Latrines are usually the most appropriate sanitation technology for rural communities. However, without an adequate understanding of proper design standards and the community context, a latrine project can be a complete failure, with community members returning to previous methods for sanitation. Engineers Without Borders – USA (EWB-USA) has provided humanitarian engineering services since 2001 in rural communities on infrastructure projects and has collected many lessons learned to assist those in international development to complete sustainable latrine projects which will effectively decrease water-borne and water-related illnesses in communities. These design standards and best practices are included here for the benefit of rural communities and those who serve them.
