Clean water through natural filter technology

With the help of the project, 1.7 million people in Cambodia receive clean drinking water through ceramic water filtration systems. The filtration is based on an ancient method in which the water seeps through baked clay. The pore size is so small that it removes up to 99.99% of impurities. Every hour, 2-3 litres of water flow through the ceramic vessel into the storage tank. One filtration system covers the needs of a family of five.

The water purifier eliminates the need to boil water with wood or charcoal. It avoids CO2 emissions, reduces air pollution, lowers fuel costs and helps protect Cambodia's endangered forests.

Produced locally, the filters have the advantages of being effective, inexpensive, low maintenance, chemical free and easy to use. In addition, the production and transport of the filters provide income opportunities for the local population.

How does technology for clean drinking water help fight global warming?Two billion people in the world have no access to clean drinking water. Many families have to boil their drinking water over an open fire, resulting in CO2 emissions and deforestation. Where water can be cleaned chemically (e.g. with chlorine) or mechanically (with filters), or where groundwater can be provided from wells, these CO2 emissions can be avoided. Clean drinking water projects in the ClimatePartner portfolio are registered with international standards.
Contribution to the UN Sustainable Development Goals (SDGs)
Good Health and Well-BeingClean drinking water and a 78% reduction in smoke improve the health of the people, especially children by combatting child mortality and improving maternal health.
Climate ActionPeople avoid carbon emissions by not boiling their drinking water anymore. This avoids 84,700 tonnes of CO2 emissions annually.
Life on LandThe reduced demand for firewood helps preserve local forest areas and biodiversity.
