RDI - or Resources Development International Cambodia - have a variety of semi-unrelated facets to their organization. Making ceramic filters is one of them, another is educational TV in Khmer, and another is running a NGO laboratory testing water quality throughout Cambodia. Engineers without Borders currently have Environmental Engineer Isabelle working at the facility to help plot how quickly the filters can dry for enhanced production.
With the ceramic filter production the basic concept is that of Potters For Peace (whom I covered in an earlier Rainwater HOG newsletter - click here to sign up!) but improved for local manufacture. Ground rice husks are cast into the pot. These burn out during firing to create the right porosity to filter arsenic. The fired pots are soaked, then coated with silver and finally set into a plastic bucket and packaged with cleaning brush (including a natty slot for instructions) and sent out to villages. $10 buys a filter that should remain effective for 3 or more years. Best yet, the whole setup can be replicated for between $3 and $6k, allowing other commun
