Nazava Filters shares with us a recent article they wrote in Water Quality Products magazine about how their product addresses the need for safe drinking-water in Indonesia. The article also mentions three benefits of their model which other organization may find helpful: distributing through a network of micro-entrepreneurs to reach people across the country’s 17,000 islands, using mobile technology for data collection and marketing, and providing local women with an income-generating activity.

The World Health Organization and 14 collaborating research institutions have published new burden of disease figures showing the impact of poor water, sanitation and hygiene. They estimate that 842,000 diarrhoea deaths in low- and middle- income countries during 2012 can be attributed to poor water, sanitation and hygiene. This amounts to 1.5% of the total disease burden and 58% of diarrhoeal diseases. In children under five years of age, 361,000 deaths could be prevented, representing 5.5% of deaths in that age group. Read the full article in Tropical Medicine & International Health.

The WHO & UNICEF Joint Monitoring Programme for Water Supply and Sanitation has released its 2014 update, with estimates on progress up to 2012 on access to improved sanitation and improved drinking-water. Improved drinking-water coverage in 2012 remains at 89% globally – which is 1% above the Millennium Development Goal drinking-water target. This means that, in 2012, about 748 million people relied on unimproved drinking-water sources. Download the update.
