This project addresses the problem of safe drinking water by constructing and disseminating ceramic water purifiers (CWP) to Cambodian households, particularly in rural areas. CWPs are point-of-use treatment systems which remove microbes from contaminated water.

They are manufactured locally and can filter enough to supply drinking water for a family of five for five to seven years whilst requiring no energy input. Thus, while they replace the current treatment practice of burning non-renewable biomass, they directly lead to the reduction of CO2 emissions.

Sustainable Development – The Sustainable Development Goals

While focusing on reducing greenhouse gas emissions, all our projects also generate multiple co-benefits. These are supportive of the United Nations Sustainable Development Goals.

By supporting this project you’ll contribute to the following Sustainable Development Goals:

Good health and well-being: In Cambodia, diarrheal diseases, mostly waterborne, are the most prevalent cause of death among children under the age of five. By treating contaminated water, this project contributes to the reduction of child mortality from diseases associated with polluted water.

Clean water and sanitation: Ceramic Water Purifiers have been proven to be 99.99% effective in the removal of bacteria. During its course, the project aims to disseminate between 168.000 and 315.000 units over 7 years, improving the lives of 900.000 to 1.7 million people.

Decent work and economic growth: CWPs are locally manufactured creating employment positions during construction and distribution and therefore generate additional income. They also contribute to long term savings by replacing the cost of purchasing firewood and charcoal.

Climate action: CWPs reduce deforestation rates by reducing the use of firewood to boil water. Each unit manufactured replaces approximately 2 tons of firewood each year. During the project’s entire lifespan, it is estimated that between 2.3 and 4.4 million tons of firewood will be saved.

Life on land: Thanks to CWP there is no need to boil water for safe consumption, which relieves pressure from forest resources in Cambodia. This yields direct benefits like slowing soil erosion, the destruction of natural habitats and loss of biodiversity.
