Diarrheal disease is still the second leading cause of death in children under five, killing 525,000 each year. Globally there are more than 1.7 billion cases of childhood diarrheal annually (WHO). A significant portion of these can be prevented through safe-drinking water however, access to safe drinking water continues to be limited. Often, available treatment options are not effective against all causative agents, too expensive, too low capacity, or not suitable for all environments. For this reason, there is a need to improve on HWTS options.
The successful development would provide a complete drinking water treatment system for end users at a household scale. The design is intuitive and simple, removing challenges associated with training, language barriers, and improper use/set-up. With technology capable of addressing helminths, protozoa, bacteria, and virus, it will have a significant impact on diarrheal disease from any water source. A household purifier capable of treating up to 10,000 L of drinking water without any resupply will also reduce burdens on both end users and humanitarian agencies. In addition to this, the disinfection cartridge will add a small residual to protect against recontamination.
Upon completion of this project, it is anticipated that multiple iterations of the design will have been completed, tested, and reviewed from perspectives of both end users and manufacturing engineers. At each stage of iteration, the design will be evaluated against the key performance indicators of cost, usability, performance, and manufacturability. This will position the HWTS device in a beta stage of development, which would allow MSR Global Health to pursue additional funding for larger scale field-testing, and user evaluations before beginning initial production. Any learnings from this effort will be shared with the greater community to further aid in progress towards bringing sustainable access to safe drinking water to the world.
Tackling the issue of water treatment head-on, the team is developing a next-generation household drinking water treatment system.View
As MSR develops a next-generation water purifier for households in developing countries, it leans on its decades of commitment to water treatment innovation.View
At the heart of the new system is a chlorine doser, meticulously engineered to apply a precise amount of chlorine for the treatment of contaminated water.View
After developing early prototypes, the team sent the treatment system to aid workers for feedback.View
