Putting others first will be our strength and the source of our success.

In 1997 I was traveling to inspect projects I was managing for Hagar International, an international NGO working here in Cambodia. As I was meeting families we were serving, I met a woman who had been part of our residential program in Phnom Penh. She had completed our program and returned to her home in the province. When she left our residential program she and her son were healthy and thriving.

As soon as I walked into their home in the province I knew something was wrong. Amy* and her son had changed dramatically, both had lost weight and her son’s stomach was swollen and distended. In talking to her I began to understand the problem. Amy* told me that they had enough food to eat, their shelter was adequate, they had a supportive community, and they even had enough water to drink. As we talked I asked her what water they were drinking. She pointed to a water jar in the corner of their small home with a scrap of wood covering it. I removed the wood covering the jar and immediately knew why their health had changed so dramatically. The water in the jar smelled terrible. It was cloudy, brown and there was a slimy film floating on the top. While Amy* and her son had access to an adequate volume of water, the water they had access to was contaminated with bacteria and parasites.

When I returned to Phnom Penh later that week I talked with my director about the threat that lack of clean water posed to the people we were serving. We searched locally for a method to provide clean water but were not able to find an economically viable solution. It was almost two years later that the director found a solution on a business trip to Canada. While in Canada to meet with a partner organization, he was introduced to BioSand filter technology. When he returned to Cambodia he asked me to begin developing a program to implement this technology for our project sites located in rural areas.

13 years after I first met Amy* and her son, the BioSand filter program had expanded to a point where it no longer fit under the mandate that Hagar International was operating under. In October of 2010, Clear Cambodia was formed as a locally run NGO serving the Cambodian people.

Clear Cambodia now has operations in 6 provinces. Each year Clear Cambodia assists local communities in constructing and installing over 21,000 home BioSand filters, and 90 school BioSand filters.

These investments in the communities of rural Cambodia are made possible by the generous support of our partner organizations, Charity Water and Samaritans Purse, and private donors.
