Worldwide more than 700 million people lack access to quality sources of drinking water. Chlorine is one essential ingredient for the creation of clean drinking water. To make chlorine easily available, Mountain Safety Research (MSR) and PATH an international, nonprofit organization have come together to create a chlorine maker that requires just water, salt, and electricity from an outlet or a vehicle battery. It is the MSR SE200 Community Chlorine Maker.
The MSR SE200 creates Chlorine with the push of a button to make safe drinking water. It does this with water, salt and electricity. Each batch produces enough chlorine to make 200 liters of water that’s safe to drink. A supply chain innovation, the chlorine maker lets users treat water on the spot at wells, water trucks and other common sources. Small, portable and easily mastered, it requires only salt brine and electricity from a car battery or mains power. Most importantly, it allows families, leaders and entrepreneurs to control their supply of safe drinking water.

The SE200 Community Chlorine Maker is changing how citizens in low-resource communities around the world are creating safe drinking water.
Over the past seven years, MSR and PATH have field-tested the SE200 in more than 10 countries, including Kenya, Ghana, India and Haiti. MSR released the device commercially in May. According to MSR, each device costs about $200 but it can treat enough water for 200 people for about five years.
