Our organization, Together Association for Development and Environment (TADE), intended to provide rural Egyptian villages with affordable, low-tech water sanitation systems that can be sourced and built locally. Water sanitation systems are of major importance in Egypt as most wastewater in rural areas currently is not treated, polluting groundwater, causing health problems, and contaminating food/crops. The technology of TADE’s sanitation system is proven and has already been implemented successfully in one Egyptian village.
