Buying water from refill stations in Indonesia costs more than $100 a year per family and the water is often contaminated. Some 26,000 Indonesian children die annually from waterborne diseases such as diarrhoea.

Based in Bandung, West Java, Nazava Water Filters enable lower income households to purify their well or tap water without the need to boil it by burning wood or using electricity. This reduces disease and sickness, lowers household costs and reduces CO2 emissions.

The company has sold over 53,000 water filters and over 200,000 people acquire their daily drinking water from a Nazava water filter.

The Award judges said:

“With Nazava Water Filters we have the three A’s: accessible, affordable and aspirational. Their model of providing safe clean water to families in rural Indonesia has huge potential for replication in other parts of the world and doesn’t require massive infrastructure behind it to be successful.”

According to Lieselotte Heederik, CEO of Nazava Water Filters:

“We are extremely proud to be an Ashden winner. The Ashden Award is very prestigious and we are really excited about it. Being chosen is a huge recognition for the work of our great team to get safe & affordable drinking water to the people that need it most.”

Sarah Butler-Sloss, Ashden’s Founder Director, said:

“Sustainable energy is interconnected with so many other huge issues in the developing world such as access to clean water, livelihoods, women’s empowerment and access to financing to be able to start a business.  This year’s Ashden International Award winners are, without exception, all transforming lives and we are proud to have the opportunity to support their game-changing work.”

Winners will be presented with their Award at a prestigious ceremony being hosted by BBC  journalist Mishal Husain at the Royal Geographical Society in London on Thursday 9 June, when the winners of the Ashden UK and International Gold Awards will also be announced.
