Founded on Quaker principles, Friendly Water for the World (Friendly Water) works with very poor communities around the globe on ways to ensure their own safe drinking water supply. Friendly  Water relies on knowledge-sharing and training, providing the knowledge and resources necessary for communities to take charge of their own water needs. Their model focuses on local representatives and training with an eye toward sustainability and self-sufficiency. Their project installations include a trusted model of water safety: biosand filters, water catchments projects, sanitation education, and well-head repair training programs.
