Approximately 66% of rural Cambodians lack access to sanitation infrastructure, which can lead to devastating effects on health. Populations in flood-prone areas are particularly at risk. EWB will establish and support a network of local entrepreneurs to manufacture and install biodigester toilet systems. This will address the lack of sanitation in flooding and floating environments in Cambodia, and provide households with a cost-effective form of renewable energy. In three years, EWB will enable 25 local entrepreneurs to install 2,500 biodigester toilet systems benefitting 15,000 people. In 10 years, the project will provide sanitation and energy solutions to 1.2 million Cambodian people.
