The project sells CWPs to families across Cambodia. Once the water has passed through the ceramic filter the clean water is stored in a plastic container, giving safe drinking water at just a turn of the tap. The filters are produced at a purpose-built factory in Cambodia providing employment opportunities to locals. The filters have a number of low-interest financing options and many are sold to NGOs who offer them at a subsidised price.

The simple yet highly effective technology, the project helps thousands of Cambodians access clean water, leading to a number of knock-on benefits. As indoor smoke is reduced, respiratory health improves, while clean drinking water is an essential component to combatting diarrheal illness. Overall public health is improved, which helps to stimulate economic activity. With the reduced need for wood fuel, families spend less time gathering wood and less money buying it, freeing up their resources for other activities. Less pressure is therefore put on Cambodias vulnerable forests.
