Providing Safe Water for Smaller Communities
Throughout the developing world, the need for safe drinking water is widespread. While chlorine bleach treatments are inexpensive, effective means of killing water-born bacteria and most viruses, they are difficult to transport and store and hard to dose properly. In addition, bleach has a shelf life that is shortened if stored improperly. The end-user has no way of knowing if their bleach will purify their water. For communities of 5,000 or more, water systems involving UV treatment are proving very effective, but require a level of training, maintenance and investment difficult to scale for smaller communities.
The problem of developing and field testing a simple, durable and affordable water treatment system for smaller communities is the current task of PATH and Cascade Designs. Supported by the Lemelson Foundation, PATH and Cascade Designs are co-developing an inexpensive, portable, community-level system using MIOX electrochlorination technology to produce an easy-to-use solution on-demand, from just salt and water. PATH previously received a Foundation grant to help it develop an improved women's condom to protect women in developing nations from unwanted pregnancy and the risk of sexually transmitted infections.
