CAWST gives biosand training in Michigan


Members from Engineers Without Borders, Rotarians, missionaries, and other concerned individuals have come together to learn about implementing household water treatment projects to help address this global issue. They focused on the cement biosand filter which they constructed themselves from inexpensive and simple materials such as concrete, sand and gravel. The biosand filter is effective in removing pathogens and providing improved water supply to those without safe water.

Calgary-based Centre for Affordable Water and Sanitation Technology (CAWST) conducted the technical training and consulting services, and acts as a catalyst to make water and sanitation projects a reality for the poorest of the poor in the developing world.
Bob Johnson took the training last year and returned to tell the group how he started a biosand filter business and rainwater retention project in Rwanda. Attendees will take their training to Mexico, Kenya, Senegal, Dominican Republic and Nicaragua.
