision and Operation Blessing.
Development of the device began about 10 years ago when Seattle-based global health nonprofit PATH came to MSR with the challenge of identifying the best way to decontaminate clean water in impoverished areas.
MSR, which harnessed its manufacturing and engineering expertise and experience making water purification systems for backpackers, explored 85 different technologies, MSR marketing head Jane Mauser said at a recent conference.
The team concluded chlorine was the best solution because it is portable, long lasting, inexpensive and effective at killing bacteria, viruses and protozoa that cause diarrheal disease.
Easy and effective
From there, the design process focused on crafting an extremely simple device with no need for measuring or written instructions. The team decided the best size was a system for about 200 people.
“Our focus was low cost so we wanted to take all the bells and whistles off,” said Brian Gower of World Vision. But after testing with communities in the field, they added a bell to notify when the chlorine was ready (so that busy users could attend to other work) and a power indicator.
Villagers add salt and water based on lines on the side of the clear chamber, then push a button. The device self-corrects to make the same concentration of chlorine every time.
“It’s magic – salt, water and electricity make chlorine. It blows people’s minds all the time,” said Jesse Schubert of PATH.
“The ease of use and the effectiveness of the treatment are things we love,” said Gower.
MSR sells the chlorine makers for $239, and charities get funding from donors to buy them. The devices have a stated lifespan of five years, but units in the field are going strong at seven years old.
By working with the charities, MSR understood user needs better and got feedback on early models. The charities also provide training and support as devices are deployed.
The partners see a need for a larger system that could be used for thousands of people in refugee camps, larger communities and disaster areas, so that may be on the horizon.
“We have learned that partnership is powerful,” said Mauser of MSR.
