Urban Sanitation Solutions for High-Use, Flooded, and Difficult to Serve Areas

Andreas G. Koestler and Andrew Larsen of the Fontes Foundation in Norway will design and conduct a small field test in Haiti of a new toilet block system that can be erected as a kit in high-density, difficult to serve communities such as refugee camps. The system will feature urine diverting toilet pans as well as enlarged ventilation areas to help eliminate odors and desiccate feces, and will utilize used billboard fabric as waterproof walls, ceilings, and bladders to store excreta and contain pathogens that can foul water supplies.
